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.

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.

Evo - Won't stay in 3G coverage

I'm having trouble with my EVO staying in 3G coverage. My phone is fully rooted and running Froyo (The problems were the same with the Eclair build however), have the 2.05+ radio installed (however the problems were the same with the 1.39 radio as well) and I'm living in Michigan.
At any given time my phone will slip into 1X coverage and will seem to lock in there. When I first received the phone I felt like the phone quality was subpar compared to the Hero I had prior. I'm not sure if its been a firmware issue or network issue or simply a phone issue (starting to think the later), but hoping its a simple fix with something else.
About a week ago I was on a trip across Michigan which should have had 3g coverage the entire way (I was a passenger and trying to use wireless tethering to do some work along the trip). I would constantly go into 1X and would have to restart my phone to get back in 3G. Even at home I'll go into 1X and will have to reboot my phone to get it back to 3G.
I've tried Real Signal as well during these times and it also shows no 3G signal.
Anyways, anyone else experience this? Is it likely a bad radio or something else. I hate to have to return the phone and go through that process plus root again but I might have to at this point.
Thanks for any help that can be provided!!

Hmmm, whereabouts in MI? I am all over the south east and have never seen my phone drop out of 3G yet.
Have you tried wiping everything and trying stock rom w/OTA 1.47 just to make sure it isn't the ROM?

I am having the exact same problem. Using 2.0xxx radio and Fresh 0.5.3. I recently exchanged my phone and got a new one. The first phone did not do this
Try this:
When it shows you no 3G coverage, instead of restarting, go to-- SETTINGS> WIRELESS & NETWORKS> scroll down and look at "Mobile Network". When i get the 3g problem it says "Connection Failed". I think uncheck that box and re-check it and it connects back to 3g again (for a time, but then I have to do it again).
My MOBILE NETWORK settings are: Data Roaming = OFF, Always-on mobile data = ON, and CDM Roaming mode is set to: SPRINT only. Call guard = ON but i dunno what that means.
I dunno wtf is going on with this. Im in Houston and this issue is really pissing me off because i actually got a Novatek screen this time and don't want to risk taking the phone back and getting the Epson...
Anyone else experiencing this retarded issue?

Elegant: I'm in SE Michigan as well. I've tried several roms and have had issues with them all. I'm currently using a Froyo rom with similar issues as I've had with stock and other eclair roms.
As for checking/unchecking the box as you stated in Froyo I don't have that option available... I'm sure there's another way to get to it but I can't through settings. I think there was a #* code to get to where you are talking about but I'd have to look again.
It is a very annoying issue and like yourself I don't want to have to return my phone if there's a simple fix.
On a side note: How do I find out what panel I have? I've been considering the kernel that would get rid of the 30 fps cap but haven't yet pulled the trigger in part because I don't know which panel I have - and because I need to learn a little more about it before I go ahead with it.

http://forum.xda-developers.com/showthread.php?t=719763
Post 3 tells how to determine screen

Thanks for your help - got the kernel and now get around 40 FPS. Now if I can just figure out why the phone goes in and out of 3g on occasion. Its really not as big a deal when I'm at home but when I travel it is a pain.

well i returned my phone and got one with an Epson screen. im using Fresh 1.0.1 and it is even worse. i cant even use 3g data for more than 5 seconds before it disconnects. i've read some stuff about APN but dont know how to refresh/update them. i've updated PRL and Profile and nothing helps. how am i having this problem with 2 phones running 2 different ROMs? last rom was fresh 0.5.3 and now it is fresh 1.0.1...
anyone help with this APN issue? (i dont even know what APN stands for)

i actually am using the kernel for 55 FPS for Epson screens. would that be a factor either?

I'm and having the same issue with 3g.
Every thing worked fine with the first stock root of 1.32.651.1, PRI 1.40_003, PRL 60666.
With the second root of 1.47.651.1, PRI 1.34.651.1 now my 3g is unstable.
I don't know what FPS has to do with any of this, but I put radio radio-1.39.00.04.26 and it seems to improve a tiny bit, but I don't know how to update back to PRI 1.40_003.

Not happy
Also having problems in SE Michigan. Just started today after installation of Fresh 1.0.1 and the new radios. I also have a co-worker with and unrooted EVO and the latest OTA/Radio with the same problem.

I have a rooted EVO (DC 3.2.3). My wife has a stock EVO (fully updated).
Last night our phones started bouncing between roaming/sprint 3G, while we were sitting at home.
We started getting this error if we turned off Data Roam:
"Data Call Failure
Error Code 67: Registration failure. Your PCS Vision username and/or password may be incorrect. Please try again."
The error pops every time it tries to connect to Sprint's mobile network and fails.
We also live in Michigan. Perhaps they are doing provisioning?
Rebooting + update Profile/PRL seems to help, sometimes, but not permanently.

I am having the same issue with my 3g coverage.
When I go into my settings and turn mobile network on, it connects but then immediately says connection failed.
Does anyone have any suggestions as this is getting really annoying and frustrating.

Went to a Sprint store last night; apparently Michigan was having some significant network issues (the store reps said their phones kept getting disconnected as well), and that it was expected to be resolved by sometime today. After a reboot last night, I haven't had any more issues myself.

Why data connection lost and why reboot fixed it?

Hi,
Using GNex, stock JB 4.11, Wind Mobile Canada, $40 plan, unlimited data & Canada wide.
Please excuse in advance for the novice questions. I am not yet familiar with Wind Mobile. The customer support is too long and submitting a question to their website required around 5 days to get an answer which is generally irrelevant in my short experience. Hope some expert users here can share some of your knowledge.
Last week, suddenly during a phone conversation, the phone became totally disconnected voice & data. The next morning, the situation didn't improve, so I rebooted the phone (power off / on). Then the phone could connect to voice, but no data (gray icon instead of blue). I stayed with no data for 3 days. During that time, I tried a few reboots, changing various network settings (APN, Network Operators, Data roaming, etc.). None of that worked, then I made another reboot and suddenly everything is back to normal (no roaming and data OK).
Q1. Signal strength variation: what is the cause that makes a signal vary? For the same location, sometimes signal changes from 3 bars to 1 within a few minutes.
Q2. What caused a network to black out temporarily? That's what I got last week during the entire night. The reception icon is a black outline triangle (no voice, no data). I purposely disabled roaming, I admit a network could have some issues, but I have hard time to admit that a disruption could last 12 hours. May be the issue is my phone? It was not rebooted since 7 days.
Q3. How often should I reboot the phone? By reboot, I mean power off/on. I hope this is the correct term. Is it possible that a frequent reboot help the phone to be more responsive? I tend to think so because all the network issues I got were magically fixed by reboot.
Q4. Why would a reboot fix a data connection issue? In my case, a few reboots on day 1 didn't fix. Many network settings changes didn't reconnect data. Then finally another reboot on day 3 fixed data connection.
Thanks in advance for any help.

Welcome to the Nexus and its crap radio. Try turning off 4G, once I did that I never lost signal again. With 4G on I get disconnected from the network randomly throughout the day

How to turn off 4G? Wind Mobile operates on AWS network 1700/2100 MHz (UMTS band 4), and HSPA+ for data. I believe it is not 4G. On the phone Network Settings, there is only an option "Use only 2G Network" which is not a good option for me. If I enabled "Use only 2G Network" the phone shuts off data and changes to roaming mode.

Any number of influences. A microwave, air ionization, temperature, humidity, output from the tower not consistant, and plus just the variations of the phone. Going by bars is a bad way to gauge anyways, it could have only dropped signal for a split second but it doesnt update the bars frequently so it would appear to be low signal longer than it could have actually been. Your phone works by line of sight, picture a tight wire from your phone to the tower, anything that crosses in that line reduces signal.
Q2. What caused a network to black out temporarily? That's what I got last week during the entire night. The reception icon is a black outline triangle (no voice, no data).

That actually is hard to answer, you would need to contact your provider to see if they have a log of an outage at that time before going into whether it was the phone or not.
Q3. How often should I reboot the phone? By reboot, I mean power off/on. I hope this is the correct term. Is it possible that a frequent reboot help the phone to be more responsive? I tend to think so because all the network issues I got were magically fixed by reboot.
Never unless things act funny. A reboot is usually healthy for operating systems (i know many do not). I personally don't intentionally reboot mine, it usually happens because I'm screwing with clock speeds
Q4. Why would a reboot fix a data connection issue? In my case, a few reboots on day 1 didn't fix. Many network settings changes didn't reconnect data. Then finally another reboot on day 3 fixed data connection.
Like any software there are chance of a 'glitch' where the modem and the driver have issues communicating. Toggling airplane mode off and then back on re-initializes this and in most cases fixes the communication problem. Rebooting will have the same effect. I would only worry if you are needing to do this often.

Hope this helps a little.
I would also contact your provider. They may have an issue with the tower you are connecting to.

Perfectly understood, appreciated very much your detailed answers. Can you please clarify below?

Makes sense. Indeed, when I said "For the same location, sometimes signal changes from 3 bars to 1 within a few minutes". Actually, I mean a room and I was walking/moving so may be the orientation of the phone explained why the reception was inconstant.
Regarding your answer above output from the tower not consistant. Is it possible that the tower reduces its signal strength when the number of users increases? Similar to users sharing a finite band width?

Yes, even orientation of the phone can have an affect, depends how the antenna is set up inside the phone, i havent seen it so i have no answer for that.
ya, as you move around you could have been what blocked the direct sight of the tower, signal passes through nonmetal objects but each time it does, it loses strength depending what it passes through

@OP I also have the same problem, I am also with Wind and had to do force reboot to make it reboot.

Sprint G2 LTE/3G/data in general problem

About a week ago I was using my G2 and everything was working perfectly. I then went into updates and did a PRL and Profile update and BOOM my LTE stopped working and I was forced to 3G. Now for the past 4 days or so my 3G barely works and most of the time I get no data at all. I'm even starting to get zero bars and a red x. I've tried nearly everything I can think of to remedy this issue but nothing I've done has fixed it.
I've gone into the hidden menu and enabled LTE only and the LTE comes on and works great! But...You can't just be on LTE only because then CDMA doesn't work and you can't receive calls or texts. I've also turn the phone from voice centric to data centric but then I couldnt receive calls, I could only MAKE calls.
I've done all the obvious stuff like turn my phone from global to cdma/lte and vice versa. When I reset my phone LTE will come on for 2 seconds tops then stop and push me to 3G...then after a while 3G will stop working.
I'm completely stock, not rooted.
I've talked to a guy at sprint and he's told me that they know the G2 has issues with CDMA/LTE switching
Any help would be greatly appreciated.

I have read some people say take it in and out of airplane mode to get lte back but i would think a reboot would correct the problem as well. Maybe you have a sprint tower down in your area.

I thought this was only happening to me. LoL ... Eventually I got so frustrated that I moved to TMobile.v Even when I got good connection it was still horrible if that make sense. My wife doesn't have that problem but I'm moving her to TMobile to.
Did you try to do the permanently unlock at one point? That's when it started happening to me.

Actually it's a Spark issue. The only remedy is to wait for Sprint to put out an update or disable spark. You can disable it by dialing ##data#, go into LTE - edit (you'll need your MSL. There's a dialer code to get it just look here on the forums) then disable bands 26 and 41 and set their priority to 0. Afterwards your LTE will be back to normal.
Edit - ##443336772# Shows MSL code near the bottom of the screen

It almost seems to be an LTE handoff issue - they had similar issues with other devices during the buildout here in Chicago (my poor N2 was nearly 3G for almost 6 months due to the issue. I occasionally have issues but ##SCRTN# has resolved them.

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.

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!
