PSA: Sorry Everyone, No Wi-Fi Calling On The Nexus 4

In the hopes of clarifying a bit of confusion and concern I see in the comments, I’ve reached out to T-Mobile to confirm that there will be no Wi-Fi calling on the Nexus 4. Now, odds are greatly in favor of this not being a T-Mobile decision anyway as a Nexus device generally doesn’t receive any carrier input. Therefore, T-Mobile likely had zero input in the manufacturing of the device and couldn’t request the inclusion of this feature. Hopefully, this won’t deter anyone from picking up the Nexus 4, but I thought you all should have a definitive answer.

    Thanks for hunting down the facts, David. A small let down, but with updates straight from Google, who cares?! Not this guy.

    • Dakota

      Does anyone know if/when the Galaxy Nexus would get the 4.2 update? One of the features was a photo thing and i wondered if that would work. My 2 negatives of the GNex are the 5mp camera (I really need 8) and the terrible volume issues. Its just so hard to hear ringtones unless the phone is next to you in complete quiet. The battery doesnt seem super but I guess thats the case with most Android phones. If you actually use them, you need to be able to charge it throughout the day

      • remister

        +1 on the volume issues. I hope they resolved it on the Nexus 4.

        • princeasi

          It’s manufactured by LG, there will be a whole lot of things need resolving loll… sorry but I can’t help but think about the G2x every time i see LG.

        • remister

          It is going to be a Nexus device, so we shall see.

      • theking_13

        You “need” 8, really? Do you know what megapixels even defines? Because its not quality. The sensor used defines that.

        • kalel33

          Exactly, I haven’t met a single camera phone user that needed more than 3MP, which is still much greater than the resolution of a 1080p TV or most monitors.

      • Nick

        this hasn’t been announced yet although I’d guess Nov 13

  • pholocity

    People shouldnt be surprised by this. This is a pure google device so that means no carrier provided software goes into it.

    • HalfwayCrook

      Exactly! I’m def getting this phone

    • CoupD

      Well people that never had a Nexus phone and see it being sold by tmobile could possibly expect wifi calling availability. I didn’t expect necessarily, but I didn’t also think that it wouldn’t be there.

      Since I depend on it, the lack of it is the final nail. No SD was bad but not a killer, no wifi calling is a killer.

      • Josue

        agreed…cause according to Mr Duarte putting a SD card to a phone “confuses” users

    • Josue

      people will still ask regardless

  • Jimmy

    Give it 3 to 6 months to be will allow people to download wifi calling as an app, now that u think about it tmobile already has an app for tmobile customers. Called BOB SLED CALLING by tmobile

    • the2000guy

      But is possible to call directly to phone numbers? I tried on Iphone but you have to create an account and haven’t found anything related to call directly to phone numbers

      • cozzy

        On bobsled you get a dialing pad to punch in phone numbers. You can also try goove ip which works with google voice. You get free wifi calling in the US and canada.

    • squiggleslash

      Why would Wi-Fi calling be available for the Nexus 4 in 3-6 months if the Galaxy Nexus still doesn’t have it?

      Bobsled calling, BTW, is a social networking VoIP app. While it does, currently, let you make free outgoing calls over Wi-Fi, you can’t receive calls sent to your T-Mobile number and it’s hardly the integrated system Wi-Fi calling is.

      What would be nice would be for T-Mobile to offer SIP credentials for anyone who wants them, so we can just install bog-standard SIP client on our phones (or use the built-in one)

  • Deadeye37

    It would be awesome if they made WiFi Calling available on the Play Store (only compatible with T-mobile Nexus 4).

    It would be really awesome if it was available to download for any device on T-mobile so that it wouldn’t be pre-loaded. Then again, there’s probably certain files that can only run if they’re flashed on the phone.

    • Dakota

      Well guess people who need wifi calling (along with 10gb of data) would be the ones to pay more to get the Tmobile version.

      • UMA_Fan

        Theres only one version of the Nexus 4. Its really all up to Google to support WiFi Calling or not.

    • Roger

      The problem is that it isn’t really technically possible. In order to do the wifi calling they need deep and meaningful access to the SIM card which has all sorts of security mechanisms and implications. The phones that do have wifi calling have modified kernels in order to deal with SIM card issues.

      Tmobile could possibly pull it off if they didn’t have handover to cellular networks and weakened some of the security issues.

      • kalel33

        That’s not really true. I ran Cyanogenmod with a custom kernel on my Mytouch 4g, used the .apk wifi calling app on XDA, and never had a problem using it. The friend I sold it too still has the phone and it works just fine with WIFI calling.

        • andy_o

          Wha? Did you read what he wrote?

        • kalel33

          Yes I did. He stated that the current WIFI calling phones have a specific kernels developed by T-mobile and that’s the reason why the Nexus 4 isn’t able to do WIFI calling. This is incorrect because I’ve done it with third party kernels, with custom ROMs.

        • andy_o

          “modified kernels” doesn’t mean “developed by T-mobile”. What I got from it is that it’s not possible unless you are rooted and unlocked.

        • kalel33

          He states that it’s “it isn’t really technically possible”, to which I gave information that disproved his statement. If we want to go your route then you don’t even need a modified kernel, because the HTC HD2 has WIFI calling without any change to the kernel, which never had WIFI calling to begin with.

        • andy_o

          He was responding to a post saying that it should be downloadable from the store. That’s not technically possible unless you think T-mo would come out with an app for root users.

        • zx6guy

          Then you’re doing it wrong because it works fine for me.

        • kalel33

          I think you replied to the wrong person, because it works fine for me too.

    • timmyjoe42

      Hopefully the app is made available from another source for rooted users…

    • dorathy

      just get a windows phone 8 with intagrated skype – and the 8x is a signature phone, so no bloatware!

      • FlyerR

        What does skype have to do with this discussion? You can have skype on any android phone and have had it for a very long time.

  • antmisk

    I’ve learned to deal with no wi-fi calling on the Galaxy Nexus. I’d love to have it, but it’s not a dealbreaker.

  • Well that suck, looks like I’m getting a GS3 then. WiFi calling is the only reason I get a specific phone =[, that’s to bad to cause i really wanted the nexus 4 for the hardware.

  • That in itself should be reason enough to not rely on the cloud for anything! Not sayin’ SD, I’m sayin’ larger on board capacity.

  • slaggyb

    I careless about wifi calling and hardly use it on my bold 9900…am getting the nexus 4 from google to compliment with ma berry.

  • Matlock

    I dont know why people were thinking this phone was going to have wifi calling, it is the exact same phone Google will be selling on the Play Store, just at a higher price point. I cant wait til the 13th. The 13th is going to be a big money spending day for me, getting CoD black Ops 2 for both PS3 and 360 and also ordering my Nexus 4.

  • drivethruboy168

    Yay… Which means no T-Mobile bloatware!!!

  • Jimmy

    Tmobile has an app available on the play store called BOBSLED CALLING, it’s a free downloadable app that let’s you call over wifi(I think without even using minutes) its available to any tmobile android so should work with the nexus 4

    • whiteiphoneproblems

      Looks cool — but it won’t accept incoming calls (or will it?), which is a big part of the appeal of Wifi Calling…

    • Roger

      It also requires a Facebook login

      • TBN27

        Not necessarily. You can create an account without facebook.

  • pick me a winner

    i guess this is no biggy im still gonna grab it when i can upgrade to the unlimited data plan. but the note is still inconsideration

  • jason h

    bummer…wifi calling is a deal killer for me. Ill keep waiting for an app and stick with my current phone.

  • Chris

    It carries the brand of Nexus for a reason!

  • GwapoAko

    Can you install magicjack app in Nexus 4? It is like wifi caling.I installed it in my iPhone 4$ before we went to Europe last June. I used it to call US numbers and it worked fine with wifi.

    • MacRat

      Just get a SIP account. The Android OS has a built in SIP client.

  • the2000guy

    I would consider buy it if the wifi-calling app was available.

  • Bob Omb

    You can accomplish the same thing using GoogleVoice and GrooveIP to make calls over wifi. If you’re already using GVoice for calls and texts the setup is simple.

  • thebeastglasser

    Get Google Voice, problem solved.

    • Deadeye37

      That’s what I was just wondering. I already have Google Voice for texts. If someone calls my google voice number, it goes completely through WiFi and doesn’t touch T-mobiles network,.correct? Also, if I setup my phone to use Google Voice for calls, can I choose to still make & receive calls over my regular number? I use WiFi calling at work since I don’t get any reception from my desk.

      • archerian

        you would still end up using minutes as GV ‘calls’ your number – everything to do with Voice is through traditional t-mobile calling. Unless you have Fav 5 or something that makes calls free from a certain number.

    • MacRat

      Well, GV just forwards the call to your cell number unless you have a SIP account set up. The Android OS has a SIP client built in.

  • Chris Sanner

    I would care, except that ever since t-mobile moved from UMA to WFC, it’s been pretty lousy. I gave up on it.

    • Durandal_1707

      In what way? I’ve found that the IMS-based Wi-Fi Calling on my GS3 has been, so far, much more stable than the GAN-based implementation on my old G2x, which tended to either severely slow down the phone or lock it up outright.

      • ogopogo

        Hate to differ with you, but the UMA implementation was far more solid, and provided tower handoff seamlessly. WiFi just drops.

      • archerian

        both UMA and ‘Wi-Fi calling’ are GAN based and are UMA, the only difference is how the tunnel is setup. I have been using UMA since they launched mid 2007, always found the hardware implementation to be able to better and faster connect to wifi hotspots. It could also do seamless handover into and off wifi to cellular. This was useful where I would start a call on Wifi, then move into cellular and not get charged as it depended on what was being used when the call started.

        I haven’t used a G2X, but I believe its implementation is also software based.

        • Durandal_1707

          Never used the old hardware-based devices. The G2x used a GAN-based software implementation by Kineto, and it was horrible and very unstable (though this could easily have been LG’s fault, as everything else about that phone was also horrible and unstable). Starting with the Galaxy S II, T-Mobile’s been using an IMS-based system instead which, in my experience works worlds better, so anyone who’s got a bitter taste in their mouth from the Kineto app may want to give WFC a second chance. It doesn’t do handoffs, this is true, but it’s possible that future versions will gain that ability once T-Mobile switches to LTE, since VoLTE is also IMS-based.

        • Chris Sanner

          That’s good to know.

          Yes, it’s the hardware version I used to love (back on the blackberry devices) and for a while was my primary reason for remaining with t-mobile.
          I’ve got something to think about now, GSIII vs Nexus 4…hrm.

      • Chris Sanner

        sorry this is such a late response – but having never used the the IMS-based wifi calling I can’t comment. I only had GAN and UMA. UMA was far superior. Can’t speak to IMS.

        • Durandal_1707

          Well, you’ll get no argument from me. The GAN-based Android app for Wi-Fi Calling sucked. The IMS implementation seems to be working much better for me than the GAN app did, with the only real issue being the lack of handoffs (which might go away once we switch to VoLTE, which I understand is also IMS-based).

  • Dakota

    Is wifi calling for people who dont get cell service at home? Didnt realize so many people had that problem – so they cant make calls on cell phones on any other carrier? WOW… I just ported from Tmobile to Straight Talk. Ive read so many different things about them so I hope it goes well. Porting went smoothly and happened in less than 30 minutes despite sayig it could take 2 days. But I stuck with Tmobile instead of going with ATT just cuz Ive been used to them…but maybe I can switch at some time to compare. I do want to ask people about HSPA+ because Im using last years Galaxy Nexus which is HSPA+21. Ive done speed tests in all parts of town and Ive never even hit 4mpbs. That doesnt really seem 4G type speeds…but I guess 2-3 average is what I can expect on Tmobile. So Dont really see differences betwee the +21 and the 3G. Are other cities different?

    • ogopogo

      Think outside the box – I have used WiFi calling + Google Voice while traveling internationally. All you need is a WiFi connection, and your calls are free (incoming, and outgoing) – I have done this on the last 5 trips to Europe and Dubai.

      • Newmexican

        Confirmed, used this on multiple occasions

    • Camille

      I use WiFi calling when I’m at work because I do not get a signal inside the building. And, when I have to be there for 8+ hours, I need service in case something happens with my kids. And, I’m not the only one with service issues. None of the Verizon or sprint customers get Service in the building either. I’m just the only one that has an option with WiFi calling. So, as nice as the nexus 4 seems, I’d have to pass on it for that reason.

  • jerry

    Why are people relying on a carrier app for this? Things like this are the reason that US carriers are so messed up. Google voice and groove IP for all calls and texts. Just pick a number and go. Use it forever. Any carrier, any sim. This has been possible for years. Although a lot more simple now than it use to be.

    • jason h

      Fair point but its inaccurate to assume that Google voice will be free forever…in fact its likely to be moved to a pay-for-service model over the next couple of years.

      • Boom!

        That is completely against what Google does? So I don’t know where you get the pay for service part….google’s mo is not to make people pay for anything they don’t have to…

        • Deihmos

          Google voice defeats the purpose of wifi calling. Not like you can make a google voice call on wifi only. Wifi calling came in really handy when I was abroad.

        • squiggleslash

          @Daihmos You can if you have the right app. I believe there’s something called GrooveIP for it or something. I haven’t tried it, largely because I don’t want to complicate my set up. I know it works in theory because, well, try Google Talk in your browser to make and receive calls, using your GV number…

          A lot of the problems here are about how complicated it gets when you start using third party “solutions” to this. I want something basic – when I’m on Wi-Fi I want calls that are made to my T-Mobile number to be delivered to my phone via the Internet, and outgoing calls to be delivered to T-Mobile over the Internet. And ideally I’d like it to be such that no minutes are used. None of the solutions people are proposing here, Bobsled, GV, generic SIP accounts, etc, actually do this. They usually fail on the incoming calls part.

          Wi-Fi calling does do what I want it to do. It’s a shame T-Mobile doesn’t open it up, allow users to register over SIP or something.

        • andy_o

          I think you can port your number to Google Voice, it will save you a few headaches and provide much better features (per-contact answering machine, to name just one). Also, nowadays it’s not that hard to change your phone number. Talkatone is another app that lets you use GV as VoIP, but its paid option is a service. Groove IP works well for me, but you have to make sure you have a good connection. I’m pretty sure this is a Google Voice thing. When there’s a weak connection, instead of breaking up, you get massive delays, which is way more annoying. Incoming calls work fine with both.

        • Newmexican

          Wrong, when I am in Europe, all my calls within Europe automatically go through Google Voice, when I am on WiFi calling

        • andy_o

          Google have been going year by year, announcing that GV calls to the US will be free “through 2012” (and 2011, and 2010). Nobody really knows if they’ll extend it another year, but it sounds a bit like so people don’t get their hopes up too much that it will be free forever. Skype also started being free, that’s how it gathered so many users. Now the bastards even charge a connection fee.

        • Wilma Flintstone

          but don’t you have to pay to use Google’s Cloud service?

          Google is a business, they will go out of business if they don’t charge for something unfortunately.

          This is also one reason I will not use the cloud service. I will not pay to rent memory. I’d rather own it by using a SD card.

    • Great idea, however, GV doesn’t support MMS (unless you are on Sprint). Is there a way around this?

  • Still getting the phone. Only difference is plan.. with wifi-calling the $30/prepaid plan would be perfect. w/o wifi-calling I’ll just stick with the usual value plan.

    • You dont get Wifi calling on this plan You have to be a post paid customer to get wifi calling free

  • Dakota

    Anyone know if the Galaxy Nexus will still be sold? It disappeared from the website but wondered if theyd drop the price and it would be like an iphone4 to an iphone5. They have to have stock of it left so do they dump it in foreign markets or what happens. I really think that GSM prepaids need to team up with Google to push the Nexus 4…For people who want a high quality phone at an affordable price along with cheap prepaid plan, thats the way to go. Often prepaids sell you expensive phones that still are locked to their network…This is the way to go if you dont need huge data amounts …the savings would add up quickly. Things like Straight Talk or Simple MObile are half the price of ATT and Verizon. Many of you are much more educated on smartphones than I – so if you use that internet calling you can even get that TMobile/Walmart plan where youd get 5gb of 4G data and 100 min for only $30…That has to be the best deal out there for you guys

  • Paul

    I had heard awhile back that the implementation of Wi-Fi calling was supposed to move to an app downloadable from the play store. Is this no longer the plan?

    It seems that many people do not understand how useful and seamless it is for people who have signal strength problems. Plus Wi-Fi minutes don’t count towards your total minutes count. This feature is the only thing keeping me from a nexus phone.

  • jian9007

    Not concerned about it since I never use it anyway. It can’t be modded and ported to any phone either, since T-Mobile doesn’t open source the application (though they should).

  • remister

    Even though this is a Nexus device, too bad Tmobile has control of the pricing… I heard that Tmobile version have a bigger onboard storage. Let’s just see if it is worth $499.

    • thepanttherlady
      • Guest

        That’s the information that I went by and used it to tweet about it, @tmobilehelp tweet-replied stated that there is going to slight hardware changes, stay tuned for more info. I was not sure if they were pulling information off their asses, but we shall see, come November 13th.

      • remister

    • David

      Google play is going to be selling the same phone 16gb for $349.99.

      • Josue

        and the tmo version full price is $499

  • ogopogo

    So, once again….what is the benefit of paying more for this phone from Tmo?

    • remister

      Financing payments :P

      • bob90210

        You’re better off buying from Google and putting the $150 ($350 purchase price – $200 tmobile’s down payment) on a credit card. Even if the card has 20% interest, it will take less than 11 months to payoff the balance instead of 20 months with tmobile.

  • Alvin B.

    In a perfect world, T-Mobile could put out a CUSTOM ROM that could installed to provide Wi-Fi calling ;)

    • Not a CR, a maintenance update is more likely. A CR will void any warranty but a maintenance update may present updating difficulties too if wifi calling is hardwired into the OS. Updates from the great goog or wifi calling?

      • kalel33

        It’s definitely not hardwired into the OS. I know they told the reps that when they did the SIM switch but my Cyanogenmod run Mytouch 4G just kept on working with WIFI calling, even though they said it wouldn’t work.

  • Jacko98

    My daily phone is the Gnex but II keep my Blackberry Bold with UMA (firmware-based) wifi calling when travelling abroad (Europe and South America). Works perfectly, much better voice quality than using calling cards and its free!

  • Tyberious

    I give zero shits about wifi calling. Just let me at that sexy glass backside. I need a phone that isn’t crippled by bloatware and toucwhiz.

  • Why is T-Mobile carrying this when the benefits of its supplier undercut its own value? No Wi-FI Calling still has 42mbps , no LTE bands….T-Mobile should just advertise buying thru play store instead of carrying the device

  • Qbancelli

    This is great news! It means this phone is untouched by ANYONE!

  • TBN27

    As contingency, there is Bobsled.

    • Newmexican

      WiFi calling in combination with Google Voice makes travel to Europe soo much better. I use this a lot. Bobsled does not help me with that. So if the more expensive Nexus 4 from TMO has nothing like this to offer, I will have to pass on the Nexus 4.

      • TBN27

        Oh you use google voice on top of wi-fi calling. Got you. I did it differently. I used wi-fi calling plus the internationl talk and text service add-on to call around the world when i am out of the country. So because i am willing to go to a nexus phone, i will have to use bobsled as a poor substitute for now.

        • Newmexican

          Yup, when calling the US from abroad I use regular minutes (BobSled might be an option for that), when calling within Europe,Google Voice automatically takes over and I make calls at 2cts/min. Thinking this over, I might consider just using my laptop to make or receive calls from within Europe (hate to have to carry a second phone with a local number). So I still might play with the Nexus 4 in a TMO store. If it is really very good, I might reconsider (but will not buy from TMO, if there is no extra benefit for paying 500 instead of 350 dollars).

        • Newmexican

          I finally decided for the Relay 4G. Costco sells it for $99.00 and you do not have to deal with any mail-in rebates. They do not have it in store or on their website. But the stores can order for you, ships within 3-4 business days. I am eagerly waiting for Friday :-)))
          I just decided that I will not want to give up WiFi calling. So I will have to deal with the TMO crap-ware, hope I can at least disable it

  • noelsito

    well it was pretty obvious. plus, either you want bloatware or you don’t. it’s a nexus

  • FILA

    T-Mobile should just release the damn app on the Play Store by now instead of being greedy

    • philyew

      It isn’t just an app. It has to be engineered into the device. If it was an app, someone over in the XDA community would have hacked it out already and made it available for side-loading.

      • kalel33

        Really? Then explain how the HTC HD2, a Windows Mobile phone that never had WIFI calling, was hacked to get it to run WIFI calling just fine? XDA community has made it available for side-loading for many devices, including one’s that run custom ROMs.

        • philyew

          I stand corrected about the XDA modifications, but do they do that without modifying an integral part of the base build for each device? In other words, would it be possible to produce a single app which could run on any present or future device supporting the relevant OS versions?

          If they have to create a device-specific modification each time, at a layer not normally modified by applications, then TM couldn’t create even an unique device-specific app in the Play Store. In the case of the Nexus series, they wouldn’t be able to do that anyway because it would contravene Google’s first principle, which is that the device carries a bare bones OS.

          Having run a quick check over in the XDA forums, I’m afraid I can’t see anything that indicates that a simple .apk file is sufficient to load wifi calling into a device. Everything seems to talk about the need for at least additions into the system/lib folder structure, which I think you couldn’t do on an unrooted device.

      • mikkej2k

        In earlier versions of Wi-Fi calling , it had an icon just like any other app. Even though it’s more intergrated into the OS than a normal app , if your looking at just the icon you would think ” why not just offer the Wi-Fi calling app in Google Play store?”

  • UMA_Fan


  • UMA_Fan

    Its kind of sad the only smartphone manufacturer that went all out to support Tmobiles Wifi Calling on EVERY device at the hardware level was RIM… and they are FAILING. Apple, Google, and Microsoft seem like they could care less about Tmobiles WiFi Calling.

    • Matlock

      so just buy a cheap t-mo with wifi calling and use that whe you need the wifi calling! I have a BB Bold 9780 sitting around for just such a reason. the only time I use it, is if I know im going to be on the phone for a long time (1000mins fam plan) and dont want to burn through my minutes. So I use it wifi calling in those rare instances. Other than that, My Galaxy Nexus has been super reliable.

  • Grimbeaver

    I can deal with the no Wifi calling as I don’t have that now on the Galaxy Nexus. But if you’re still going to charge more then Google Play and not have anything different then screw it I’ll buy from Google.

  • i can see it as a deal breaker for a lot of people .. i almost never use wifi calling but i do use wifi a lot and it’s nice to know that when i do i can still get calls.

    • Arvonn T

      it is a deal breaker for me. I would love to get the Nexus 4.. and not having wifi calling is what kept me from upgrading my G2x to a Gnex.. sigh..

  • TMoFan

    T-Mobile’s wifi calling is really good. I’ve used a whole bunch of voip options but the quality was never the same. I figured it wouldn’t be an option since Nexus devices are clear of carrier customizations. That will be the one thing I’ll miss when I get my mine.

  • Trevnerdio

    Well, good thing they made their Wifi calling efforts open source! Nexus <3s custom roms, so someone just needs to bake it in and boom, IMS calling…

    Definitely a Nexus all the way. No bloatware. Already have version 4.1.2. My old HTC took 16 months to update to Froyo and that’s all and I have a total of 125 MB available for apps. That is ridiculous. The GNex has over 13 GB available. I do not have a problem with battery, last all day with moderate amount of browsing. Found out that widgets used more battery so I don’t have any running. Really glad I bought the GNex from Google and using T-Mobile network.

  • blah

    WiFi calling doesn’t work reliably anyway. So who cares?
    I turned it off all together after missing the umpteenth call because of it.

    • Exactly! but I’m sure someone on XDA will get it p and running regardless.

    • kalel33

      I never had a problem with WIFI calling. Maybe your wireless network isn’t stable or you had a device that had poor WIFI connectivity.

  • mingkee

    wifi calling is good for those who have the unlimited option which can save a lot of calling minutes. Not to mention is can help indoor reception somewhat. In addition, it is also good for business firms that they can save good amount ofbmoney from international roaming.
    Nexus series is intended for free of ANY carrier’s branding. Just check out Galaxy Nexus from Verizon and Sprint.

  • xda got wifi calling working on the HD2 running Android didn’t they? What’s the technological problem here again?

  • Noel

    Hopefully Google some day will include wifi calling to pure Android.

  • David

    Wifi calling is a great option for customers. My wife is over in the Philippines. Before we had monster phone bills cuz of International calling. Now that she has our other phone with her there. She can call me anytime and I can too. It has saved us so much money.

  • Secret Shopper #42

    What are the components behind wifi calling? (I could totally google this). Shouldn’t a wifi-enabled device be capable of this? What’s stopping T-Mobile from releasing the app to the play store? AFAIK, the feature (on the account) has to be turned on if the user will not incur minutes anyway. But doesn’t wifi calling essentially use the VOIP technology like a bunch of other voip apps on the market?

    I ask because, Wifi Calling is one of the top selling points in T-Mobile’s strategy. Making this available– not included, of course– for the Nexus 4 would only benefit them.

    • Secret Shopper #42

      ..just read 5 posts down and answered my question. Didn’t consider the need to modify the kernel. hmm.. more tricky. Eh, sucks for the non-rooted.

      • kalel33

        You don’t have to modify the kernel. I don’t know where that information started, but yes, you’d probably need to be rooted.

  • No WiFi calling???? Absolutely fine by me!!! buying on launch day can’t wait


    If you want Wi-Fi calling just download the bobsled app. I had a customer with an unlocked iPhone in a coverage challenged area and they downloaded it and presto! Wi-Fi calling on the iPhone. Problem solved.

    • archerian

      does Bobsled have the option to take incoming calls?

      • TMOTECH

        I have no idea. Good question.

  • kevev

    Damn. I need wifi calling. Always in bad cellular coverage. Any suggestions as to which device would be good? The GS III is too big for me. Thinking about the LG N9, but I am worried about quality issues. Thinking about the One S but I am tired of HTC build quality. I seem to have lots of problems with their devices.


      I know a few that have the One S and they have nothing but good things to say. Ditto the GS3. There are Apps like Bobsled that allow for Wi-Fi Calling on other devices…

      • kevev

        Thanks for the reply. Do you know how the cellular reception compares between the One S and the MyTouch 4G? That is the current P.O.S. I have right now. It looses reception whenever it feels like it. I have 2 of them doing this with new sim cards.

        • kalel33

          I think you were very unlucky with your 2 Mytouch 4Gs. I was a rep when the phone came out, till last May, and owned one myself, until I bought the Amaze. That phone was about the most reliable phones that T-mobile sold. HTC has the highest reliability ratings of any Android manufacturer.

        • kevev

          Ya it could be a network issue. But getting T-Mobile to acknowledge it and fix the network is next to impossible. I have had this and other issues here in San Antonio since the UMTS AWS network went live and the G1 came out. The towers are spread out very thin in this city. It has always been that way. I am not sure if a new phone will fix that. This is why I am looking for a phone with a very stable radio and excellent antenna. What to do…what to do…

        • TMOTECH

          Sounds like a network issue. My daughter and 2 of my friends have the MT4G and they do not have that issue except when it is busy hour and they are on the edge of a cell. WCDMA shrinks when traffic increases.

    • JR69

      I have the One S, it’s a very good device and the size is actually on the small side with a 4.3 inch screen. Build quality is fantastic and it’s a fast phone, no lag at all.

      • kevev

        How is the cellular reception? That is my biggest concern.

        • JR69

          I think it’s average to good. It’s subjective to how well TMO is in your area. My wife has a Samsung GSII and I would say that both are similar but the GSII might have a slightly stronger radio.

          I always thought Motorola always had the best cell radios but obviously that isn’t a choice.

        • kevev

          Thanks for the reply. I agree with you about Motorola. I had a Defy and it held signal as good as a Blackberry.

  • Couldn’t you use Bobsled? I think that’s a wifi-calling app for T-mobile that’s compatible with phones that don’t offer T-mo’s wifi-calling by default. It’s been awhile, but I seem to remember it being call-out only though. :-(

  • briankh

    I use GrooveIP and google voice for wifi calling. I’ve used around the world and it works great. It works better than T-mobiles wifi calling.

  • JR69

    That is too bad because I have spotty coverage in my house and use Wifi calling all the time when home.

  • Bcrain21

    I have t-Mobile and my service is so shotty with them that WiFi calling is the only way I can make phone calls most times. I am in Orlando and when the phone was under warranty it was a software issue and the a couple weeks out of warranty they tell me I need to purchase a new phone. My wife is having the same issue. Only she bought a new phone and it didn’t work so wtihin two weeks of having the new phone they replace it with a refurbished phone that also doesn’t work. Just received another non-working phone from T-mobile today. When we threatened to cancel the contract the T-mobile customer service person told us “Good Luck With That”. How can T-mobile be in business?

  • tprirep

    With how bad WiFi calling is on the SIII I actually thinnk that was a very wise move on Google’s part. I work in a retail store and every customer I talk with including co-workers the quality is horrible and pretty much not usable!

  • cactus

    Explain tmobile wi-fi calling enabled phone with Google Voice for dummies–so If I am in Europe or China with wifi access, I understand that I can dial a US number and the wifi contacts the tmobile tower in the us…but A couple people mentioned that they are using GV….my understanding was that it simple used your phone to make the call..what does using GV add to the wifi calling? Appreciate the responses. Sure its simple but rather than remain confused figured I’d ask..

  • Marc

    Bunk! I’ve got the 2nd gen G2 from t-mobile, has wi-fi calling. That has been the compelling reason for me to stay with t-mobile. I would have purchased the Nexus 4, but I have inadequate cell reception in my home. Bad idea t-mobile. If you could do it before you can do it again. Probably will cost them my monthly $$ as I’ll probably move on when necessary.

  • xmiro

    WiFi calling on T-Mobile is done by modifying the operating system I think, and using a different sim card, hence why you can’t get WiFi calling on this phone. Although maybe they should figure out how to do it via an app and let us download it separately.

  • Will the Nexus 4 work with a GBA sim? I have a T-Mobile GBA sim card and plan on cutting it down to a micro sim. My only question is will it work.

  • John

    Big fat DUH written all over this. Tmobile’s wifi calling requires implementation at the kernel level. It’s not just some voip app that can be installed from the play store. Clearly, any carrier modification to the OS kernel will NEVER be allowed on any pure google nexus device. I don’t get why people would even expect this…

  • justlikeadrug

    Im in the US from 2007 ..tmobil its the most lame operator on Earth !!!.. asks $200 on contract and $500 up-front for a smartphone that costs $349 unlocked!!!!!!!!! Don’t let them scam you! When i spoke with a costumer representative over the phone few years ago they even had no idea what video calling is and the people i spoke with 5 over the phone and 4 different stores in chicago ! They dont even have real 4g! they only clame to have one … Im sure that chick from the tv add will never got on the bike again if she knew what she was talking about .. no wonder noone europe want to get rid of them ..SHAME ON YOU HOW DO U SLEEP AT NIGHT !

    • philyew

      This might be a shock to you, but no carrier has “real 4G”. The “real 4G” standard requires the ability to do 100mbps mobile download. Current LTE deployments are not capable of delivering that and both Verizon and AT&T will need to upgrade their hardware and then deploy LTE-Advanced before “real 4G” is possible. Sprint are now deploying the right hardware, I believe, but certainly haven’t stepped up the software, while TM’s LTE deployment next year will be using the right hardware to do a software upgrade to LTE-Advanced.

      Don’t be fooled by the marketing hype. While every US carrier claims 4G capability, none actually has it according to the letter of the standard…and it’s not really any better anywhere else in the world. Unless something has changed in the last few weeks, there are no commercial “real 4G” deployments to be found anywhere.

  • bradsh

    deal killer

  • jerry

    I have survived the Hurricane in Northern NJ. We have no power and no TMO signal. It was nice to go to my cable company’s hotspot and make phone calls and get my email. Yes, there were a few hotspots that still work in the blackout… don’t ask me how. UMA Calling is a lifesaver. If this phone don’t have it, it’s a deal breaker. The older Nexus phones support it.

  • never used it , no complaint here

  • Sonny To

    Why can’t tmobile make wifi calling available as an app in google play? Wifi calling is the only way I can make calls at home. Tmobile isn’t known to have good coverage

    • philyew

      An app on its own can’t enable wifi calling. The capability on other devices requires files to be added/replaced in areas that normal applications cannot access.

      (a) You can’t do that on an unrooted phone

      (b) It’s doubtful that it’s possible to package a change like that into an app even when rooted, and

      (c) the whole point of the Nexus series is that the devices come with a standard Android build, and having a modification in the system directory would clearly cease to be a standard Android build.

  • Mike

    NOTE 2 all day ….LG =yuk

  • RyanFerg

    Unless you use GrooVe IP App

  • bmbrad720

    If you need WiFi calling use Kakao. You can text and call for free.

  • niididdy

    Boy it’s been so long since I commented on here! I’ve continued to be a reader…just haven’t posted. I’m start back again now! I got the GS III when it first came out and it’s the best phone I’ve ever owned. But I’m ready for my very first google nexus device. I love my updates, which almost seems close to non existent with manufacturers and careers…even so with delays etc. NOTHING will deter me from buying straight from google the Nexus 4 16GB. I’m also picking up the Nexus 10 as a nice compliment to the Nexus 4. One more week….

  • MuthaFuckinStephen

    I’m still getting one. Im pretty sure wifi calling is possible via rooting. Boy I love Android devices.

  • parinsan

    9to5Google and TalkAndroid are reporting that the Nexus4 will indeed support Wifi Calling citing the Nexus4 Tmobile Support site:

  • parinsan

    The following Nexus4 Tmobile Support document shows that Wifi calling will be available :

    • It doesn’t have it, it’s a generic manual.
