[Q] Is it possible to use data on the phone while on a voice call?

Long time AT&T customer probably switching to Sprint, been eyeing the Epic..
If I get a voice call, is it possible (if I'm using a BT headset or speakerphone) to fire up a web browser on it and use that while I'm in-call? To look things up, or whatever?
If it can't do that, are there any other Sprint phones that can (EVO, for example?)
Thanks!

if i remember right, you can use data and voice only when you are connected onto 4G and WIFI, but not 3G. i have not tested this out yet to confirm but i remember reading that somewhere if i read it right. i also came from att (iphone) and being able to use data (3G) and voice at the same time was a major plus. ill have to try it out though later on my epic.

Yes u can use data while on a call only if you are on WiFi or 4g. Tested and verified.

Well, drat. Thanks fellas. Not that I do that very often, but it does come in handy. I checked and EVO "suffers" from the same problem.
Again, thanks, that's handy to know.

Its a cdma limitation, not a device one. Both sprint and verizon have this issue.

Some might say it is a "limitation", however is it the reason why cdma networks do not suffer from dropped calls like gsm networks do.
For more information, you can check out this rather lengthy post about why cdma is better than gsm.

yeah, i experience the same thing. it's becoming pretty much a deal breaker for me, as often i am on the phone for an hour or more and am trying to look things up at the same time. no joy. plus the abysmal battery life has me glad that i am still in the 30 day window ?; i like the phone a lot otherwise. wish i could get it for ATT. i have never had problems with their service, and would love to be able to talk and surf at the same time.

On 3g only voice.
On 4g voice n data simultaneous

[Q] T-Mobile Wi-Fi calling app

Now that the update for the G2 is out in the wild, enabling tethering/hotspot and wi-fi calling....I was wondering if it would be possible to rip the Wi-fi calling app off the phone and use it on the Nexus One.

Give the dev some time, they will have something for us by the end of next week.
I feel like this is a slap in the face. I am a little teed off at Tmo for this.

After reading more about it I doubt it's worth the time. It still uses your minutes while calling via wifi. Seems silly that t-mo would use my Comcast internet connection and still charge me for it.

Yes, it would suck coyote balls if it still uses your minutes while calling via wifi (except for those with unlimited minutes).
I absolutely cannot wait for the new whitespace to be filled with "superwifi" so we can all end this cellular carrier Kim Jong-Il madness.

I heard from a T-mobile employee that there is some discussion on internal corporate forums about bringing WiFi calling to T-Mobile 3G versions of the phone through Google. It will absolutely use your minutes (I don't see why they would change this), and will most likely be a while before we see it pushed (if at all).
I am sure there will be an .apk leaked as soon as the new myTouch launches.

In theory, because your comcast connection is only the air interface and the last mile backhaul, the call still gets routed over T-Mobile's phone network.
In reality, the air interface (which uses limited and expensive spectrum) and the last-mile backhaul is the most expensive part of a wireless network. So, no, they shouldn't charge you a full minute for calling on wifi. Maybe 0.1 "plan minutes" per minute of wifi calling would be fair, but would probably confuse old and stupid people.
However, the simplistic theoretical argument is what you'd get if you asked T-Mobile.

Honestly, I don't understand why people are so 'peeved' that "WiFi Calling" with TMO:
#1. It isn't out for the N1 yet.
#2. Uses your existing minutes/plan.
For the people who are grandfathered under the @Home UMA plans, it's probably still unlimited.
The majority of people who are hanging onto their BlackBerry and Nokia handsets with UMA are the ones collectively holding their breaths, including myself with a BB 9700.
If you compare with the other carriers and the way they solved "coverage" issues with femtocells, T-Mobile's solution is the most elegant and inexpensive. Are you going to carry your femtocell to a public WiFi hotspot and find an ethernet cord, power, and a clear window so the femtocell can get a GPS lock to make sure you're in the United States so it'll allow you to use the femtocell?
There's nothing like being able to make a 'normal' call, SMS, MMS, etc. (i.e. Non-Skype) where:
#1. Someone with a Verizon, AT&T or Sprint handset has no coverage.
#2. Being at a public WiFi hotspot outside of the United States (i.e. Europe, Asia, etc.) where your phone has UMA/WiFi Calling, SMS, MMS, etc. access and billing as if you're in the U.S. without paying outrageous Int'l roaming or purchasing a pre-paid SIM-card for the country you're in.
You guys have no idea...

agreed, it will be nice to actually be able to use my minutes

I just want to be able to call back home when I am overseas without extra fees

People that need this service dont give a rip if it uses minutes. I barely get enough coverage in my condo to send a text message (with ANY carrier). At this point I'd be willing to let it cost me double minutes. That's right I said it.
Also, as noted above, its the shiz for international calling. When we go to Mexico, I take my old BB curve so I can avoid the international rate shaft.

Wait... if I'm overseas and have wifi, I can call back to the U.S. using the app and ONLY be charged my minutes?!

Hold on there partner. I'm only speaking from experience with UMA and Mexico to US. They may have closed this loophole with the change from UMA to Wifi calling *shrug* idk.
On the other hand, it very well could be identical and they only changed the name. That would be ideal, as it worked perfectly before... just nobody knew what a UMA was

From what I've seen so far, I'm guessing it's UMA-Lite (GAN). The only functionality that's missing is the seemless hand-off from WiFi to a GSM tower when you leave a WiFi area. The call would just drop instead of being properly handed off to the nearest tower.
I doubt TMO would treat UMA-Lite any different from how they handle existing UMA handsets.
Cheers,
Kermee

T-mobile really needs to push this feature onto all their phones and start advertising it. It will really give them a leg up on the competition, and people will stop associating tmobile as being the cheap carrier with lousy reception.

Project Fi Users

Any Project Fi user? How is it working out?
Sent from my HTC6525LVW using Tapatalk

It's dope.

Yup. Very happy.

Totally satisfied!

It's awesome!

More than anything I'm happy with the bill. I think mine was $43.xx last month, I'm signed up for 5GB at $70 total. Spent the last year on AT&T Post Paid with a MiFi also on the account at 115ish a month for 15GB. Prior to that I was on AT&T Straight Talk for years.
To be honest, the service is so-so. T-Mobile is T-Mobile, the building penetration sucks, its as mediocre as it was when I got off it in 2011. Sprint does provide better building penetration but the service is slower. I'm often frustrated with Fi's lack of attempt at switching from T-Mo to Sprint or vice-versa. I have Fi-Spy installed and can easily plug in the dialer codes to switch, but why it doesn't do this more proactively is beyond me. Even with the auto switch dialer coder plugged in and a reboot, it rarely switches quickly once a drop in signal is experienced with the carrier in use. The nerd in me thinks its cool to plug in the dialer codes, the normal me is beginning to find it inconvenient. Speeds aren't spectacular, I think that's possibly a function of being in South Louisiana. The carriers invest here last most likely because of the overall poverty of the populous and the gamble that the they can just wait till the network is destroyed by a hurricane and rebuild it with insurance money.
My gut feeling is I'll wait to see if the 6.0.1 release (whenever I finally get it) will make T-Mo work better with the possibility of Band 12. If its not better soon I'll probably switch back to AT&T Straight Talk. AT&T just works everywhere I have been in the US for the last 4 or 5 years. I never have the negative experience I hear people complain about on big blue. The Straight Talk option makes the cost negligible. Although the good ole days of Straight Talk "discount" service cards being sold online for 30ish dollars seems to be gone.
Cellular service is a commodity, while I impress myself with the nerd factor of an aggregated cellular carrier like Google Fi, I just lack the patience to endure the carriers its running on. Struggling with bad or slow service is no longer acceptable with the flexibility of porting numbers to other carriers. $40ish dollars is cheap, but for 50 I could be on Straight Talk on AT&T and not worry about any of the semantics.
...but I did like the Lego kit Google sent me!

What about calling/texting over wifi? The initial reason I decided not to go with Project Fi was for the reasons you stated-- didn't love the carriers that support it. But the more I think about it, the more intrigued I am. I just switched from AT&T to Verizon and I am hardly using any cell data. I'm at wifi at home, wifi at work, and many places that I go. Project Fi is becoming more appealing for the ability of being able to call/text pretty much anywhere over wifi and not have to worry so much about how good the cell signal is. Plus the idea of auto connecting to open wifi hotspots and securing the connection over a VPN tunnel sounds pretty cool as well.
On another note, I don't have any first hand experience with Tmobile but 6.0.1 should help a lot with cell service in buildings if they have band 12 in your area. The geek in you should just flash the factory images instead of waiting for the OTA

I'm very satisfied with my experience so far. My only complaint, a small one at best, would be there is no way to prefer WiFi calling over cellular like with Tmobile.

It's been solid for me. Not just at home, but a number of the approved hotspots as well when I'm out. And I like that these connections are VPN'd.

Data usage
I was thinking of going to Project Fi myself and got the invite already. However, I check my data status usage and it's about 4gb or more per month. And I am counting only the usage not being over wifi. I understand that Project Fi switch automatically over wifi if available so you won't use Data over the air as much. However, I'm with the family plan with 15GB and Data carry over next month on AT&T network. If I'm by myself, I would switch over to Project Fi in a heart beat but with family member, I can't. Just my 2 cents thought.

I have the exact opposite experience, I rarely get auto connected to hot-spots and when I do they're total garbage. Not just in Louisiana, but in large metros I've traveled to in since getting the service. I think only one held the VPN tunnel indicated by the key icon for long enough to do anything.

What I do love about the service is the ability to use Hangouts on all my devices and in the web browser and text & MMS from it. I think if I went back to Straight Talk I'd probably leave the number with Google Voice which traditionally I've done the opposite and took the number to the carrier and just had a miscellaneous GV number.
I have had problems with call quality over data. Mainly at my house which is AT&T U-Verse, and to top it off Fi does not seem to realize it and will not switch off to cellular when the call quality dissipates. I've literally had to run out my front door into the middle of my street if I'm mid call so it will switch to cellular. Its either this or attempt to fumble the phone and turn off WiFi. My neighbors probably are suspicious of my mid street calls :laugh:. Again, this is a function of AT&T U-verse having 18mb down at my house. Might switch my internet to cable next month to help with the abysmal ISP speeds with U-verse.
Again, don't expect the phone to just start connecting to tons of VPN'ed Google Certified WiFi networks. You'll be disappointed. I was in large metros all up and down the east coast in Nov and again, this may have happened once in each large city. You're going to be looking for the same old Starbucks and misc WiFi networks to make calls if you're really hoping to find WiFi networks in the wild for calling. I have a free Boingo plan through Amex Plat and it helps give availability to more networks than I had access to before. But its not enough that I wouldn't be worried about cell service.
Fingers crossed on 6.0.1... back in the old days I would have downloaded the image the second it was out and flashed it. As I get older and find myself making more excuses for not getting stuff done I rarely want to spend non existent free time diving into roms or any of that. I just want the phone to work and the service to work. Its a long way from chopping up Blackberry OS installers with different features from different Telcos or my first Android phone being a Sprint Touch Pro 2 launching into Android from Windows Mobile. Getting old (or boring) I guess!

Works great here. Except MMS over hangouts looks like garbage. I would love to use hangouts over my other devices with my Project Fi number, but I send to many picture messages. Anyone else have MMS hangouts quality problems?

Are you referencing the picture quality of the photos sent? Does it look bad both in Hangouts and also in the receiver's MMS?

Its decent, but I can see why people leave back to Tmobile. I am on WIFI most of the day and yet I manage to use 1.5-2GB per month, I cant imaging using Fi without WIFI. There is no VoLTE an no proper Band 12 implementation. Support is not that great, most replies are copy/paste BS. The whole service is just not as reliable as Tmobile. I pay about $40 bucks for Fi......Tmobile would have been only $50 but everything works 100%, you get som free music and vid streaming, and data falls back to free Edge.
I am gonna stick for a while longer....They said some updates are coming to service in next few month but I call BS on this. Fi team seems to be lying alot about the service and misrepresents it in their advertisement.

Weird... I have been on T-Mobile since the days of my RAZR v300 up until just recently. In fact, I still have it on my Moto X. Nothing about it is as good as Fi has been. Granted it is not for folks that are burning through a lot of data, but I have never gone over a Gig, so it's great for me.
Looking at the two phones side by side right now, the TM phone is on HSPA with 4 asu, and the Fi is LTE with 23 asu.

I have Tmobile LTE and VoLTE everywhere pretty much and it switches to Sprint for no reason, I even get Sprint 3G in some places due to bugs. On top of it Tmobile band 12 is not implemented correctly so you end up missing calls and there is no VoLTE support at all. I am not even sure if Tmobile carrier aggression is working on Project Fi
I've been having issues on Project Fi since June, including some spotty roaming in Europe where Tmobile got 5 bars of LTE (capped to 128kbps). Then been dealing with carrier auto switching for over a month now....looks like it just started working with latest Fi app and Android 6.0.1. They also know about all the roaming issues and that Fi doesnt like to connect to roaming providers, thats why they seem to include manual switching in Fi app now so people dont end up with dead phones overseas
They are also kind of lying about equal coverage to Tmo and Sprint....its not equal, at least not yet, lying about 120+ countries where wifi-calling is supported....also bs, real list is around 90-95 countries (not a big deal, but they refuse to fix it)
I switched from Tmobile because I though I will get 100% Tmobile coverage + addition of Sprint with seamless switching (been very buggy) I also need that 256kbps roaming speeds since its double of what Tmobile is offering. Lower bill was just a bonus.....dont really care since its like 10-15 bucks difference

Dunno what to tell you; have only been on it since 11/16, but so far it has been great on my 6P.

When I read these comments I wonder how many people were already T-Mobile or Sprint customers and used to so-so coverage and speeds already. Compared in AT&T and Verizon, you're getting what you pay for. Just calling a spade a spade as a long time AT&T customer and a really really long ago T-Mobile and Sprint customer.
It's exactly what they said it was, a beta service. If you want a cheap 5GB of LTE data that works everywhere, get a AT&T Straight Talk sim. If you really think you only use a gig and live in a large metro with a good economy (face it, T-Mobile and Sprint upgrade their carrier equipment metros with better economic conditions first) then you'll be in heaven.
Don't really care about the international, I just buy a sim locally whenever I go overseas. But for the price, if it works, it's a nice feature.

HTC U11 AT&T support and collection

this is going to be an AT&T specific collection thread for this carrier specific stuff like VVM and try to make wifi calling work, also users can ask any questions related to AT&T and I will try to answer them and hopefully other users can help to.
HTC lying about AT&T "compatibility"
U11 does not support VoLTE on AT&T
U11 does not support WiFi-Calling on AT&T
U11 does not support Video Call on AT&T
U11 does not support Integrated Visual Voicemail on messages app like it use to on HTC One M7, M8 & M9, you need the stand alone app which is crap...
the phone works for calls data LTE works MMS haven't test yet I don't use them....

Any comment from AT&T on any of this? We know HTC's saying it works.

Haha, AT&T never comments on these things.. and it won't work.. I have and unlocked GS8 and it don't work there either.. so no way in #[email protected] it will work on HTC..

Argh... This sucks. I'm in an area where coverage quality has dropped significantly, and I spend a lot of time in a building where almost no signal gets through from any provider. Wifi calling and texting has become a lot more important for me for that reason. I can get by without the extra features, but it's tough now what I've had them (currently using an S7 edge and Note 5).I guess that leaves me with no option but Samsung or LG (and all of the provider bloatware).

Don't activate the U11 on AT&T, once their computer "knows" you have an uncertified device you lose LTE data and are forced onto HSPA+!
Does anyone know an APN setting that will reactivate LTE?

no band 30 guys. http://www.htc.com/us/smartphones/htc-u11/

Not a fair critisim for HTC. Even if the phone is capable like my non-AT&T S8, if the phone does not have the AT&T logo on it they will not allow these features. So complain about AT&T like I do.

I'm on at&t and I'm getting full LTE with zero issues.

See if you still have LTE during a call. The LTE icon should go away and if you go into about phone and then network, it'll most likely say HSPA. The problem is we're not getting services like VoLTE and wifi calling. In normal cases, HSPA speeds should be manageable considering the average phone call won't be very long and there's wifi nearly everywhere now. This is just bad for those in areas with poor reception. I've been doing ok with the whole issue since I never really noticed much of a difference with HD voice and I'm usually always somewhere with wifi.
My question is what did they do differently with the U11 than the 10. We never had any of these issues with the 10 being unlocked and not certified and all that bs

The importance for me & probably for many others on getting VoLTE is that I do technical support on my phone and trouble shooting while on a call takes to much time most of the time, that being said if I don't have the option to make phone calls on VoLTE means internet speeds while on a call is crap.... I really don't care about HD call clarity as far as I can here the other person, but the internet speed while on a call it is important to me the faster I can browse the faster I can provide technical support

Having a weird issue with my U11 on AT&T. I randomly lose all signal for no reason then takes a good 30 seconds for it to connect again.
It has happened at least a couple times a week mid phone call which is really obnoxious. I have seen it happen a few times when I am just browsing through my phone not on a call so I know its not just a calling issue, and I am sure it has happened multiple times when I am not looking at my phone at all and I don't notice.
Anyone else had this issue? An issue with AT&T and can be fixed by a firmware update? Or am I alone and need to RMA?

I know this thread is old, but can't we use the ATT RUU if you do what you need to do? We used to be able to go back and forth, at least that's what I did with both my M7 and M8. If you really need those features, that's what I would do.

WiFi Calling on AT&T

I have looked thru thread after thread for days and cannot seem to enable WiFi calling on my OnePlus 5 on the AT&T network, Does anyone have a clue?

I switched from AT&T to T-Mobile when I got my OnePlus, so I can't say for sure, but I believe AT&T limits WiFi-Calling to certain devices, and even then, only the AT&T variants of those. (Mostly newer and from big name brands e.g. Apple, Samsung, HTC, LG). Since to my knowledge even an unlocked Galaxy s8 won't have WiFi calling on AT&T, it is unlikely that any OnePlus device will ever have that ability.

Yes, I remember reading you can NOT do Wi-Fi calling on att with bring your own device.

Le Pro3 is the only device that is BYOD and works on AT&T I believe.

Just another reason TMobile is the real deal

Yeah, or any of their mvno's!
I was with family today in Anaheim, a highly populated, very modern city I mean Disneyland is there.
My dad has AT&T, I have mint sim (a t mobile mvno) I had near 70-80db signal, he was bouncing between 120 and up.. Had no signal whatsoever for extended periods of time. And with their low band frequency purchase, it's only getting better. It's anecdotal evidence, but still..
While I don't think t mobile offers the best network, I strongly feel they are going to get there in a couple years should they keep this up..

I'm wondering about WiFi texting can the oneplus 5 do it? Also I noticed when in connected to WiFi I can't send any texts.

Att does not allow the 1+5, albeight the technology is there, to do VoWifi or VoLte. They reserve those features for devices solely purchased from Att, ie Only branded devices. If the Le eco does work it out of the box, that's awesome. Don't tell Att that, lol. I got into a huge argument with Att NatCs and filed troubleshooting tickets only to be told, sorry, since it wasn't purchased directly, no work. I have since made the move to TMobile. Im in NJ as a reference. And to be honest, I find the voice quality vastly better to what I had with Att, with hd voice too. I've hit some spots with little to no coverage, usually at a friend's house but my VoWifi kicks in and I have service once again with no issues.

Many retail/unlock mobiles have "Wifi Calling" function but not any menu entry to enable , The APP can check the hidden function and enable it if can use.

Interesting app. But I'm not sure it works.
I install it, on my un-rooted OnePlus 5, then run it - hey! there's a convincing looking setting, for wifi - and so I activate it. But everytime I return to the app, the setting is 'off' again. Does that mean the setting doesn't 'stick' and my phone (running on AT&T) cannot actually use wifi?
Plus, it looks to me as though the app has to remain running (although there's a setting to not display the notification icon, it doesn't seem to 'stick' either).
Ultimately, I cannot seem to get my phone to actually make a wifi call. For this reason, I'm skeptical this app is able to enable wifi calling, on the AT&T network.

I just called ATT.
I want to upgrade to the 5 and i need it to call over wifi as most of the time i'm in a rural situation with no coverage.
The ATT tech support said there would be no problem.

I hate to say it, but they lied (unless there's been a drastic change as-of-late).
Even if you can get them to provision your 5T, it'll only "stick" for a minute or so, and then revert.
AT&T is somewhat "famous" for their lack of BYOD (non-branded) WiFi call/text support. The exception is iOS devices, and a couple of "certified" Android phones; I think the HTC 10 (or maybe it was the 9) was an example, you can probably count these on one hand.

I call At&T today. No changes so far.

AT&T has an issue like this forever, as they do not wish to give that option to all. That is like a drop in profits, and drop in latency and lags. Anyways, too long to explain, but the gist is, they will have loss if they allow full coverage (at least loss on journal entries)..
