Can't receive calls when using Data network - Touch Pro2, Tilt 2 Windows Mobile General

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.

new HTC user here having a weird problem

hey guys
ok so i have the TP2 running WM 6.5 professional
ROM 1.86.401.0 (67102) WWE
ROM date 25/9/2009
radio 4.49.25.17
protocol ver. 61.44tc.25.32U
my service provider is Etisalat in the UAE
the problem that im having is that when i set the BAND to AUTO, it picked up the the 3G network...but problem is that it keep shuffling between 3G and EDGE. because of that it wont recieve calls. one fix i was told was to manually select GSM BAND. the call problem was solved because of that.
but since i have done this, i been having another porblem. after using internet to say update the weather tab, i cant make or recieve call, or send sms or anything. everytime i use internet on the TP2, i have to switch to AIRPLANE MODE and then back to PHONE its driving me nuts
anyone facing the same problem? or has a fix to this?
Switching between 3G and Edge is normal, because not everywhere you have good service.
But just to make sure:
When you set band to AUTO and you are switching between 3G and Edge, can you call someone?
I had problems with my HTC Kaiser in the UAE. Etisalat and Du told me they only can provide mobile internet to BlackBerries and IPhones...
yeah, when it is switching between 3G and Edge, i cant make calls and i cant recieve calls either. they say my cell if off while its actually on

Go into the Bands page (where you manually select the bands). Press "WCDMA" to enable 3G only. That will keep you in 3G, but if you go into a non-3G area, you won't get any signal at all.
EDGE can only handle one thing at a time. If you don't have an active data connection, you can use the phone (call, SMS). If data connection is active, you can't use the phone functions. So, if you're on a webpage and someone calls you, their call won't go through.
3G allows you to use phone functions and data at the same time. So if you're on a web page and someone calls you, you can answer it.
ok that was surprisingly simple.. thanks
Edge can only handle one thing at a time? I routinely get and make calls and browse at the same time (or get emails via active outlook push connections, etc). And this is both when I'm in Edge areas (eg when I go to my cabin in Montana (heck - ANYWHERE west of Milwaukee) or when I have 3G (around here).
This does, however, appear to be a feature strictly of AT&T. But I don't believe the inability to do simultaneous data and call is a hardware or even Edge technology limitation - I believe its a network specific limitation.
Having said that, my money would be on an incorrect radio or DLL hanging around in the phone...
(Standard disclaimer: I know nothing about non-US carriers or their oddities. I reserve the right to be wrong- a right I exercise somewhat frequently )
well i upgraded to WM6.5 so the radio is the one that came with the upgrade.nothing else has been changed.
have a feeling the problem is with the phone as my pervious phone, sony ericsson's P990i had absolutely no porblems switching from data to call and back to data without having to do anything.
one thing i noted is that once i start an internet session, it keeps running unless i turn the switch to airplane mode to force a connection break.

Simultaneous call and data

Just started using my Desire last night! Feeling good.
However...
Was just on a call, tried to use the Android Marketplace. Couldn't.
Got curious, and tried to use Google Maps mid call. Couldn't.
Tried to use the internet during the call. Couldn't.
Now, I'm on T-Mobile (UK) and have just come from a Nokia E71. With my E71 I could make a call and use Google Maps.
Am I missing something or is this bit of multitasking somehow not possible???
Please tell me I'm missing something!

A lot of carriers don't currently support simultaneous data and voice. For example, I have Sprint and it has no support for this - very annoying.
AT&T is the only one I'm personally aware that supports both talking and using data at the same time.
If it doesn't work for you, you're out of luck with your carrier.

Sprint is a CDMA network, and most CDMA networks don't currently support simultaneous voice and data.
Most GSM networks do support this when you have a 3G connection. The voice call is routed over 2G and the data over 3G. If your data connection drops down to GPRS or EDGE, you will lose data connectivity because most networks do not support simultaneous voice and data over 2G, though I'm told that they can be set up to do so, so I guess it's more down to bandwidth.
Regards,
Dave
I know that Sprint's CDMA has an issue with simultaneous data and voice. Which suck. And I know they are making good attempts to sort this out for the EVO, which is good.
But again, I've been doing this fine on my E71. The only thing I can think of, in relation to Dave's comments, is that for some reason, because the Desire can suck up more data, T-mobile have restricted it. Which would suprise me because, as Dave said, simultaneous voice and data is a feature of most GSM networks and has been for a while.
I have just tested that and it's true - the phone doesn't have simultaneous data and voice connection
Now normally I don't need that because if I talk, I talk and not browse the web, but even my freaking G1 could do both things at the same time. What the heck? It must be something HTC did.
One more reason to eagerly wait for root...
I don't see how this is a big deal. Why would you need to make a call AND browse the market place or look at maps etc? Surely it's something that can be done after the call even if it is receiving directions or whatever.

It's a big deal because:
1. HTC (or T-Mobile) has obviously done something to disable it because Android with GSM should have such functionality;
2. Older Android phones and even some "dumbphones" have that functionality
3. No point in browsing market while talking, but what about looking up maps while talking? - That was even one of G1's selling points.
I have often been on a call and used the internet or searched Maps. So it's something that I am quite used to doing.
Though I thought I'd get an answer straight from the horses mouth and have emailed HTC support just now. I'm hoping they give me good news...
False alarm. This only happens on GPRS, which is normal. Simultaneous data and voice connection can only happen on 3G as explained in Android Forums.
and of course correctly explained by Dave in post #3 here.

Kind of tired of explaining this one but here are the 2 use cases:
- you're talking with someone on the phone and they ask you for directions, look something up on the internet, see if you received their email, etc, etc
- and even more importantly, when my rooted phone acts as a WiFi access point with android-wifi-tether and someone calls me, my freaking Inet disappears until I'm off the phone. This is the more annoying of the 2 use cases.
Well, this was their reply:
"If you start the call being connected through 2G, then yes the internet will then work. But as soon as the signal goes over to 3G then the internet connection and usuage will be turned off.
When it comes to wifi, if you are in a call and you are connected to wifi, then you should be able to surf.
Hope this answers your questions.
Thank you for contacting HTC. "
I did get concerned for a second. I've just tried the wifi and call which worked. And I just tried a call again, with wifi turned off and it worked, even though it didn't work before.
I just hope it routes voice and data in a way that doesn't trip me up in the future. I.e. voice over 2G if I'm trying to access data.
So yes, false alarm.
And funnily enough I just now got a call from Carphonewarehouse asking me if I'm having a problem sending texts as some Desires do indeed have a software fault where they have no Service Centre number for messages. For once, I've skipped the faulty units!
Cheers guys. Sorry scare anyone.
lol.
Whoever it was at HTC got their 2G and 3G mixed up.
what they meant to say was if it goes down to 2G then it'll stop.
You'll be ok in general, as long as you have 3G signal wherever you are. If you've only got 2G, you'll have to hang up, find out and then call back!
the SMSC shouldn't be a problem though, just program it in manually. Not worth sending a phone back for unless it fails then as well.
Even if I'm on 3G/HSPA, when I call someone, as soon as the call is connected, my data connection disappears (only shows bars, no G, 3G, or H) and I can't browse the web or use maps while in-call :-/
ok, well that's not right. The bars should only disappear if you turn the mobile data off. it should not get turned off by a call. Even if i try it when in G, the bars stay showing, just no data comes till i hang up the call.
If the bars are disappearing, something else is going on.
It could be a local network issue. maybe it's an old transmitter that missed an update or something...?could possibly be a full tower.
I know that a few years ago, the towers would kick off data connections to allow more airtime for voice calls which have priority, but i don't know if that's still relevant on 3G.
This was a hot discussion back when the Hero came out as well.
In the end I think it comes down to the network of your carrier. Some people report they can internet and call at the same time. Others say when they are internetting on their phone, a call is directly forwarded to their voicemail etc.
I'm afraid it's a combination between how your carrier configures their network and on what connection you are on (3g, 2g etc).
Yeah it's false alarm no #2 -- must be a spotty 3G at my house. I went to the city centre and tried it there -- worked like a charm.
Though it's a bit weird as 3G speed is not bad at all at my house, but when I call, data connection goes off :-/
Maybe at the city center you got more cells in range than in your house. Means your carrier got more available bandwith
I think reception gets spotty. Sometimes voice and data works, sometimes it doesn't. At home in my bedroom I can get H connection, 20 meters away I can't.
I think the important thing is that the phone is capable. The rest is just pinning down exactly the situation that we want to avoid.

Voicecalls not coming through whenever data is on

Guys
Noticed something funny with my Galaxy Nexus. Calls don't seem to be coming through whenever it is transmitting or receiving data on the 3G. I can still make calls no problem.
My previous phone (the N97) would disengage packet connection (a warning comes up) before the call comes through.
I'm still analysis the data but I am hoping that one of you has experience this before and can offer some insight.
I've done the following test:
1. Wifi and 3G on. Some calls come through, some goes to voicemail.
2. Wifi and 3G on - streaming a video from my NAS box - Some calls come through, some goes to voicemail.
3.Disengaged Wifi and 3G on - Some calls come through, some goes to voicemail.
4.Disengaged Wifi and 3G off (2G only) - Calls comes through fine (when I send text I get the volume bug).
5.Disengaged Wifi and Data on but only on 2G - Calls comes through fine.
In all above instances when the 3G/data is on, I make sure I am transmitting (I synch my hotmail account).
So is this normal (this is my first android phone)? Am I the only one or are there others?
Any feedback would be appreciated.
Thanks

Which network?
It's certainly not normal behaviour in Gingerbread and earlier at least (still waiting for my GN to be delivered). Even on 3G calls should be able to come through and then if needed decide to switch down to 2G if it decides it's needed.
Have you confirmed that you can actually make and receive call on 3G currently? Might be something wrong with your plan or your SIM.

I'm still testing but it does appear that whenever it's transmitting on 3G (3G or H in the icon) incoming calls go to voicemail.
I just did another test, in the previous tests I was just calling my voicemail service (901) but I decided to call my house phone and here's the strangest thing.
- With the wifi on and 3G I couldn't make any phone calls (apart from the voicemail), the calls just end. I turned off the wifi, tried making a call it works. Then turned on the wifi on again and I can make calls again. How bizarre.
I'm hoping it's a network issue but I won't know until say about a weeks time (if its a network issue it should have been fix within that period). But my first adventure with Android isn't going very well.
Rang O2 and it sounds like an issue with the network . According to them 3G was affect all over the country recently and still have issues in the London area.
I also put my sim back into my N97 and after numerous attempts was able to replicate the fault So happy.
But the customer support suggested that I should still go and get a replacement sim from the shops tomorrow since mine is quite old. From 2009 but still 3G enabled.
So fingers crossed that its def a network issue and not a fluke that it affected my N97.
How will a new SIM be able to work better? I thought, as long as it has 3G, it's all good?
My SIM is from 2008, I guess, so quite "old", as well...

Does SIM age really matter? I've been using the same SIM card since 2005.
I don't know if the age of the SIM matters, but what I do know is after I replaced my old SIM (AT&T) my data got faster (a few phones ago).
It never hurts to use a new SIM. The manufacturers change every few years (gemalto, etc) and I'd bet that newer is better...

[Q] Voice calls and data at the same time?

Hello,
I just got this phone yesterday. Upgrading from HTC Evo 4g LTE.
Today I was on a conference call and tried to access the web and could not. I noticed I did not have the LTE or any indication of mobile data networking ( associated icons). Does this phone handle voice and data at the same time ( not on wifi ).
If not I will have to return this in disbelief.
Thanks
Mike
Please close this thread. After searching i found this thread:
http://forum.xda-developers.com/note-4-sprint/help/simultaneous-voice-data-t2893885
Doesn't seem like you can use data and voice together. A work around looks like hangouts dialer. I just downloaded it. Error " phone calling is not supported for this account with this version of hangouts ". Guess i'll have to use the search field to see what/if anything can be done.
Even though I got that error message I was able to make a call. Worked on Wifi and LTE network....this might work out.....

This is a Sprint Spark limitation. All Sprint Spark phones are limited to 1 radio at a time, so you can't have 1 channel running voice and another running data. When you are making a voice call your phone drops down to 1xRTT. The up side is better battery life and the ability to use 800mhz, 1900mhz and 2500mhz LTE (one at a time), the down side is no Simultaneous Voice and Data (unless you are on WiFi).
In the long term everyone will move to Voice over LTE, which will allow data and voice simultaneously again. There is no time frame for this yet with Sprint and the Note4 was listed in the FCC specs as not supporting VOLTE.
Do all new sprint phones have spark? Any time frame for volte?
I had heard whether it's true or not Intel late 15 early 16 for the start of roll out of volte.

Thanks everyone. Guess i will have to see if i can do without data while using voice.
Get a note3 pretty close to the same phone ya I know there are some major difference but if u really need date and voice that will be way more important than any lil difference between phones

Thanks @sliverr7x, I would do that, but i want the newest available phones.

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.
