Can't receive calls when using Data network

I'm using T-Mobile HTC Touch Pro 2 on AT&T network and cant receive calls when I'm on data network (read browsing, facebook app, slacker radio app).
I'm on AT&T EDGE. Is there anything that can be done to avoid this? Thanks.

The problem is that when you're using your T-mobile phone on the AT&T network, your data connection is through EDGE, not 3G...and one of the drawbacks to EDGE is that you can't have an active data connection at the same time as an active phone call.
It's a hardware restriction, caused by the different 3G bands AT&T and T-mobile use. Your only real solution would be to get an AT&T-branded phone so you can use their 3G bands, or start using t-mobile's network with your TP2 so you can use their 3G.

Agreed that you can't do both at the same time, but it sounds like the phone should still automatically suspend the data session to take the phone call. Sounds like an application is forcing the data connection to stay active, what programs do you have installed?

I think it would be nice if it worked that way....but that's not how it's been for me. Maybe there's a registry setting that makes it one way or the other, but on the custom roms I've used it doesn't work the "nice" way. Calls go to voice mail if I'm actively accessing/transferring data (on an EDGE connection).
Are you saying that your TP2 actually does suspend the data session -- from personal experience? Or just that it should be that way?

I can't say for sure on my TP2 as I've generally got 3G coverage everywhere I go. When I was using my 8525 I specifically remember being impressed the first time I was in the middle of a download and it recovered after taking a phone call, was definitely a custom ROM too. Probably was WinMo 6.0 at that time though.

When you are using data and recieve a call it should stop data and allow the call to go thru when you are using EDGE. Since you are using a none AT&T device they probably wont fix the issue unless you reproduce the issue with an AT&T device. Also i tested this on my TMO TP2 by loading a website and making a call to my TP2 at the same time and it stopped my data as the call came thru then when i ignored the call it continued to load the website.

It may depend on other factors then -- like maybe what rom you're running. After I posted above I tested this again -- to confirm what I posted, by starting the download of a very large file. I then called my phone from a landline and sure-enough the call went to VM after a few rings. So, maybe just a characteristic of my ROM, but it's definitely true for me on T-Mo USA (on EDGE). When I stopped the download my phone received calls just fine, so it's not a general receiving-calls issue.
Tomorrow when I'm at work -- and have a full-strength 3G connection -- I'll try it again to confirm that it does receive during 3G data. I've done that test before -- I've received calls with my laptop tethered to the TP2 on 3G and kept the data connection and received the call, but I haven't tried with the rom I'm currently running.

I experienced the same thing with my EDGE-only Wizard (8125) on AT&T...incoming calls would be routed straight to voicemail if I had an active data connection going. And, whenever I would try to make an outgoing call, I would get an error message telling me that I couldn't make the call until I closed the data connection.
We all agree that EDGE can't multi-task like that, so to speak...but I think the issue of prioritizing or not prioritizing voice over data is handled at the device level, and/or by carrier control, rather than as a function of what the network can/can't do. My guess at this point is that there might be a reg setting that controls giving calls default priority at all times, but I have no idea what/where it is

Yeah, that's what I was thinking....well, guessing really -- I don't know. But I know what my experiment showed. A registry setting could explain why it would work for some and not others. Or could a different radio-rom possibly make a difference?
I have no idea.

Now that you mention it, my money is on the radio (don't know why I didn't think of that).
blueguy, what radio are you using? And for that matter, what ROM? ATT, Tmo, or...? I'll test it on mine just like MCbrian did, since I have a different radio (.14), once I recall how to force my toy into EDGE-only mode. so, tomorrow morning
EDIT: sik96teg, same question to you...what radio/ROM are you using?

right now im on 4.49.25.57(i believe this is the stock tmo 6.5) radio and i have tried a few other radios over the last few monthes(never really tested them but dont recall this issue). i use to be on an energy rom and now im on leo cell evo rom. Also when i did have this issue a long time ago i called tmobile and they stated at the time it was a known issue and it was suppose to be resolved in a few days and a few days later it started to work. I also made about 10 calls and only one of them didnt come thru to the phone. My home phone rang for about 30 secs then went to vm but no indicator on the device but that only occured 1 out of 10 tries.

Just confirming what I thought: On a 3G data connection, data-transfer continues and the voice call is received simultaneously, as it should.

Thanks for your inputs and my answers
I'm using Tmobile ROM which upgraded me from WinMo 6.1 to WinMo 6.5. I'm not sure what was the radio on it. But I flashed it with Hard-SPL and then with 4.49.25.88 Radio.
Even then the issue still persists
I read somewhere it happens due to NOM1 and NOM2 kind of EDGE network. NOM1 has capabilities to suspend data connection and give preference to phone call, NOM2 doesnt support this behavior. It seems AT&T is using NOM2 in my area. I'm not sure though if this is causing the issue that I'm experiencing.
I called AT&T Technical Support and they said they see my phone as Unkown device and can' support it.
Please this is really annoying, any help is appreciated.

Same here, I am currently with the new official (ok better leaked) ROM and the Radio that was provided (the latest).
The point is that when I am on 3G i can receive both data and calls which is obvious. Now after reading this thread I noticed that when I am on standard GSM and someone calls me, they get notified that my phone is switched off.
What is weird is the fact that there should have been an option to state Call over Data or the opposite for that matter. I think my old Nokia N95 had a similar option.
So, yeah, is that a bug or a feature?

i'm just guessing...but, I believe the simultaneous data/call is a function of 3G .....EDGE is the bare-bones basic thing....
at least that's how they make it sound in the commercials
....i should have read the replies in the thread...

When I tested this (on EDGE) by calling my TP2 from landline it went to voicemail. Another time I was on EDGE and someone tried to call me and they had your experience: "Out of area/unreachable". And this was within 24 hours, on the same rom without changing any setting (at least, not on purpose).
I've never seen an option to set data/voice priority.

I flashed Energy ROM with .88 radio, it did improve download speed. But still don't receive calls while using data.
Is there any other ROM which allows this?

The Rhodium isn't capable of simultaneous data and voice.
You should have a GPRS Class A phone, but that should have 2 antennas. (See link)
So only one of them is active, data OR voice.
But normally it should pause the data connections and give priority to the voice connection.

I believe it IS capable, if you are on 3G data. Not if you are EDGE / GPRS.

Yes -- it absolutely is, as stevedebi states, on 3G. So the limitation on EDGE isn't the phone, really, it's the nature of EDGE/GPRS.

A few questions about the GNex - Network, Mail etc.,

Hi Guys,
So, I've been using the GNex for about a month. I moved to this phone from a Moto Atrix and here is what I have noticed and have looked around but didn't see any good answers to these questions I am having. Hopefully I get some answers here.
Device info:
GNex GSM version on ATT.
Running JB 4.1.1 Stock with Trinity Kernel (rooted and bootloader unlocked).
Issue #1: I get really bad reception at work. But, when I leave the building, my phone doesn't automaticaly connect back to the network. Sometimes, if I don't check my phone, it's been like that all night long until the next day when I have tried to make a call and it said "No Network Available" and I have to either reboot or toggle airplane mode to get back on the network. Am I missing something? In my past experience with other devices, they try to automatically connect back to the network when they loose connectivity. Also, if I get in an elevator during a call and the call gets dropped due to network unavailability, it doesn't connect back to the network and I have to toggle airplane mode. Has anyone else had this issue?
Issue#2: This is with the stock mail app. Specifically the search in this mail app. No matter what, it always returns zero results. Has anyone had this issue with the Mail App? If I use the Gmail app, it works fine. That's what I am using now, but am curious as to what I may be missing that make it not return any search results in the stock mail app.
Q3: Speed Dial: How do you set speed dial on the dialer? Is it even supported?
thanks in advance,
vG

it could be to do with your radio, what version is it? baseband version in about phone. im no expert but when i flashed a jellybean rom i had to update my radio afterwards cause my signal was dropping alot. i also had the same problem later on but that was down to my network operator. before i realised it was them i googled my problem and a few forums suggested that my sim card was goosed. so maybe check those three possibilities? i cant help with the other two issues unfortunately but good luck sorting it out!

Not connected to Mobile Network after being on Wifi?

This has been a frustrating issue I've been having pretty much since starting up my T-mobile service about a month ago.
To start off, my G3 is unrooted and on the latest stock software version, 20e.
I use Wifi calling often because I get 0-1 bars of reception at work. All seems to work well until I go outside and try to make a phonecall over the voice network. I'll have plenty of signal bars, be connected to 4G even, yet when I try to use the phone dialer to make a call it will say "Not connected to Mobile Network." or something along those lines.
I haven't done extensive testing, but I believe the other day I toggled the "Mobile Data" off then back on and was able to make calls.
Has anyone else had this trouble? Is it something possibly to do with Wifi and/or Wifi calling?
I believe I could make a phonecall using Hangouts when I was off of wifi, which tells me that the data part is working, but not the voice network.
I contacted T-mobile support, but they just had me do the "typical" things, like shut down the phone, remove the battery/SIM, start everything back up. And sure enough, it worked after that, but I'd rather not have to restart my phone or toggle stuff to get it to work as it should without any hassle.
Thanks!

My wife has the same problem after the 20E update. Her mobile is stock as well. It did not happen on 20B.

Off the top of my head no. I'll dig around a bit and see what if anything I come up with.,

From the digging I did I can't seem to find any help. The only thing I can think of is to factory reset it thing and see if it helps. I am going to do do it on my wifes phone tonight.

Yeah, that's what I was thinking too... I'm not really in the mood to deal with restoring all of my apps and whatnot, so I'll hold off on the factory reset for now.
If you remember, could you let me know the results? If I know for fair certainty that a wipe will fix the issue, I might do it.
Thanks!

It's a network problem and it is worst on Samsung phones. I recently went and got a new sim card and it seems to have fixed it. I read it is because if you live in a area where there is poor coverage it causes your sim to where out fast.

This started happening before my first month of T-mobile service was even up with a brand new SIM. I'm not saying that it's definitely not a SIM issue, just would seem unlikely that it's worn out that fast.

Mobile out of Network-Tmobile - Android
I;m having the same issue, turned phone off and on, checked Network connections everything looks fine, but now able to receive and send texts or make calls.

No VOLTE/Advanced calling.

I picked up this phone a few days ago and I just noticed that VOLTE wasn't working like it should. The settings menu shows that I have the option on, but everytime I make a call or receive a call it instantly switches from 4g to 1x, and therefore I don't have simultaneous voice and data. Anyone have this issue too?
I checked my Verizon account to see if that feature is enabled for my line. Advanced calling shows that VOLTE is on for calls and video chat. Turning it on and off doesn't change anything, turning wifi calling on and off doesn't affect it. I've tried rebooting, and no luck. Seems like a software issue?

I noticed this on a call today as well. Subscribing...

Perhaps the person on the other end needs it as well? I've found calls between my girlfriend and I would switch from HD to non-HD and it seemed like it was due to service on her end. Just a thought. Its actually only happened a couple of times to me.

No luck with that one either. I've tried calling other lines on my plans and I got the same results. My S5 did a pretty good job maintaining HD Voice every time I made a call to those lines where LTE coverage was available.
I called CS and they didn't say it was a common problem, but they put in a report pretty immediately for me and should have someone contacting me the next 24-48 hours.

Just a quick update. I didn't do anything, I used my phone as is and it just started switching to HD voice and maintaining LTE while calling. So either they did something on their side, or the phone is just a little buggy.

I have never had that VoLTE icon pop up on my phone but if I look in my recent calls list I do see a Wifi icon on some of the calls.. I assume this is VoLTE??

That's WiFi calling.

I have used WiFi calling and it seems to work alright. Is this the same as VoLTE? If it is not how do you enable VoLTE?
I just found it in settings, it is enabled however I have never seen any kind of an icon that it is working. How do I know if it is or isnt?

Where is the setting for VoLTE in Settings? I am not seeing it anywhere.
EDIT: A google search showed me it should be in call settings, but it is not there. Any help much appreciated.

Cant use mobile internet whıle on call

hi there,
i am new with OnePlus, and am i really so happy from that decision.
just i need one strange question. While on phone call i cant use internet connection on my both service provider ( different gsm companies btw ). even my old M7 was able to done that. have i done something wrong on settings? or this is like that?
thnx
regards

I can't use internet while on call me neither

No issues here. But I'm using a single sim for both data and call.

Iam on OOS 8.1 beta 4 using 2 sims, same can't use 4g when on call but only sometimes I have noticed my 4g drops down to 3g while on call, there should be a solution to this, I am gonna try some 4g booster apps from play store lets see if they help, cheers everyone.

Don't think this is an issue. I don't recall I could do this ever on any phone. But if you are connected on wifi there is no trouble at all. Guessing you can't do both ?

there's an option in "developers options" "mobile data always active" , if u read the little detail underneath it it says mobile data will be on even if the WiFi is connected I presume this way both will be on, but I still don't know if mobile data disconnects at the time of making a call, but I will experiment and see what happens, cheers.

I had the same issue on my OnePlus3 a while ago. I haven't encountered it on the 5T though. I'll try to look for a solution when I get home. In school atm.

I'm using turkey Vodafone and when I'm on call i can use internet but it drops to 3g from 4g, unless you use volte its normal when it drops to 3g.

Yep definitely an issue. I'm Virgin Media and EE
Don't remember it being the case on the OP3 but could be wrong

On op3 I remember having the same issue. And note 3 and note 1 too. That's why I don't think it's an issue per say. Maybe a wrong implementation or something. Can maybe be fixed by a piece of code (magisk or xposed)?
