UMA Wifi Calling

I hooked up my new MT4G to wifi and it prompted and notified me of wi-fi calling.
Take a look at the picture attached
Pretty sweet finally a android with wifi calling!!!
Edit: This is not uma

above
excellent, wrong forum
bg

Wrong sub forum

I'm gonna go against the grain and say right forum.
Wrong descriptor though, it's not uma.

Technically it's not uma because it doesn't hand off to.and from the tower like blackberry... But I'm equally excited.. Tested and confirmed on mine as well

Sorry for the wrong sub forum post. OOPS I forgot where I was.
I was unsure of the cellular handoff. Has it been confirmed that it doesn't hand off?

Please stop calling this UMA. It's not the same thing at all.
Wi-fi calling is a clever way to push people on to their own wifi infrastructure. Rather than continue to use cell tower bandwidth, you use your own broadband connection for both data and voice traffic. The best part (for them) is you still use your minutes.
Most people never bother setting up wifi on their phone, because they simply don't have to. The mobile network is available 24x7, and wifi eats battery life. Now, get to charge you *and* get you off their network at the same time.
Brilliant strategy, but I'll pass - I'm not paying T-Mobile to use my own bandwidth.

You would if you were somewhere you didn't have coverage. Or even better if you were out of the country and wanted to call back to a US number and only use your normal minutes and not pay for international roaming.

The app works great for me with crappy service in my house been waiting for it. Once you get close to the wifi range limit u get a pop-up warning you your call will be lost.

The only problem I had was whsn walking away from work or my house it would drop the call vs the hand off like the blackberrys uma calling feature.
I also think we are all aware this is not a true uma. I will try to edit my op to correct.

It is supposed to do mms sms calls as well as the usual internet and email.

This is a great feature, i'm just confused why they wouldn't build it to allow it to seamlessly handoff to cell towers.

That would b a hardware requirement and raise the cost.

I used WiFi overseas for calling on my BB, and TMo came after me with a bunch of international calling minutes anyway. So unless they have changed their policy - be careful.

Data Connection issues?

I am wondering if anyone else has experienced issues with their phone taking way to long to establish a connection when surfing the internet. Some times when I click a link it will take for ever and sometimes not connect at all, of course when it does establish the link it is blazing fast. Typically when it cannot establish a connection I will just put my phone into Airplane mode and then turn Airplane mode off and typically after that it is able to establish a connection.
Thanks.

my phone often goes from good 4g reception to just showing two or three bars with no connection type (never auto switches to 3g, occasionally switches to 1x). just now it went from 4g to no connection type, so i dialed *#*#4636#*#* and tried turning the radio off and on, tried changing the radio mode to LTE only, cdma prl auto, and a couple of the other choices and it never seems to make a difference (always poor connectivity, sometimes total data drops, sometimes while tethering and sometimes when just using the phone normally). could just be LTE tower work in many areas, but im looking forward to an upcoming software/firmware update from htc or verizon.

Sometimes when I lose connection, I just restart my phone and everything works again. Try that and see if it helps!

I run into that quite often... sometimes it clears up after 20 seconds, others I have to disable and re-enable the data connection. I'm strictly in a 3G area, and it's done it with LTE on and off, as well as stock ROM and my custom ROM.

Really? A $500 phone and you're ok with having to turn it off and on to maintain a data connection?
I've had several HTC phones, going all the way back to my WinMo phone, and this Thunderbolt has to be the worst HTC phone I've used to date.
On my second device, if I keep it, it'll only be to grandfather the unlimited 4G data plan.
Inconsistent data connections and force closes up the wazoo... Wow!

My dig wasn't at you, no offense meant buddy. I'm pretty much fed up with this device and will most likely return and cancel contract.
I've had issues with data since day one and I've never had so many force closes on one device.
This is Verizons flagship 4G device and it's a POS.
I've been on Android since G1, iterated thru the OS with each release thru to Gingerbread on my N1.
Verizon has a rocking 4G network, HTC released a crap phone that was delayed for several weeks. I would have thought that by the time they RTM'd it would have been fixed, or at least better than it is.

It's cool, I know what you mean but I'm liking the phone... Occasional reboots don't really bother me that much - this is probably because sprint wimax is nonexistent pretty much anywhere indoors and is the most unreliable network connection ever. the evo was a solid reliable device, but it was worthless because of the network and i canceled sprint to come to verizon for the thunderbolt. im happy with it despite a few annoyances. once i root and cm is released this phone/network combination will be untouchable.
i felt more comfortable using dialup and praying the phone wouldn't ring and disconnect me than i did using sprint wimax. their 3g is slower than dialup in a lot of areas at the moment, too.

This is driving me crazy also. My phone will constantly drop whatever connection it had (wifi, 3G or 4G) and just sit there with no data connection for a couple of minutes whereby I finally have to reset the radios and then wait while it cycles through 1X and then maybe 3G or 4G if I'm lucky. Or it just goes back to full cdma bars and no data connection. I don't have 5 minutes every time I want to check the internet or email to wait for the phone to reboot or reset radios or do whatever it's doing.
I had the EVO, and while the 4G wimax connection wasn't always stout, if you lost it you immediately grabbed a 3G connection that was solid. This delay/no data connection thing is making me think twice about switching to this phone. Love the 4G when it works, but it holds a connection way too infrequently for me to be useful, and I'm in LA where the service is supposed to be blanketed all the places I'm trying.

Will wifi calling work at the resort in Jamaica?

I've been trying to figure out a way to use my smarty phone keep in touch with my kids while in Jamaica this fall. Was hoping I could do a push to talk or walkie talkie app to talk to my kids via wifi. This on Metropcs. Now that I'm here at Tmobile and the G2X, will I be able to call home using the wifi calling via the resorts wifi? Will it work to make a call to the states?
Still really loving this phone!!

I don't see why not. I could call back home using it while in St. Maarten a couple months ago.

I haven't done this personally, you lucky SOB, but I've heard lots of reports that it will work as long as you have an active wifi connection.
I think it is pretty cool. I travel nationally and sometimes I don't get great service if at all but WiFi calling will come in very handy.. I also use it for work... *thumbs down*

@player911 said "you lucky SOB"
I know right...Couples resort Ocho Rios...420 all day everyday!
Yeah Mon!
I'm glad to hear I may be able to comminicate with home.

Yes, you can make and receive calls just like you were in the states via wifi calling. One of the neater things about being on Tmo

The walkies talkies work fine over , WIFI. No matter where You are.

Thanks for letting me know this....what resort? So the wifi is working but wifi calling isn't? Are there any settings you can check? Did you have a confirmed wifi connection when you tried? Not calling you stupid I promise, just would love some details. I have never even messed with wifi calling yet. I do appreciate you replying. Gives me time to research why it doesn't work and my options.

Have you tried rebooting? Once in a while I'll come home and my phone doesn't enable Wi-Fi Calling, even though it works most of the time, and rebooting fixes that.
The only other thing I can think of is signal strength; it won't enable Wi-Fi Calling unless you have quite a strong wifi signal, although it will hold it once started if the signal strength doesn't get too low.

Turning on my phone with wifi on there has been a few times I tried to use wifi calling in my home and it said I wasn't registered on the network yet. I had to turn off wifi and saw the 4g icon flashing then I turned wifi back on and the wifi calling would work.
I am not sure if T-Mobile will require you to register on the network first prior to using the wifi app. I am curious as I travel out of the country sometimes.

You do not get charged minutes if you are on an eligible plan.

I mean really, the only thing would be if you're in an area with crappy T-Mobile reception, you can connect to someone's wifi.

It also comes in handy when you're overseas. Last I heard you don't get charged international roaming if you're using wifi calling.

When the earthquake happened last week, all the mobile networks in NYC were jammed. However, Wi-Fi Calling let me get through, since it's routed over the Internet to T-Mobile instead of via the overcapacity cell towers!

Galaxy S4 missing calls, not receiving calls - Compromised solution

Symptom: I just upgrade from iphone 4s to Galaxy S4, after about a month use, I missed 4 calls from my friends. The phone did not ring at all, and there was no missed call in the log. This is a very serious problem. someone say she almost broke up with her bf just because of this, :laugh:
Solution:For now I found the solution is to turn off the LTE by go to setting=>Connections=>More networks=>Mobile networks=>Network mode and then choose "GSM/WCDMA". Then you will not miss a call.
Compromise: your data speed is reduced to 4G HSAP+. But if you have 200MB plan and only receive emails like me it does not matter(poor solution for people who has unlimited or 2gb+ data plan), plus by using 4G HSAP+ instead of 4G LTE you get better battary life.
Explaination: I lives in Pullman WA where we have LTE here. Some of my friends using a LTE capable phone (iphone 5, other GS4, nokia 920) also met this problem sometimes (this happens totally random or say I cannot conclude a situation when this will happen). The general idea is that LTE can only handle data transfer but not voicecalls (you can make a call with the LTE on and you will see that your phone swith from LTE to 4G), so if you are using the LTE network and your phone is connected to wifi (at this time your phone is using wifi data not LTE and then you are not connected to the tower at all, this is my guess, I am ME engineer not a communication engineer) and it's on sleep mode (these situations are my assumption) you may miss the phone call. But when you wake up your phone and ask your friends to make test call. you will receive the call.
If you read this post, many people with GS3 has this problem before:
forums.att.com/t5/Android-Discussion-and-Support/Samsung-Galaxy-S3-Not-Receiving-Calls-Phone-issue-or-Android/td-p/3270741
and with iphone 5:
forums.macrumors.com/showthread.php?t=1489651
and their solution is to turn off the LTE through a complicated process(we have such function build in the phone, :laugh,
I put this here to help people who has the same problem, but I also wish ATT can fix this problem ASAP because we are paying for LTE speed. So if you have the same problem with your LTE phone please leave a post here and this could arrise the attention.

Yes, they give me a new sim and my old sim stop working after they activate the new sim. But I put that new sim into the iphone 4s first before I put it into the GS4, Will this cause the problem? Do I need to ask them to issue me a new sim?

Probably not. If you got a new LTE sim then that should not be the problem.
