Why UMA Still Matters, Especially On Smartphones

I’ve often wondered why UMA doesn’t get more playing time in today’s T-Mobile world and, to be honest, it frustrates me. A service so simple, so powerful and yet seemingly avoided on T-Mobile smartphones, save for the Blackberry. I can’t wager as far as to say it’s a hardware problem, or a software problem that prevents T-Mobile and their partner manufacturers from getting this service up and running on Android, Windows or even Nokia smartphones. When I lived in my old house, it was a cell phone dead zone for everyone but AT&T. Verizon, nope. Sprint, not a chance. T-Mobile…well that didn’t work so well either but UMA was a dream come true. Not only did I not get stuck with the death star (AT&T) but it allowed me to use my phone inside any room, or outside, even on the driveway. It was like paradise had found me and I was living the dream. Remember the Nokia 6085? Oh yes, I sported that for a while, that was my home phone and my Pearl was my going out to impress people phone. I sim card swapped every day and I was perfectly fine with it, because I had my magenta inside my home and I was perfectly happy.

Nowadays, those looking or, more importantly, those needing UMA services are forced to skip out on every smartphone worth buying on T-Mobile. I’m not saying the Blackberry 9700 isn’t worth anything, it’s a perfectly awesome phone but Blackberry just isn’t the cup of tea for a large contingent of smartphone buyers anymore. Let me go on record as saying we’ve heard, on more than one occasion and from more than one source that T-Mobile will be bringing a UMA Android device to the masses this year. Of course, this is, like all things, merely rumor and speculation until we get something concrete and on paper. We’re holding out hope, but more importantly I’m ready to beg T-Mobile not to give up on this service, not to avoid its advantages in favor of trying to score points on the HSPA+ front.

I know it might be an image problem where T-Mobile doesn’t want to put a focus on a service that basically says “hey, we don’t have good enough coverage in your house but by using your broadband we can fill that gap.” Look the bottom line is I understand that, from a marketing perspective, it’s not a good look. With so much talk of 4G this, HSPA+ that, who wants to emphasize Wi-Fi? This feature isn’t something that makes T-Mobile look less effective; it makes them look more efficient and more likely to fulfill customer’s needs. Say what you want about Verizon’s impeccable marketing, they very well may be the most reliable carrier in America. That doesn’t make them the best carrier for everyone and we all know plenty of locations where Verizon works, T-mobile doesn’t and vice versa. UMA isn’t an end all be all problem and some people don’t want to consistently rely on a Wi-Fi connection for service and I get that, it’s not something you should have to rely on. However it’s also something you shouldn’t ignore because, frankly, what’s the difference between that and a Microcell? When push comes to shove they are both tools to increase signal capacity in a low signal area. The reality is that’s what matters to the consumer, the ability to make calls and reliably make them. If T-Mobile can provide an alternate method for customers who want to keep T-Mobile service, or lived in a dead zone for cell service like me, then why not do more to up sell this service.

The bottom line is I think T-Mobile is missing a golden opportunity with UMA and has ignored it for some time now. It came out with a lot of hoopla but died down quickly and whether or not that was due to poor marketing, poor implementation or just a stigma on needing to piggyback off a wifi connection to make a call is anyone’s guess. I think T-Mobile can handle both an HSPA+ rollout and a redoubled UMA service because what it’s really about is providing the customers with alternatives and selection. Why can’t I have both? I know HSPA+ is going to come to my area eventually, maybe by the end of the year or maybe in 2011 but it’ll come eventually. In the meantime, for those of you who still live in a house like I did why shouldn’t you have the option to enjoy the T-Mobile service you love on a wifi connection that’s readily available? Come on Magenta, give us our UMA!

    I’ve had T-Mobile UMA for three years and love it. I did not get it because I didn’t have a signal in my area, but I got it so I can make free calls from home with my cell phone. I still have it and do not want to give it up. I hope T-Mobile brings it back for other people. It’s a great service to have.

    • Yaniv C

      Its so much more than just that. I remember going to a wedding in St Maarten. Since we were pretty much “out of commission” no one thought of going to the local cell provider to pick up some GSM sims. Everyone was stuck for 4 days with NO PHONES.
      Since I had my Curve and the place we were staying at had free wifi around the whole complex, I was able to get UMA and call the states and receive calls with no problems. Totally amazing.

      • Pat

        I had a similar situation when I went to Ireland. My bank account had a couple of issues and with UMA I was able to call the US and not have to pay a thing. It was a life-saver.

      • J-Hop2o6

        Why doesn’t everyone Tweet @Tmobile_USA and tell them to push UMA again and put it on more smartphones since it very useful, especially out of the US and dead zone in your house.

      • Chino B

        @J-Hop2o6 that’s a great idea!!

    • pjs

      UMA was on Windows Mobile (T-Mobile Shadow 09) and Nokia e73 has UMA so that invalidates some of the article :)

      • Cassie

        No it doesn’t..simply left out the less popular phones goofy! And yes, I can say less popular because I worked smart phone tech care for T-Mobile…I got a call on a windows mobile phone every 3 or 4 days…everything else was Blackberry or sometimes Android. Never had a call on that Nokia or any other Nokia for that matter.

  • Jeff

    I’ll tell you what the problem is with UMA is. In area’s with spotty when the signal strength changes from 3 or 4 bars to no bars, like near the mountains, your phone switches back and forth from network to UMA and eventually you call will drop. So the solution is to put it on UMA only in these areas. However, if you have it UMA only when you walk out of your house and hop into the car and forget to turn it back to to radio/uma your SOL. I had it and it didn’t work for me.

    • tpavey

      So what you are saying is UMA is bad because it may lead to dropped calls or you forgetting to turn on wireless when the alternative is MORE dropped calls due to poor coverage in the area you need UMA?

  • franktronic

    There has been endless speculation on this subject but the only logical explanation posited so far is that it allows essentially free calling all over the world. That’s a lot of money that someone — not necessarily T-Mobile, but someone — could be missing out on.

    I used UMA for years and saw it work across BlackBerry, Nokia, and Samsung phones so it can’t possibly be a software or chipset issue keeping it from broader deployment. Somehow this issue comes down to money, I’m just not sure exactly how.

    UMA is the the MAIN reason I am still with Tmobile and I have been with them since 1997!. I do love the customer service and prices but they desperately need better smartphones with UMA included. Thanks for posting this and hopefully it will get Tmobile’s attention.

  • mikeeeee

    my ZIPCODE is 38221.

    there aint no fire in the air.

    i have 3 active lines, 2 UMA and one tmobile@home.

    i’ll stay grandfathered on this ’til they kick me off.

    the only thing i want is UMA/ANDROID.

    i carried around a KATALYST and a G-1 for well over a year.

    mash them together and watch it sell.

    what’s better than WIFI indoors and 3G outdoors?

    the name of the game is communicating aint it?

  • PathogenX

    It’s basically a ATT femtocell just like the cell this failed as well.

    • crimson230

      No, it’s definitely NOT the same as femtocell. With UMA you can jump on ANY free WiFi location worldwide and make/receive calls. The range and number of femtocells are only a small fraction of the available Wifi locations. Also, at least with at&t, your number has to be provisioned online for your phone to even be able to connect! How useless is that?

  • DavidinJax

    Your story is my story. The only cell phone carrier that works in my apartment is Verizon. I love T-mobile, I’ve been with them for over 7 years..
    Then the whole UMA thing happened, and my life changed!! I love UMA!! It’s the 75% reason why I still have my blackberry.
    Although, I am thinking a change is gonna come for me. Sadly I see Verizon in my near future. Even Sprint put a tower in my area so now my Sprint friends have a signal in my apartment and surrounding areas.

    WAIT!! I make free phone calls with UMA?? Why do I have an umlimited plan?!?!?!?!?!
    I didn’t know the calls were freeeee!!!! Wow :\

    (although changing my sim card when I get home isn’t such a bad idea)

  • Bob

    I was told by a T-Mobile rep. that the android 2.2 upgrade that is coming (when?) will have UMA built in for any android phone. He said when you are in a low signal area it will switch to wifi. I told him I have the original mt3g and he said it will be on there. Now, just when is that froyo update???

    • David

      That’s ummmm, ridiculous…it’s a hardware thing as well as software and the older phones don’t have the hardware. Simple, it won’t happen.

      • Bob

        All UMA does is encapsulate GSM packets inside TCP/IP packets over WiFi. It doesn’t require any “special” hardware to work. It doesn’t require a “special” router to work. For the T-Mobile implementation of UMA, you need a TMO account, a phone with UMA software on it, a WiFi router and an internet connection. A router with a few tweaks on it will help the phone battery life, but isn’t required.

        UMA (on phones that support UMA) does not require the $10/mo feature. All the $10/mo feature does is give you unlimited minutes over UMA.

      • mikeeeee


        has an ANDROID app ‘workaround’ but it aint so hot.

    • bryan

      That is mostly correct, the 2.2 update coming for the mytouch and mytouch slide will include a wifi calling app/capability but it is not UMA. The difference is that it will not be able to handoff calls from wifi to cell and back. The update should be out before the end of the summer (likely september) for both handsets according to out htc rep. Hopefully it will also be offered as a downloadable app for other handsets.

      I do think it is software that has prevented a UMA/ wifi calling capable Android handset yet, UMA is basically VOIP and Android did not originally support a full VOIP capability. That has changed but i dont remember what version of Android it changed in (it could even be 2.2).

  • JC

    I heard from a regional TMobile manager that UMA on Android is in testing and should be released later this year.

    As for UMA – gotta have it. I use it all over the world to make calls and avoid roaming charges.

  • Nate

    I have continued to purchase Blackberrys simply because they have UMA and are the only phones that work in our basement. I too am hoping for UMA/Android. It would make a nice September birthday present!

  • http://FatKatMusic.com A-RON

    I love the UMA service!! I live in a area where NO cell service from ANY compamy works but I do have internet and at home use a blackberry for service and than sim change to an andriod when I leave.

    So T-Mobile you have a GREAT service that already working and has been for years lets see the service on all if not most the smart phones!

    As from a hardware issues they make many programs that work over wifi (VPIP) for phones like the iPhone and androids why cant they make the UMA service part of the phone…

    Come on Tmo with the customer service!!

  • Biker84

    Rumor has it that T-Mobile is testing a 3g microcell, similar to what AT&T uses to help their indoor coverage problems. This is why they have been slowly doing away with UMA handsets. At least this is what I have been told certain T-Mobile employees….. Who knows if its true or not…..

  • Dennis

    “It came out with a lot of hoopla but died down quickly and whether or not that was due to poor marketing, poor implementation or …”

    I would say the same about the TMobile@Home service. Those of us that have it are rabid about it, it is a fantastic deal and a real carrier lockin in the right situation. But …. it’s gone now. As far as I’m concerned TMobile’s advertising department should be asking AT&T and Verizon for some kickbacks for the great job they’re (not) doing.

  • Noah

    UMA is the unsung hero of cellular services. I got it for the sake of traveling and also (initially) the $10 all-you-can-eat deal that is gone via “@Home”. Currently, my sister and her whole family swear by it simply because of a lack of signal.
    I don’t know that there would be a stigmatic effect on the service as per T-Mobile’s “reputation” for low-service if they offered it as an integrated service as opposed to their original concept – Pay-per-month. Most phones are capable of pretty darn good VOIP service these days and I would think that shoehorning it into UMA for Android, etc. wouldn’t be an issue. To offer this as a “value-added” service, an augmentation and a gift could help T-Mobile maintain its position as service-oriented, increase the perception of the service in general and continue to undercut expensive services like Verizon or the asinine AT&T MicroCell.
    All that said, they really do need to work on the switch-off. It was horrible on my BlackBerry.

  • the android

    The G1 Blaze will have UMA as well as a dual core 800mhz processor. A buddy of mine was testing it. If it didn’t have a hardware keyboard i would be all over it. Should be dropping mid to late September.

    • alex32

      nice cant wait. The g1 blaze/g2 is the phone i will be getting. The dealbreaker compared to the mytouch hd for me was the fact that this phone will have android 2.2 stock compared to the mytouch hd having that horrible expresso/mytouch skin.
      It has been more or less confirmed that itll have a 3.7 inch screen which is a bummer but I dont care. September needs to come already. Hopefully it launches from september 9 to 15. I cant wait any longer

    • bryan

      God i hope that processor spec is right. That will be the only thing that might have kept that from being my next phone. With Google’s recomended specs for the next version of android being 1Gig processor and 512Mb ram I would not buy a high end handset with less than those specs. If the processor is really dual core then sign me up now. The vision/blaze/whatever the final name will be is nice, processor was my only concern.

      • alex32

        processor is my concern as well. Something tells me the g2 blaze wont have a dual core, then again i dont mind if it has 1ghz processor. I do think its strange that itll have a 800 mhz processor..it gets me thinking why does it have a 800mhz processor when the rest has 1ghz? Then again it could also mean a dual core. So we’ll have to wait and find out.
        I am almost sure a dual core wont come out till 2011, but since the g2 is a google experienced phone like the g1..im sure google would want to make it special by hopefully adding a dual core (;
        In my opinion tmobile would have to start either advertising now or putting up some kind os news on this phone next week. the earlier the better..but who knows.tmobile is very unpredictable

      • bryan

        Our HTC rep stated that the vision/blaze processor was not a 1Gig processor. He said it was a custom chip so there is a possibility of a dual core chip. I did not even think to ask about dual core chipsets, since i was not expecting them to be available until closer to the end of the year or early 2011.. It did feel faster than both the Mytouch slide and the Vibrant, but that could also be from running a stock non skinned 2.2 rom. If the processor is not at least 1 Gig i will be very disapointed, since that will put it below the recomended specs for the next version of android.

    The only carrier that has coverage at my house is AT&T. I don’t live anywhere crazy… just a random black hole in the burbs. I want to stay with Tmobile but I want an Android phone that I can use on my wi-fi. My Blackberry is nice but it’s just not scratching the itch.

    When traveling to visit family in rural mountainous Arkansas I was the only person who could use my phone…. because it was UMA!

    I don’t get unlimited minutes on UMA. Calls still count against my plan. I don’t pay extra for t-mobile hotspot. You just have to be able to connect to an open wi-fi signal. So many people, even T-mobile reps, do not understand the difference of UMA calling, hotspot calling, and femtocell. I finally had to figure it out myself by just asking the question of the t-mobile rep trying to sell hotspot.. did I have to use their router and sign up for hotspot? NO!

    UMA calling transfers automatically. I do not have to change any settings in my phone. I walk into my house, it changes to UMA. I leave and get into Tmobile coverage a couple of blocks from here and it changes to 3G or Edge.

    Adding UMA to an Android phone WITH proper knowledge by their sales/customer service people and marketing would be a slam dunk for T-Mobile. Why wouldn’t a company want to say.. “Yeah, we’ve got you covered. Even in your cold-war era bunker of basement.” I mean… come on.. that’s just awesome..

    BRING IT!!! Thank you tmonews… keep this in the forefront!!!

  • jwal636

    Our Motorolla rep told us the Charm will be UMA. Anyone else hear the same?

  • RWWackoStu

    I would not be with TMO if it was not for UMA. My town is a TMO dead zone. The only thing around me is Sprint and the Deathstar. IF UMA goes, so do I. I’ll take my 6 year grandfathered plan and walk. Thats how important it is.

  • Bill

    I am a Blackberry fanatic and have stuck with T-Mo because of UMA. The 9700 works greats with it BTW! (So did the 8120 and 8900)

  • Chris

    Right there with you fellas. I was UMA for years and decided to take a chance and abandon the BB. I love my new Vibrant but having to walk to a window just to make a call gets old.
    No chance of it getting better due to geography. Dang you Earth!

  • MW

    I actually had purchased the T-Mobile wiresless router to enable this service in my house so I would not have to use my minutes (that was their selling point). Little did I know that they would not add this feature to the G1 or any other Android phone. This is a place that disappoints me with T-Mobile, if you have a service put some phones in place to use the service. Unfortunately they continue this foolishness with HSPA+. All they have is HSPA+ compatible phone. What good is an HSPA+ compatible phone, I am paying top dollar for my phones and I expect full use of it. I don’t want an HSPA+ compatible phone, I want a HSPA+ phone and UMA. Come on T-Mobile pulling for you, if you have a service have phones ready for the service at the time that the service is first available!

  • ManoloDF

    UMA is the best and the reason I am with T-Mobile. When the Nokia E73 came out I bought 2, one for my mom and one for my brother since it finally had UMA. It really stumps me that it is not in every smartphone out there, android, WP7 etc. It should be essential, especially to TMO and with all their business accounts, the blackberries just dont do it for me. Another thing they should implement is how to enable UMA ONLY mode on all UMA phones, blackberries do a great job of this but for example Nokia does not. I want more UMA news!

  • Memphis1979

    We strayed away from UMA, because no other carriers were promoting it. Its hard to get phone manufacturers to include chip sets that no one else wants.

  • http://robert.aitchison.org Robert Aitchison

    Screw UMA, it always seemed like a half-assed “solution” to spotty coverage.

    Should get into microcells which will work with any phone.

    • bryan

      I dont see how microcells are much better, instead of buying a handset you have to buy a microcell. Additionally, microcells limit how many handsets can access them at once (not an issue for UMA/wifi). You still have to have highspeed internet access to use it so you probably already have a wifi router at least.
      Im not saying microcells are worse, or that they are any better, they are just different.

      I would like to see both as an option, microcells for low end phones without wifi and UMA/ wifi calling for smartphones since they already have wifi. Give the customer the choice of which solution works best for them.

    • Jeff

      Robert, exactly! It seems to be working for these guys, but where i needed it worked, but like you said it was half-assed!

      Just focus on better coverage and you don’t need it.

  • NiiDiddy

    Loved UMA when I had my Blackberry Curve however many couple yrs ago before Android. It was great—I had the feature that allowed me to be able to free/unlimited called over the UMA.

    Note people: fact that you have UMA doesn’t mean you have unlimited talk through UMA. If they bring it back, T-Mobile should also bring back the $10/mo add on for unlimited talk.

  • Ludda

    To the best of my knowlege, most T-Mobile phones are already have Wi-Fi. I’ve been using Wi-Fi for the past for 2 years with 3 differen phones (Samsung T339, Shadow, & Cliq) and I won’t purchase a phone without it from now on. If this is something that T-Mobile is going to decrease then I will be very dissapointed because that is a required feature when making a decision on a new phone purchase. Even if you have good service at home, the internet is much faster than 3G, and most times it’s more convenient to use your phone then going on your computer to look something up real quick. My school is in a dead zone (very small because I get full bars across the street) but we have plenty of Wi-Fi connections to choose from so I would be helpless without it.

  • sat

    So vote on the Android UMA ticket:


    And there are companies that have created working android UMA software stacks:


  • ItsMichaelNotMike

    I was one of the first people to sign up for HotSpot at Home. Back then it was $10 monthly, a great deal for us on limited minutes.

    I remember using the phone (I think it was a Curve) at Starbucks and it was super cool the way the phone seamlessly switched from WiFi to my cell plan. What was really cool is that any call STARTED at a public WiFi (UMA) remained free and unlimited after leaving the public WiFi area.

    Even though the plan was $10, I cancelled it once going to unlimited talk since it was no longer an issue, keeping track of minutes to avoid overage charges.

    As I recall, the reason HotSpot failed is: 1) people did not understand HOW the service worked, no matter how simple the TV ads made it look; 2) there were simply too many competing services, where people at home could use those services, such as Skype, Vonage and other VOIP (internet calling); and 3) in line with not understanding how the service worked, people either did not have the required broadband cable modem or they were unwilling to get it from a cable provider.

    IMHO #3 above is what killed HotSpot @ Home. Having to “do a deal” with one’s local cable provider so to get HotSpot to work was as toxic as telling people to get the iPhone they had to sign up with AT&T.

    The savings to a T-Mobile customer became foggy when one had to calculate in the cost of cable broadband service into the mix. If one did not have a cable modem it then became $50 monthly to enjoy HotSpot, not the advertised $10.

    And of course this did not pencil out if one compared the rates with Skype and Vonage (for international calls).

    Yes, for those who did not get a T-Mobile cell phone signal this was a great alternative, especially if one could then leave the “dead zone” UMA connection then seamlessly continue a call via regular cell service. But IMHO there’s too few of those customers to justify the service.

    Hotspot was like FedEx’s “Zap Mail” in the late eighties. Zap Mail was simply a fax machine used via Fed Ex offices. One would go to a Fed Ex office, the clerk would fax a document to the FedEx office where you wanted the document delivered, and FedEx would deliver the document in a FedEx envelope.

    Zap Mail lasted about a year because soon everyone had fax machines rendering the service moot.

    HotSpot is the same because there’s so many alternatives. And a UMA phone was hard for anyone except the geeks to understand. (And there were not enough geeks to justify the expense of providing the service.) For example, I suspect that setting up the router required a lot of calls to T-Mobile tech support. Having live people available to answer questions is very expensive.

  • maritza

    100% agreed! My home is a deadzone for all cell phone signals. My BB Bold works beautifully on my wifi, but I wish I had more options :( I pray the UMA/Android rumors are true!

  • Dave

    We have dropped our landline, and now rely totally on our TMO phones. As we have good cell coverage at home, my love for UMA has nothing to do with bad coverage at my house.

    I travel internationally, nearly monthly, and when at home, many business calls are overseas. I switched to BB rather than Android about 15 months ago. My initial reason was that I could pay an extra $19.95/month for unlimited BB messaging services overseas. That beats $20/MB for data charges when roaming internationally.

    It was a pleasant surprise to find out the BB had UMA. I can make free international calls from home in the US, and make free calls when overseas, provided of course I have a WiFi connection. It sure beats firing up my laptop and getting Skype started, or paying anywhere from $0.49/minute to $4.99/minute. (Yes, I know minutes are deducted from my plan, so the calls are not techincally ‘free’.)

  • http://soapboxuniverse.blogspot.com/?spref=gb K. Ray

    I considered the hotspot at home for for a while. I did not have internet. By the time I installed it Magenta gave me unlimited for $60 bucks and made it not revilement. We will see what happens after all the fall things happen. I’m curious to see what HTC has in store for Sept.

  • Jake

    As a customer, I love UMA. Better reception, and access to my pool of minutes from anywhere in the world so long as I have wifi access.

    From T-Mobile’s perspective, UMA has become a liability for a few reasons.

    Reason number one: The technical parameters required to add UMA make it another loop for phone manufacturers to jump through if they want to deal with T-Mobile. In this new age of smartphone competition, customers are quick to jump ship to other carriers for the latest and greatest, and T-Mobile’s business priority is to get their customers to stay put by making sure there are no barriers to negotiating with handset manufacturers. Simply put, T-Mobile can’t risk placing an added burden on manufacturers that UMA technology potentially requires.

    Reason number two: T-Mobile marketed their UMA sales pitch around the benefit of “unlimited free calls when on wifi” instead of the advantage of better reception in more places. Now that they are pushing their unlimited talk plans, touting UMA plans with unlimited talking will take a bite out of their most profitable talk plans. IN theory they could still offer UMA on future handsets without supporting unlimited UMA talking, but then UMA has a weaker marketing pitch as simply a “better reception” technology. Unsavvy customers would start to wonder, why does my phone need a feature to help reception? Is T-Mobile’s reception bad?

    The reasons mentioned above provide a window into the complexity of balancing the needs of the business with the needs of the customer.

    i think there’s a little consensus here.


  • SPyla

    if t-mobile does not come with UMA on Android before Verizon comes with android world phone, I am switching to Verizon.

  • JustLoseFocus

    I love UMA, it does what I need it to do, have great coverage at home for me. I started using it when I had my Blackberry Curve 8900 and now I use a 9700 and my friends are jealous of that one feature T-Mobile offers to its capable UMA phones. If the iPhone had it and Android phones had it, people would be happy. I thinks its very very useful, depends on the phone users needs.

    whoa… do i hear crickets on this page, or what?!

  • penguin

    motorola charm has UMA

    its android/uma

    • mingkee

      May you elablorate?
      I don’t see “wifi calling” on spec.

  • Tony

    Would UMA work on t-mobile’s pre-paid service using the bold 9700, or any UMA phone? I recently switched to simple mobile, but when I had my t-mobile blackberry, UMA worked world wide with no issues and basically giving me free US calls over wifi while overseas. So this could be a great tip for travelers. Oh, and add google voice, and you get affordable international calls too!

    Great post, by the way!

    The new UMA service for Android won’t be an app you’ll be able to download from the Market Place.

    Instead, it will be a FOTA update pushed to select devices.

    The good news is that UMA functionality will be enabled on Android phones that don’t have the specific hardware chip installed.

    The bad news is that this version of UMA will only work while connected to a WiFi hotspot which means the call will not hand off to the PCS/AWS network (or vice versa) like it does on current BlackBerry devices. So if you start a call over UMA on your Android and you go outside the call will drop.

    Should be ready later this fall per my local Sales Engineer. That is ALL I KNOW. No specific dates, links or which OS version will be compatible with the service.

      Will nexus one or Behold II qualify for UMA for Android?
      I can put Behold II on main line and let nexus one runs as mobile hotspot on webconnect.

      UMA is primarily about how to perform handoffs between GSM and VOIP so something that doesn’t support this simply isn’t UMA. That doesn’t mean that it wouldn’t be great to have but please don’t represent this as UMA.

      UMA doesn’t require specific hardware other than both a GSM radio and a WiFi radio. It does require the vendor to implement a UNC (UMA Network Controller) which basically handles all the signaling which tells the backend network that a switch is being made between access methods. From the UNC back to the rest of the carrier equipment the WiFi connection looks like a regular GSM connection which is part of what makes it *relatively* simple to implement UMA. So basically the handset talks to the UNC to ask for a transfer from GSM and then initiates a GSM session over TCP to talk to the UNC. The UNC just looks like any other tower to the providers network.

      If you want to understand the standard you can get information at:

    Please add UMA on Mytouch HD or MyTouch slide HD.
    Don’t T-Mobile know this is pretty critical for those who are in bad reception area?
    I am waiting and waiting for UMA Android phone, so I can utilize my nexus one to use webconnect, and use the UMA on mobile hotspot built in nexus one.
    Here is the scheme how I want to utilize “mobile UMA”
    3G->nexus one (mobile hotspot)->UMA over wifi->UMA Android phone
    This is pretty useful for me as I am in some areas where I have to put the phone close to the window to get reception and wifi isn’t available, this scheme will save my day.

    ok UMA.

    Its better than FemToCell.. why? If you have a UMA phone, u dont have to buy additional equipment that requires additional monthly fees. Period.

    UMA on Android.
    T-Mobile has promised to release a UMA APP on android for Tmobile Phones. It is NOT a HARDWARE problem, just a software problem. They HAVE NOT made good on the promise yet, but still keep promising, so i think it will come shortly.. 2.2 perhaps?

    The Mytouch3g has been promised 2.2. Its in the last android magazine. If they are going to print it, they are going to deliver it. Point blank. Rumors are one thing, printing it in the “official android magazine” for Tmobile is another.

    UMA is great at getting service where you have no signal but WiFi. BUT it still counts against your minutes. Everyone that thinks it doesnt, just didnt pay attention. Weather it counts as international or not if your out of the USA i dont know, but in the USA, it is MINUTES,not FREE. :) It connects you back to the Tmobile service from your ISP and it very much tags your minute usage… so dont think you are going to be on a 500 minute plan and call your VZW buddy for 1k extra minutes and not see a funny bill.

    UMA is GREAT as a network alternative for those that recieve weak signal at home or work but have WiFi. And its really sad that its not on all devices by now on Tmo’s or anyone elses network.

    • bryan

      T-Mobile has never made any official statements promising a UMA/wifi calling app for Android. There have been rumors before but there have been no official statements promising a UMA/wifi calling app. It is very likely coming soon but even that has not had official confirmation.
      There was a $10/month unlimited UMA calling feature but it was not required to use UMA only if you wanted unlimited calls over WiFi, so some people on here may very well have unlimited UMA calling if the kept the feature.

  • akil

    main reason why they prob wont bring UMA to T-mobile especially android because of features like Hotspot WIFI, if you really can make free calls via UMA then i could just use my nexus one’s for hot spot and connect off of it and make free calls

  • Cassie

    I now live in an apartment where ATT and TMobile both get pretty much NOTTA in signal. Because of a move I had to switch from my Motorola Cliq to a Blackberry 8520. I don’t mind Blackberry (by the way the “search” option in the message folder is awesome and I just discovered it last night), I would still much rather have an Android device. I bought my fiance the Vibrant because the lack of signal doesn’t bother him as much and he lovesss watching tv on it at work. I have less patience for dropped calls than him. I want an awesome Android phone with UMA that’s what I want, I love T-Mobile and I’m sure plenty of customers are thinking the same thing as me.

  • Cassie

    And one more thing. Please correct me if I’m wrong but don’t you have to have the “unlimited wifi calling” feature in order to make “unlimited wifi calls”? Otherwise they deduct out of your regular bucket. I do believe that feature is still grandfathered as of October of 2009. So some of you may have it, but other users like myself do not. So bottom line if you have the feature it is unlimited, if not minutes comes out of your bucket…Like I said correct me if I’m wrong. Oh how cheap my rate plan would be if I could have that cheap little feature back! tehehe lol


    This is one of the few things I do miss from by black berry. It was a great feature to have when you didn’t have cell service, but you did have WiFi connection. It would be nice to see it rolled out to the android line of phones from T-Mobile.

  • shackk

    Originally when I signed up for the @Home service it came with unlimited UMA calling that does not come out of your bucket minutes. I can still confirm that if you have the feature grandfathered in, your minutes are still unlimited both @Home and UMA. If not UMA minutes are pulled from your bucket allotment. @Home service is no longer available.

    I think personally the @Home service was a no brainer. $10 all you can talk VOIP service just makes sense for a home phone. Couple that with the unconditional forwarding minutes and you have an extremely cheap option all while having a separate number. Take the router with you and you have your @home service wherever you have an internet connection. Even internationally, your number goes with you and free. I can see where Tmo lost money on this but it certainly could have been marketed differently and easily competed with other VOIP options. As for UMA, while it may not be a perfect solution it works and works well and if you jumped in at the beginning you can’t beat the unlimited minutes it came with.

    I have also seen ATT branded blackberry’s use UMA which leads me to believe that it is not hardware but a software limitation and hoping Android will have this sooner rather than later.
