Wi-Fi Calling Coming To The Galaxy S II, Amaze 4G On November 13th

From the moment the Galaxy S II and HTC Amaze 4G hit store shelves there was a lot of unanswered questions about Wi-Fi calling. Was it available or not available? Was it locked on the phone requiring an update to unlock? Was Wi-Fi calling no longer coming pre-installed on Android devices? As it turns out, the capability is there but the feature isn’t. The good news is we’ve got a solid answer on when exactly Wi-Fi calling will be ready for both of these premiere T-Mobile devices: November 13th.

We’re not 100% sure as to reason why Wi-Fi calling wasn’t enabled from the start but we can say with a measure of certainty that a specialized SIM card is required to ensure Wi-Fi calling works post November 13th. We should preface this and say that in order for this feature to work, you’ll likely have already used the SIM card that came with your Galaxy S II or Amaze 4G.  If you pre-ordered or purchased in store you need to ensure that your phone has the “GBA SIM card” which came with the device at the time of ordering. If not, I’m sure a quick trip to a T-Mobile retail location can rectify the problem. You don’t have to rush however as anytime between now and November 12th would be good.

Assuming your phone is ready with the “GBA SIM card,” come November 13th you’ll be good-to-go with Wi-Fi calling on both the Galaxy S II and the HTC Amaze 4G. So there you have it, while it’s been a little bit of a mystery regarding Wi-Fi calling, we have our answer and we do like answers.

    Oh yeah!…that’s what’s up!

  • Fchambers

    The Sim cards have to have the code tm9177. It’s on the side with the actual chip, and it will be a different wifi calling, not the same as with the original Galaxy.

  • KWB

    Got my Amaze via instore purchase.  But the SIM card looks exactly like the one that I have in my Bold 9700. The salesman said that I couldn’t use my current SIM from the BB in the new Amaze (got that one back), but not sure if he used the one that came with the phone (assume he did).

  • Oce

    My new GSII comes tomorrow!!  Hey David, do you or anybody know what’s going to be different about the new wifi calling feature?  I hope it’s more like the uma calling available on the Blackberrys.  This would really help me out at work.  The uma feature works with our wireless network but the wifi calling doesn’t.

    Is there anything else that T-Mobile limits based on the version of SIM?

      I learned a while ago that you can’t swap a T-Mo SIM from a phone into a tablet. It makes no sense to me… I have a full unlimited data SIM for my phone, but the tablet tells me I need a tablet-approved SIM. Data should be data. Very annoying.

        Is this an unlocked tablet? or did it come from T-Mobile?

  • How ’bout some WiFi calling for the HD7 T-Mobile?

  • Wilma Flintstone

    I’m wondering about this one.  Hopefully the Nexus comes to Tmobile because alot of you want it pretty badly but it seems kinda grim as of now with Verizon opting out of the GS2 for this (But we all know Nexus started on Tmobile but so did Android and you see who made Android Popular – Verizon unfortunately).  We shall see though tonight at the respected times of the Live show.  Here’s hoping for the Prime to be on Tmo because it is an awesomely spec’d phone.   The design can use some updating though.

    I wonder if that’s y my g2x wifi calling doesn’t work. Because my old sim card work but after changing it it doesn’t work.

  • daghost

    Question #1 answered.  Thanks David.  Question #2 and perhaps the most important question: has Tmobile disabled the free tethering on these and/or future phones?  David, or anyone else, can you answer that question?  I havent received a definitive answer on that yet.  Thanks.

    • tmo rep

      Tethering was never free, it’s 14.99 a month.  A lot of people have been able to use the feature for free.  Some people have got the upsell message.  If you have it for free, enjoy it.  I’m sure we will be cracking down more and more as time passes. 

      • tmo rep

        I meant it was never free when android 2.2 dropped.

        • daghost

          i heard of that charge before but i have been using it for free on my g2x which came with froyo.  Even when i did the update to gingerbread, it didn’t affect it.

        • Anonymous

          Ive been using it for free too… Dont see why I should pay extra for it. It shouldnt cost more if i view facebook on my phone or on my computer… data is data.

        • Josh Gordon

          i haven’t been able to use tethering for free on the s2. i activated the $14.99 plan, an it started working right away.

      the biggest problem here is that you cannot use the phones data while teathering

    If you look up gba and Sim cards you’ll see together they make for a secure authentication process. While its not UMA hardware like blackberries this can definitely change things up a bit. I always assumed the gba was going to be used somehow with the nfc chip and Isis.

      You are correct. I read a few “reviews” of the GS2 on the T-mobile web site too! That really shook my confidence in buying this based on the reviewers who had used the “new” UMA!

      • Josh Gordon

        There’s a difference between wifi calling via third party apps (Skype, google voice) and wifi calling for for tmobiles own network. The former was possible, the latter not. But it seams come Nov 13, both will.  

    • Evos469

      I’m not trolling. I’ve been using wifi calling on my GSII since I bought it last week but I’m on the old school unlimited plan.

    • Ryan

      Well, the early software for the Amaze did have WiFi calling, which was removed in a software update.  My Amaze came with the updated software, so no WiFi Calling for me.  So some people who had the Amaze may have had WiFi calling working, but I’m very skeptical of SGS2 claims of WiFi calling.  My gut tells me they didn’t do my test of putting the phone in airplane mode (disabling all radios), then turning on just wifi, and then making a call.  Methinks that would not have worked.

    I’m glad..wifi calling its very convenient.. Hey can the amaze save internet video (not youtube videos) to the internal memory like the vibrant??

  • Jack

    To anyone on here asking about the HD7 wifi calling…..its not going to happen at this point, and T-Mobile is not the one to blame there. Microsoft did not include it in Windows phone 7.

    As for the wifi calling…after the 13th, there will be two versions of wifi calling. Still no handover for Android, but you won’t really see the difference. Just diff sim. The new sims are backwards compatiable with the old version. You do need the new sim for the GSII and amaze at this point. Plus, those new sims can store I think 508 contacts now, and each contact has 3# and an email.

      when i got my DEFY last november i used my old sim card. worked ok for a little while. then it dint so i switched to the new one that came with it and it works fine.

      if the merge goes through and they dump wifi calling they lose me.

      i aint buying no new device ’til all the dust settles from the ‘merge’.

  • If you use an older sim card with this phone, you’ll find that it will get VERY hot and the battery life will drain FAST! …   I found this out while updating my sim card because the manual says you need the new sim card for wifi :) ….  Even though I need to wait till November glad I got the newer sim card! :) 

  • ssq

    Anyone know if the wifi calling would work on a different carrier (in Canada)? Or would I have to wait for Nov 13? Still waiting for my phone to get delivered…

    • TmoRep

      you can use it to make FREE calls back to the US while roaming n any country. you just have to make sure you have the “WiFi calling is active” icon in the notification bar. and of course you have to wait until its enabled on the sgs2

  • Ryan

    In addition to using the new SIM, according to the quick guide that came with my Amaze, for WiFi calling to work, you need to register your home address on your t-mobile.com account.  Even though I have T-Mobile@Home and had my home address register for that, I had no registered address for my cell number.

  • Josh Gordon

    Thanks a bunch for the clarification, David! Was just about to return the phone tomorrow before the 14-day remorse period ends, and you save the day. Hmm, if only Samsung and T-mobile would learn something from you about communicating with clients. Now there’s a thought. 

    • Glad to help Josh!

      • DC

        Ditto here.  I have always been really happy with T-Mobile’s customer service, but after being assured that wi-fi calling was in there and active; I was very disappointed.  Even after showing them in the manual that the feature is documented, but the phone didn’t have the menu options, they still insisted that it was there.  It’s always encouraging when I know more than the sales people.  I travel overseas a lot and the wi-fi calling is a huge $$$ saver and like with Josh, a dealbreaker if it weren’t to be available soon.

    I received my two Amaze 4G phones today. Will WiFi calling just “work” on Nov 13th or will I have to run some type of update? For some reason we have very low signal in our home so we are counting on having this feature.

    Will we be able to receive calls over WiFi as well? Thanks.

  • Will this also allow sending SMS through wifi as well?

      Nope.

    guess there pulling the wool over our eyes again.  VZ its x to switch to the lesser of 4 evils. thanks for the lies Tmo

    • T-Mobile didn’t lie, we had this intel over almost a month ago. Perhaps the date changed.

    I have a MT4G and still waiting for a OTA Gingerbread update.

    • Guest

      If you don’t receive your update OTA, you can bring your device to a T-Mobile corporate location to get the update.

      • Biancakensington

        Not true. I’ve called or went into four stores and they either haven’t heard of doing the update or can’t because…… (insert excuse).

        • Skeems

          Because it is an ota update. You think the rep at the T-Mo store has some kind of magic little update button that they don’t want to share with you or something?

        • Mysupra97tt

          We don’t have the tools or resources to do updates for customers in the stores.  For some reason, customer care tells customers to come in and we will be able to update their phone…….. 

    • Rudy Ramirez

      I am a Tmobile RSA and you should  be able to go into a corporate store and get the update.  My store has been doing updates since late August.  If you go on Tmobile.com and look up stores near your area, you will know if you are looking at a corporate store if there is a 4 digit Store ID number.  Call them and make sure they have the SD card.  And make sure they remove your SIM card before doing the update.. because having the SIM card in the phone while updating can cause much problems.

  • Sweetnbeefy

    It seems awful strange that they would release an update on a sunday. Where did this date come from?

  • Brian Richards

    Tmonews.com, you need to explain what happened here. You’re credibility is taking a hit here. Big time. I kept this phone because I trusted you. You got some ‘splainin to do here.

    • So let me get this right? You’re mad at us for providing a date that didn’t happen? This date was never official and this is the nature of leaks and updates. T-Mobile never promised this, never acknowledged this and never advised us on this so you’re mad at us because the date didn’t happen. You shouldn’t be ungrateful for receiving information early and then forgetting how possible it is that information might not pan out. We’re right more often than we’re wrong so I don’t think our credibility will suffer at all because of this.

      This happens.

      • Vyas

        I hear Tmobile will have a new phone that can brew coffee on your drive in to the office… that coming from some random person has little meaning but with you giving definitive dates an actual date stated does give you a little more credibility.

      • Sam M

        David, I hope you dont speak like that and think your representing ANYONE. A voice like yours is better off silenced …Perminantly!

        • I don’t represent anyone. However, people need to direct their anger and their frustration in the right direction. Blaming me for trying to help isn’t helpful. You wouldn’t like it if people made direct accusations your way, so try not to stand on some soapbox telling me I’m a bad person for trying to explain myself.

    Tmobile never “officially” stated that NOV 13th was going to be the date for updates.  I’m telling friends to avoid the Amaze and SG2 for now, if they think they really want the WiFi Calling feature.

    • Bndehart

      Yes, they did say officially that Nov 13th was the release date for this to work. I confirmed it through several company reps…..

  • Anonymous

    I spoke to T-Mobile customer care, they said the GS2 is definitely getting wifi calling however there is no date actually available for the feature. The only information they could find was that there will be a small software update allowing wifi calling and it will be IMS based not UMA or GAN based. Everything will be OTA. Also in case your wondering if you have the right SIM card, on the back where the gold contacts are it will have “TM9177” printed on it. I also verified this info with a retail store manager who’s yet to steer me wrong in the 6yrs I’ve had T-Mobile. I guess its either root and force the old app on or just wait…

  • Went to the store today (which showed me an email stating nov 13th for the update) and all they could tell me was that it was pushed back.  The let me return the SGS2 even though I had it for 32 days and waived all the fees.  I switched back to by BB bold while deciding what to do.  Got home just looked on Tmobile.com and the SGS2 and the AMAZE are NOW LISTED AS WIFI CALLING PHONES!…  guess I go back tomorrow and buy it again if anyone can confirm wifi calling working on it

    Strange, I’m on a trip to Germany as soon as landed I got a pop up message on the Amaze. The message was something like…. “You must have the latest SIM card from your TMobile Deale or WiFI calling wont work”.  So this was on the 13th and I thought wahoo I am in!  But I still don’t see any wifi calling.  My dealer assured me this was the right sim card.  I cant recreate the message it was not as a text it seemed to come from the phone as a pop up.  So at least I think I can maybe verify that there is sort of a feature coming.  Does anyone know where I might look to find the feature on the off chance it is activated on my phone ?

    • Billy

      To all peeps, snap a sceen shot with your digital camera, or a friends mobile that next time a screen pops up like this.  That way you can share it with everyone later.

    I bought the galaxy s 2 yesterday with a new sim card. Very upsetting. Was hoping for this feature

  • Billy

    Why isn’t Tmobile simply using the old working version of the WiFi Calling app on their new mobiles?

    What happened to the good old process of releasing UPDATES?  Like it is done for; Tmobile Mall app, Google Maps app, Gmail app and many other apps.  Tmobile can work out all their self-induced WiFi Calling app provisioning bugs later.

    Tmobile Products Team must have made the provisioning process of the WiFi Calling app so fragmented, that developers can’t debug it.  Not only is Tmobiles Team provisioning a working app, but a provisioned SIM, on a already fragmented OS.

    “WiFi Calling?  Yeah it has that feature.  Its coming soon. 
    Date?  We can’t give you a date, but we’ll still state that feature as currently available to make us look good.”

  • Hunguyen56

    This one was a given, but we can’t help but love it when it has been officially confirmed. The Samsung Galaxy S2 has been officially confirmed by Samsung UK to receive the Android Ice Cream Sandwich 4.0 update, although there was no dates mentioned, apart from the promise that they will keep us posted.We had previously reported on a rumored list of devices that were scheduled to receive the Ice Cream Sandwich 4.0 update, and the Samsung Galaxy S2 was among them. We’re not sure about the fate of the other devices, but then again the devices listed are some of Samsung’s latest products, so it’s not a stretch to imagine that they would be eligible for the update as well.Reply

  • Navid G

    I spoke to both Samsung Galaxy S technical support and T-mobile technical support on the phone, both mentioned that there will no update coming soon and it is really disappointing for me because I can’t use my phone at home at all…. I really loved this feature and I think I should go back to my BB… :(

    What does WiFi calling look like on the Amaze?  In other words how do I know if I have it or not.  As I described earlier when I went to Germany last week a message came up about wifi calling and requiring a special SIM card.  When I explore on the phone.  Settings, Call, then scroll to the bottom there is a group called “internet call settings” and the Accounts (for setting up SIP accounts), and then a check box to when to use or not to use internet calling.

    Is this the same as WiFi Calling since I understand it to based on SIP ?   Or is this just a generic SIP/VOICE client bundled with Android ?

    I checked randomly with some work colleagues and they all have the same settings available to them.

    I asked my TMO sales rep and he said just go to MyTmobile and setup a SIP account to get the settings (of course there is no such feature that is active that I can find).
