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?

Yes it has been. Can't find the source right now but Tmonews.com is where it was hottly discussed and proved to be right.

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.

[Q] Inspire 4g and 3g MicroCell?

Can anyone confirm that this will work with a microcell? I am thinking about picking one up, guy on craigslist has one for cheap. I am basically just looking to enhance my signal in the house, but also adding reliable 911 service in case of an emergency.
Thanks

Yeah, I have a Microcell. Works great with the Inspire.

not for data

Does the MicroCell require yet another monthly fee to ATT? Can it be used with a broadband connection only?

"AT&T 3G MicroCell acts like a mini cellular tower in your home or small business environment. It connects to AT&T's network via your existing broadband Internet service (such as U-verse, DSL or cable) and is designed to support up to four simultaneous users in a home or small business setting."
http://www.wireless.att.com/learn/why/3gmicrocell/

If you pay a monthly fee (I think $20?) then you get unlimited minutes while on your MicroCell.
if you just want the minutes you use on your MicroCell to be treated as minutes used up anywhere else (ie, come from your monthly or rollover bucket) then there's no monthly fee.

My 2 cents.
My AT&T Microcell works great.
It cost $150 + tax.
No monthly charges.
Microcell voice minutes subtract from you monthly minutes (but who ever uses those up?)
You can pay extra to get unlimited Microcell minutes (useless).
Use Wifi for data.
If your phone doesn't have Wifi get one that does.
If you don't have Wifi, get an access point.
Old non-3G phones don't work with it.
You can configure up to 10 phones to have access, no one else can use it.

My son called and complained about the horrible EDGE reception at our house (no 3G in my area, but a big enough city that there should be). When I got my first phone years ago, reception was great, but once they moved up to EDGE I think they lost the ability to use another companys tower a few hundred meters away; the reception sucked ever since, half the time I don't have a signal at all. He called up and complained; don't know all he said, but the woman actually gave us credit for that months bill (runs around $150) with the understanding that I would purchase a microcell, so it was essentialy free.
Works pretty good; sometimes it has an issue with staying connected, and if you lose the signal and lock on to EDGE, it won't switch back over until you either manualy switch over or you lose the EDGE signal and it connects back to the microcell. Switching back over is a matter of just toggling the airplane mode off then back on. It's not a perfect system, but at least I can make and recieve calls at my house now. I hated having to keep a landline just because my cell signal wouldn't work. AT&T works fine everywhere else for me (I'm a travel nurse, so I'm only home for a few weeks out of the year, though my son lives at my house). I was about ready to switch over to Verizon until they gave me that.

My Inspire sees and connects to my MicroCell much faster than my iPhone 4 ever did.

man...there is one listed around me at 30 bucks. That is cheap! see another at 50 but most seem to be around 100. I'm going to call my buddy tomorrow who never gets signal in his basement and tell him to pick this thing up.

It works fine for me as well. But I get better bandwidth using the local ATT tower on my rooted, H+ enabled device than I do the 3G MicroCell. Using the 4G from the tower (wifi turned off), I get 2MB download and 1.3MB upload. When the MicroCell is turned on, I get 429KB download and 279KB upload speeds. Luckily though, if I'm in range of the MicroCell, I'm also in range of my WiFi. I'd love to hear of ATT will be upgrading the MicroCell to 4G speeds.

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.

Got charged $150 by T-mobile for WiFi call roaming.....

Was in France, used T-mobile WiFi calling feature and got billed just like I haven't used it at all..... THIS IS NUTS....Is T-Mobile trying to rip me off or did WiFi calling not work on CM ROM. I obviously know how to use it and even showed my friend who by the way did NOT get charged.
So yes, WiFi calling icon showed its active and connected while I made the calls....

Was your phone in Airplane Mode?

I don't think WiFi calling works in air plane mode

If you turn your phone in airplane mode, then turn on WiFi, it should work.

Just call up t mobile. They usually sort those things out for you.

I did. They say they cannot guaranty free Wifi-calling roaming....and the only thing they can offer is $80 credit with 2-year contract extension.\
I am just too tired to argue.....it says on Tmobile website NO ROAMING CHARGES, I asked to see Terms and Condition for Wifi-calling where they dont guaranty it and rep says they dont have it.....
I have no proof that I used Wifi calling and all they see are my calls without any Wifi-calling.....

The Wi-Fi calling does not work in airplane mode... Skype, text plus work strictly in Wi-Fi with ap mode on. Wi-Fi calling requires a cell connection to register. I just finished a deployment in the middleast and used the Wi-Fi calling feature, no extra charges. I'm rooted using weapon gingerbread.

I know 110% that I was on active Wifi-Calling. Does this feature need some sort of activation besides the already included Wifi-Calling app ?

Lol you should say that it's a software issue that t mobile ignored and you expected the phone to function without extra charges.

Well, at least we all will know in case of travel abroad: either bring a US VPN account or do without.

oh well, i extended my contract and got my $80 back. i figured i am probably gonna get One S anyway, so now I dont have a choice and will be buying One S when it comes out since i am already under contract.

I don't have WiFi calling because I am not with T-Mobile. Instead, I use airplane mode with WiFi turned on and use Skype which gaurantees that there's no roaming charges. That will work for any phone which has WiFi and Skype anywhere in the world.

WiFi calling uses your plan's minutes, unless you strictly went WiFi with the Groove IP+Google Voice route. I'm not surprised they whooped you with an extravagant phone bill from you "roaming" internationally.

I've used WiFi calling in Australia, Brazil, Canada, and the Philippines. I've never got a single charge from T-Mobile.

thats how its supposed to be. i have NO idea what happened to me. i only see 2 reasons: 1. problem with custom ROM or 2. T-mobile has to actually enable Wifi-calling on their side in order to avoid roaming charges.
of course maybe its just a glitch in the system. after all how many people use this to avoid roaming fees....very few, so i really have ZERO proof.

One way to figure it out without costing you $$$ is to take your phone to T-Mobile and use one of their store's SIM cards to try out the setup you used for WiFi Calling. If you discover the cause for being charged while using WiFi Calling, post it here.

That's why I'm always careful to not enable any roaming with data, hits you hard. :/

my data and data roaming was disabled. < thats another lol story how i decided to do some web browsing in Switzerland and got billed about $70 bucks. i had no idea that 1MB of data could cost $15 bucks, while calls are very reasonably priced.
another word of advice while abroad, NEVER use pay phones in airport or hotels ! Use you Tmobile phone instead. Many if not most of those are scam businesses not controlled by any FCC

Talk and surf at the same time over 3g ?

can you talk and surf on photon q without using wifi or 4g access like the sgs 3 i think its S-evdo that allows this
anyone that has this phone already confirm this ?
TIA

Don't know about this 'S-evdo' thing, but none of the CDMA/EvDO phones I've ever had were able to do this. I just tried it on my Photon Q and still no.
It probably works on LTE, but I can't test that since Sprint doesn't have LTE coverage where I live yet. WiFi still operates fine.
Hope that helps!

Whats weird is that i tried this on my photon the other night and it didnt work. Tonight, i was able to make a call AND pull up the internet while on 3G. Connected to Airave if it matters. During the call the 3G icon never left like it used to do on all my other phones.

Don't trust the icon. lol
Edit: Just called a 1-800 number to test this and ran a speedtest.... I can confirm that 3G does work while in-call; 500kbps which is impossible over 1xRTT.

Evo lte can do it
And it depends if the towers have been upgraded for jt

Wonder why this wasnt pushed as a feature. I got over 2 MBits doing this connected to my Airave. I have noticed a slightly longer delay in voice when using data at same time. Could just be my imagination i guess.
Does this really have something to do with the tower or more to do with extra radios in the phone itself?

Maybe because if you're connected to one of these Airave things, you're near an internet connection and could probably just use wifi. Doesn't really seem like a very appealing feature.

What? I dont believe the Airave is what makes the voice / data at the same time possible. I simply stated the speed I got to show how well the simultaneous services work under great conditions.

So then it is possible just as long as the tower your phone is connected to has been upgraded to allow this and this phone does support it???

I think it only has to do with the phone itself. More than one radio in it is the deciding factor. Actually, I have my phone set on CDMA/LTE mode, I wonder if i set it to CDMA only if this would still work.
