No voice and data at the same time unless you have 4G coverage?

Tell me there is a way to get voice and data at the same time on the Evo with 3g. If not, I'm taking this beast back.

Nope, that's always been a limitation with 3g. You cannot do both on Sprint's 3G CDMA network. Same for VZW.

I thought everybody knew sprint and verizon can't do that.
And being able to have voice ONLY with 4G has been talked about since the first day EVO was announced.

you can with WIFI on

I'm still lost as to why this is a deal breaker. I have needed that functionality only a handful of times over the last many years.
Some people really buy into the hype that at&t has been pushing these last few months

Wow, you just need to settle down. Having Data and voice at the same time isn't that important.

I just came from AT&T and I can count the number of times I have needed that feature. Most of the times has been when I am on a call and need to look for a phone number in maps or something like that.

same, if it comes down to it i'll just call whomever back.
i'm experiencing MUCH faster data (20-30% speed improvement over [email protected] in my area). so it's a worthwhile trade off for me.

I'm going to keep it for 28 days and see how it works out. I surf the web a lot while on conference calls. Also use it to look something up while talking. Typically, when I need it, I really need it.

I can't say I've ever needed that feature. My only Q for those with the phone, is the reconnect (to data) very fast? I'm assuming it's probably instantaneous.
I had a (long ago) Windows Mobile phone that had this slight inconvenience, only issue was that it took about 15 seconds to get a data connection again.

This is the only reason that I have ever heard that makes any sense...but of course when I'm on a conference call I am also usually at my computer.
There are not many people in your exact situation (conference calls away from desk), so really this is a slight inconvenience for 99% of people.

The ONLY time this has bothered me is when im tethering and i get a phone call or text and even then it only really affected me when I was video chatting with someone or another form of stream. The fact that it goes off when I get a text momentarily is more annoying than the phone call one though, because I tend to get many more texts than phone calls. If i'm on a phone call, I don't need to be tethering anyways generally.

It's also not exactly hard to test...make a phone call, then watch for the 3G symbol at the top of the screen.

It really depends on the person. I used it all time (i am sure we can find these exact points in another thread) but the EVO is well worth the sacrifice for me.
Used it today on my EVO as a matter of fact, I was in WiFi country needless to say

Sim. voice and data is really handy. Ever heard of Bluetooth. Browse the web and talk pretty easily. I can't say it is a deal breaker for me, but with no Wimax ( I refuse to call it 4G as it is not actual 4G) in my area their 3G speeds suck ass. AT&T I get 3.5mb down and 1.5 up. I tested on the Evo at Sprint store and was getting 900 down 900 up. Phone seemed pretty nice but don't think I want to ever go back to a CDMA carrier ever again.

I am LOVING the wifi calling!

That OTA update came just in the nick of time. I pushed it myself after I read about how to do it and still hadn't received the update. I left for Manila on Friday the 12th and have been loving the wifi calling here!! It has been a life saver in terms of paying for international calling. There is zero lag and the call sounds just as good as if I were on the network in the states. I can't really imagine a use for it while in the country since it still takes minutes, but I guess if you are in an area without TMobile but yet still has a wifi connection with a fast enough speed to carry the call, then it could be useful. I just don't know where that place is... All I can tell you is that it has been working amazingly well in the Philippians and I have been able to make and receive calls without interruption all week. My colleagues who have needed to pack an extra phone with international calling abilities have been absolutely green with envy as I'm still able to do business easily in the office without needing to be on a landline or paying extra to use my cell phone in the hotel. What a great innovation!!! Even texting has worked just as if I were still in the states. Everybody I call and text have had a hard time remembering that I'm out of the country since it is still not totally normal to be receiving calls and texts from the same US number even though I'm abroad.
Anyway, I thought I'd share. I tried it while I was in the states, but didn't know if the clarity or quality of the call was influenced by being near the TMobile network anyway. I can tell you for sure that it is a great thing with no downside. You do need more than just a wifi signal though. If the signal isn't strong enough then the phone won't register to the TMobile network and it won't work. Oddly enough, when it says the signal isn't strong enough to make calls, they still come in just fine. Maybe just a couple bugs to work out, but this has definitely made me glad I went with TMobile and not Sprint when I was shopping for a new Android.

Are you sure you're not still paying for international calling? I thought T-Mo was going to charge you.
As for "getting an international phone", the G2 probably could have been unlocked (barring S-OFF issues) to work with the GSM there just fine.
I just took my G1 to Australia after getting the unlock code from T-Mo, and it worked great there, 3G with an Australian SIM.

I remember someone on this forum confirming that if you use Wi-Fi calling, your phone is treated as though it's roaming in the states, which makes it extremely useful for those who commute internationally, like the OP.

Does wifi calling/texting count as data charge (becouse if it does, I'll be able to text for free anywhere there is wifi)

WiFi Calling feature uses plan minutes and plan txt messages... there are no extra charges unless you go over your limit

I was unaware it used plan minutes. Sounds pointless now unless I have bad signal in the house

Sent from my T-Mobile G2 using XDA App

Yeah, unless you just don't get a good signal in your house, there isn't much point to the wifi calling since it still uses your plan minutes. From here it works just like I'm in my office at home. I can call and text local numbers without having to dial any other weird country codes or anything. And people at home don't even need to know I'm out of the country since they just call my number and my phone rings just like normal.
Typically I have just used skype to call for free computer to computer since using it to call a phone number costs money. But now I can use the wifi and that is so much better! However, my hotel doesn't allow the phone to register with Tmobile, so some servers are going to put the kabosh on using this type of thing. I'm just wondering if it would work from the plane when I'm flying domestically and have the wifi available to me... FCC regulations prohibit using a phone during flight even if you are connected to wifi, so it doesn't really matter I guess.

The texting still counts as texting and not as a data charge. So it basically just uses whatever you already have on your plan. If you are out of text messages or minutes, then you will get charged for going over just like usual. I've got an unlimited plan for all that, so it isn't something I really keep track of.

I'm sure it could have been, but that is why I'm glad the wifi calling update came when it did. It saved me the trouble of needing to do it. Anytime I've been away from the office where I haven't had a wifi signal to attach to has been times when I don't really want to talk on the phone anyway. Especially here... I really don't want people seeing me with a G2 in my hand when it is a pretty lusted after phone here. Everything is uber cheap here, but I was at a less than legitimate item mall yesterday and they had a G2 in the same case as an iPad. I can get a 32GB ipad for less than a G2 here.

mods close thread!

fix does not work.

Is that force roaming to Vz? Maybe you started getting spotty Sprint ownwd EVDO coverage. Forcing 3g only could be putting you on Vz towers.

Doesn't EVDO Only disable voice calls?

This would also be a good way to save battery without losing all data connectivity.
3G/EVDO uses a lot of power. If you switch this setting to CDMA only you will force the phone to only use 1x. The data rates will be slower, but acceptable enough for most notifications and light things like facebook.
CDMA - 2G/1X Slower Data greater battery life
EVDO - 3G/EVDO Higher speed data, battery hog.

Hybrid OR CDMA only are the only options you should choose here folks.
CDMA only WILL produce battery life savings though. Your data will be slower then molasses rolling uphill in December BUT it will be sufficient for emails.
It's a very nice find either way just on that fact alone. Back in the motorola days this was a very popular battery saver mod. Disabling EVDO and forcing it to always be 1X.

hehe.... you are correct sir... going back to old ****ty service again so i can get phone calls

The EVDO radio and CDMA radio are two different radios I believe.
When you put EVDO only you're probably seeing JUST your 3G signal which might appear stronger.
CDMA only you're seeing just your 1x/voice/sms signal.
Hybrid the signal bars I'm sure just average the two out...
That's how I "think!" it works... could be way wrong.

Well at least i tried since sprint is dragging their heels. We need a new radio and quick.

I wouldn't be surprised if a new PRL fixes this... seems to be area specific, I have great signal for the most part...

Also, fixxer, I know you've been having horrid battery life. I'm sure the low signal is causing this as the lower the signal the more power the radio is going to be given to try and maintain the signal.
Try CDMA only and use WiFi whenever you can (also be sure to set WiFi sleep policy to never). 1x uses significantly less power then 3G... although it's to slow to be downloading big apps or loading really complex web pages, it would however be great for general notifications. Give it a shot and let me know if it helps your battery at all!

Could be a prl but i still think it needs a radio. This phone is set to wcdma when it should be cdma auto prl. Hopefully we get a fix or ota soon. My battery is better today since i flashed a stock rom and kernel. Not great but better.

I gave the CDMA-only option a shot, no incoming phone calls at all. Switched instead to EVDO only, and calls seems to be coming through better in an area where I had maybe 50% success rate for incoming calls when running unmodified. I'll leave it here for awhile, so I know when someone is actually trying to call me.
This is horribly frustrating, I suffered with poor AT&T service for years for the iPhone and never thought I'd be wishing I hadn't changed carriers. I could maybe justify the shoddy call coverage if data was at least fast, but it's not. I'm giving this another week, and going for a return and possibly switching carriers again.

CDMA only setting for calls/texts paired with 4G for data seems to work pretty well.
Since EVDO only mode seems to prevent receiving calls.
True test will be when I get home, 1930's brick building that has been raising hell with calls.

Most likely VoLTE...

Longer battery?!

It's VoLTE. Or, simultaneous Voice and Data as was missing from the device at launch with the promise to be fixed with an update by the end of the year.
I'm curious, though, if it counts towards your data allowance to use VoLTE. Does anyone know?

It doesn't count against your data plan according to the Verizon FAQ

Voice no, video yes.

It's disappointing that the update is (apparently) only/mainly VoLTE, and not Android 5.0. Since carrier certification is a relatively slow, painful process, I think this is a sign that the Lollipop update is more than a couple months away.
I was initially excited about VoLTE, but I wasn't impressed with it when I used it briefly on my Droid Maxx. First, it wasn't reliable- I had dropped calls, and calls that never even rang my phone. Second, it killed my battery. It was rough- really rough- on it. I think both are related to the relatively weak LTE signal I have at home. To deal with the signal problems I have a Verizon network extender, but it looked like my phone was preferring the weak LTE signal over the strong signal from the network extender.
I wish Verizon would have just sucked it up and supported Wifi calling with Advanced Calling 1.0. I don't understand why they dislike Wifi calling so much. They're going to eventually support it, but the company's statements suggest they aren't happy about it. Who knows how much support there will be for it, though. Verizon apparently plans to release a LTE network extender at some point, which is only useful in certain niche situations if Wifi calling is broadly supported on VZW devices.

Wifi calling is for carriers that need someone else's network to supplement their own shortcomings.
That is why they don't implement it.

So is it just a messaging problem? Verizon doesn't want to support wifi calling because it's an implicit admission that they don't have great coverage everywhere?
Generally, I agree VZW coverage is pretty good. But, it's not great at my house, and its terrible at my workplace. VZW already implicitly acknowledges that they don't have great coverage everywhere by selling network extenders. They're continuing that by coming out with LTE network extenders (someday).
It just seems like its a cheaper, better option to support wifi calling, rather than forcing people (with coverage problems) to shell out $200-300 for a network extender.

I still think every carrier should support this. I'm in IT, and constantly find myself in data centers, or even meeting rooms deep into a building that you couldn't even make an E-911 call from... It really wouldn't be that difficult. When TMob had UMA back in '08 and I had a BB, I used it extensively. It was never because TMobile didn't have enough coverage.. Carriers basically make money when you use their network. Yes, most people have unlimited plans these days, but they build their network around the use it has. So why wouldn't they want you to be using your phone, minutes, texts, etc? On the other hand, why wouldn't they want to offload congestion to networks they don't have to maintain or pay for? There just aren't any down sides to have WiFi calling/text/mms.

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....

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).

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.
