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.

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.

[Q] Is it possible to disable the phone, but keep 3G on?

I want to do some video streaming, but I'm worried that if I get a phone call it could interrupt the stream. So, is it possible to turn of the phone capabilities, but keep 3G data running?

I'm not sure if you can ever really shut off the phone aspect of it, but you might be able to use some blacklisting software to have it send all phone numbers to your voicemail for a certain period.

Go to the settings and enable DDTM. That will send all incoming calls to voicemail during an active 3G session.

Thank you!!!!

[Q] Unable to use wifi while on a call

Title says it all. When I'm talking on the phone I'm unable to use wifi data. Browsing, apps which require data, maps, nothing workings while on a call.
I am running CM6 stable but this issue has been around for a while that I can remember.
Is there a work around? Could I be doing something wrong?
Thanks

Someone correct me if i'm wrong, but as far as i'm aware you can't use data and calls at the same time unless if your using 4g, which of course MC6 doesn't yet support.

You cannot use 3g data while on a call but I cannot see why you cannot use WIFI while on a call. I will test this on Stock Rooted and let you know in a few minutes.

It must be and issue with CM6 as I am able to make a call and surf the web, access the market, etc.. using WIFI at the same time with stock rooted..

Thanks for the confirmation. I've wondered this as well but I haven't noticed any other CM6 user complain about this issue. Maybe there's something in the settings I need to enable?

Its not cm6 or whatever I am having the same issue. No email or surfing while on the phone and simultaneously connected to wifi. Like the first post "title says it all". I am on Stock sprint rom. Just updated to the 3.70, but this problem has been going on noticably for a week prior maybe longer. I was hoping the update would fix it. Any thoughts? or answer?

You can use wifi whiles on a call to browse internet and use apps that require data. I been doing so since I first got a evo months ago. I only used it on one asop rom and that's cm 6.0 rc2 it worked fine when my gf was annoying me with her boring convo lol so i put on the bluetooth headphones and acted like i was paying attention whiles i was one facebook.

When is the last time you tried? I have been trying to use it on a calls all day, with no luck. Only time Wifi connects is when I hang up.
Scenario a: Wifi is turned off; I initiate call; try to turn on Wifi; Wifi will not connect .
Scenario b: Wifi is on; I initiate call; Wifi will not allow surfing until the phone is hung up.
Also when running speed test while on phone will produce very low speeds less than 64k when my speed should be around 12mbps. Again once phone is hung up the speeds return to normal. The speeds resemble a connection that is being throttled.

Are you connected to a Bluetooth headset while in a call?

Just noticed the blue tooth issue. Thanks for the response, but what gives. Surfing used to work while on bluetooth/phone call. For a while that was my only way to listen to music through my BT headset. I had to initiate a call to voicemail and play Iheart.

Heh, it's hit and miss for me.
What i've discovered is......
-If WiFi and the Bluetooth device are connected before initiating the call, it should work fine.
-Sometimes, the Bluetooth device can be connected later, as long as WiFi is connected to a network before call is initiated.
-You can disconnect the Bluetooth device during a call, turn on speaker [or not] to continue the call, and WiFi will connect, but will probably disconnect when you reconnect the Bluetooth device.
-Using method above, you can sustain WiFi connectivity whilst Bluetooth device is connected if you start to browse a website or launch a data required app such as an IM or online radio app, then while it's in the middle of connecting to one of those, reconnect the Bluetooth device.
Lot of trouble? Hell yes. I'm not sure if this is a problem with HTC's software or a hardware problem with having WiFi/Bluetooth on the same chip.

I was about to post this question up on the Hero forum but I found this thread. I have the same problem. Wifi will connect unless on a call but......sometimes if you are already connected before initiating call wifi will stay on FOR A BIT. After a while, wifi will disconnect on its own and if you are lucky it will reconnect later on. Note this is not alway the case. It ussually stays off. I just dont understand why this happens.

Disable HD Voice on Lollipop?

where I am located, if I receive or make a call the HD Voice icon comes on and I am NOT able to use data at the same time. I do not know if the phone was designed this way, but does anybody know if there is a way to disable it so I don't lose LTE when I get a phone call over CDMA?

Our device/network is capable of it yet on the note 4 some older devices have two radios instead of a single

Only something like VoLTE (Voice over LTE) will allow simultaneous voice and data.

Basically what these guys said. With the Sprint Note 4, you cannot make a phone call and use data at the same time regardless if the call is an HD voice call. The only way to make a phone call and use data is only if you are connected to Wi-Fi.

actually, I found a way around this. I enabled google voice for my sprint number, with changes my google voice to my actual sprint cell phone number. Then I use google hang outs to make phone calls. To use data instead of voice, you have to use the hangout dialer. And if you want to receive calls using data, you need to go into settings under the hangout sap, and check the box that says use hangout dialer for incoming calls. As long as the connection is -100db or better under lte and -75db or better under 3g, calls are great.

Technically that doesn't allow you voice + data. It allows you voice over data ^_^. But that also means I won't be able to do things like I could with my note 3 + custom rom. Like playing pandora from my phone to my vehicle while on a call at the same time. At least not without insane buffering issues. But this is what everyone has been using anyway. Did you disable the call monitoring? That drove me nuts until I figured out what was causing it.

You mean call screening? I absolutely did. And the nice thing is simply being able to toggle inside the settings in the Hangouts Dialer whether or not to have calls go there. That way if its a sketchy data area, I just take calls in the standard dialer so the call quality doesnt suck. It works good so far. Especially where my kids go to school while my wife is on maternity at Home. Data is good standard LTE or band 41, -80db or so, so I can talk and use the net or stream at the same time.
