Phone calls drop data on 3G?

All, I am sure there is a thread on this somewhere, I just can't find it... please help.
I've got an AT&T Tilt with stock ROM, no bloatware. The problem is that when a phone call comes in (or I dial out), it seems to drop or interrupt the data connection even on 3G. Very annoying.
On my 8525 with WM6 ROM, this never happened. I could be connected to the internet (typically connecting my laptop via Internet Sharing on the 8525), and be talking on the phone at the same time -- the data connection was never interrupted. Of course if I was on an EDGE or GPRS network, it would -- but that's to be expected since GPRS/EDGE use the same radio as GSM. On the 8925, as I stated above, a phone call interrupts data even on 3G!
Has anyone seen this? How do I fix it? Thanks.

Yep overhere also... testing all radio roms but all the same... so far no fix found... we have to live with it...
The kaizer is dead... long live the Kaizer...
... to many problems

I'm in Edge country right now, but will be in 3g in a few minutes as I'm getting ready to roll out to LA, I'll email you from the car to test if the 3g and phone call can co-exist.

I think it has to do something with AT&T's cell towers. I also experienced the same issue that when calls came in my data connection would be cancelled. However one day, out of the blue, the 3G icon was suddenly replaced by an H icon. And it is there all the time! Now I can call and download data at the same time.

Thanks... that's bizzare. H means it's using the HSDPA protocol for 3G, U means it's UMTS, I think now the 3G icon shows up instead of U. (I hope I got my acronyms right). But that shouldn't matter! My phone will go between 3G and H, I think based on the capabilities of the towers. There is no telling what will show up in a given spot.
The mystery remains... Come on, all experts out there, share your wisdom. Could this have anything to do with disconnection settings or TCP settings (done via KaiserTweak)?

I think I just found the answer. Went to KaiserTweak, and selected the Data/Disconnect After setting, which I had set to 1 minute. In the description for that setting, It says "warning.." but you can't see the warning unless you go to landscape mode, which is why I never noticed it before. The warning says that with this setting, 3G Simultaneous Voice and Data will no longer work.
Disconect disabled, and a quick test showed that the problem is solved.

my Kaiser do not work with 3G only works on GSM

Suddenly it had happened; NO 3G nor GPRS data transmission. I can see the 3G sign , but when I make calls the phone disconnects; when somebody call me, he received a message that my phone is off line. Only when 3G signal is on. But when normal GSM is on, everything will be OK. My phone can not get data from the internet, even though it shows that is is connected. I tried all of the above solutions to fix this problem but no helpand sometimes it shows 3g sign but as soon as i try to call some1 all the signals are gone.. I tried to hard reset and try it before installing any software, no help. I tried mostly all available ROMs and Radio ROMs; even the original, but not fixed. I do not what to do. Now, I am using the phone with GSM only, NO 3G. Please help!!!

Hi there nunu,
I had the same problem, went back to the store and nope not a known problem.... So I started to troubleshoot this
1. normal G connection
2. 3G appears or even H
3. signal lost and after 30 sec. the cycle starts again.
what worked for me was the changing the of the radio version. I am currently in the Netherlands and here the NEON_Radinly_1.65.24.36 works fine, I confirmed it by loading a rom with a different radio in it and the result was again the same.
hope this helped in any way...
Let me (us) know.

life is good, but life get's much better with a Kaiser

are you trying to connect with [email protected] / cingular1 ?
this is the kinda information you should have put in your first post
I use the above and have zero problems in Philadelphia

My 3G went out for like a day here (Phone only worked on Edge), then it started working again. Cellular carriers do have outages from time to time. Has it been a long while since it stopped working?

Flash to a different compatible radio. If you do not get 3G/H service back, then you have a hardware issue with your radio, and will need to have the phone serviced.

what newtwork are you on?
have you tried your sim in a different handset?
what happens when running in gsm only mode?
in settings phone network change selection to manual and tap find networks and reselect network (this is known as a manual roam) does this make a difference?

Same here!, im in montreal, canada with Rogers, and in 3g doesnt work, it detects the 3G network, but as soon as i try to make a call or go on the internet it looses the signal and i have to go on GSM mode.
and i'm using LKDV12 but i still had the same problem on AT&T Original rom, and Dual V2.
Anyone?

Major problem --
I have been travelling round the world for a year and have the same problem, Have tried many radios, if I use 3G( wscdma) or auto band then the signal drops everytime i try to make a call, and no data is possible however if I use gsm only data and voice work fine, thease symptoms are on many networks, Chile, Easter Island,Tahiti, NZ, Fiji, Optus ( OZ ), and m1 ( singapore ),
Radios tried
EMO 1.71.09.01
Neon 1.65.24.36
1.65.21.18 ( att )
I even loaded the generic dopod rom + radio and it didnt seem to help.
Is it possible something low level has changed whilst doing all this flashing ?
Or could the Hard SPL affect something.
I always try to buy a 3G USIM in each country and test the sim in a backup G800 to ensure the carrier has enabled 3g data okay.
Phone is Kaiser ( HTC TytnII )
ROM is varied but and usually lorentis series roms -- L26 12 light atm
Symptoms, 3G icon shows but data wont connect, if you try to call radio strength bar drops to zero and cell communications are lost , sometimes reestablishes comms but often needs soft reset to band switch to work.
If 3G icon not showing all calls and GPRS data works Okay.
Personally I would not expect this to be a hardware failiure as many others are experiencing teh same fault and for working hardware to fail in use is more erratic in the failiure mode, but a low level register, or some other type of protocol corruption could easiliy be the cause......
The proven "high GPS current consumption in standby" issue is also present as it seems to be on all Kaisers but afaik the root cause of this was never resolved either .....

my Kaiser do not work with 3G only works on GSM NEED HELP
HI I´m from mexico telcel gsm band and the same problm works on my kaiser tried changing the rom put the htc rom again the radio too

i have the same problem did you make it work how you set a gsm band instead of the 3g on the phone tks for your assis
dr.vogel

I have the same problem. Already had it with WM6.0 original HTC ROM (Finnish ROM, but language set to English). Then sent it to service. It came back, they said they "reapplied software or smth" and it worked after that. Then after 6.1 update again, the same problem (even with the latest updated Radio ROM).
When I set band selection to auto, it picks up 3G or even H but tends to loose it and definetly looses connection to network if I try to make a call. Can't take any incoming calls either.
It works ok when I force it to use GSM (EDGE for data) on Band selection tab, in phone properties.
I probably won't bother taking it to service anymore cause there is no local service here in Estonia, they ship it to Finland and it will take a minimum of 3 weeks...
... so I'm waiting for Xperia X1 and hope it's not as much HTC.

Hardware problem, repair needed and unavoidable to get 3G functionality back.

I have the same problem.
I bought an O2 Stellar (Kaiser) from a work colleague and it worked fine on 3G/Auto on the day I bought it.
The next morning, when I switched on the phone, it had exactly the symptoms described (i.e. it would only work if forced into GSM mode).
My colleague took it back to O2 under warranty.
1 week later, it was returned as 'fixed', but it actually still had the problem, so my colleague returned it again to O2.
Another week later, O2 provided a replacement unit under warranty.
The replacement worked fine, until the next morning when I turned on the phone and had to force it into GSM mode again because it wouldn't work in 3G/Auto mode.
I'm on 3 in the UK and I suspect the problem is something to do with the roaming onto Orange GSM which happens when there is no 3G signal from 3UK. However, on the day each of the units worked, it was switching between 3G and GSM repeatedly because the 3G signal is fairly poor in my office.
I'm now waiting for my colleague to return from his holiday so that he can return this unit to O2 and we'll see if we get another replacement. If we do, I'm very reluctant to actually use it - I think I'll probably just sell it on and get something different. Shame because I really like the Kaiser.

as mentioned before, another thing that you should've tried is to call the helpline and see if there's an outage in your area. I've been experiencing the same problem in a very particular area (3G hand-off to EDGE problem only happens on campus). Tried different radios and problem still exist, so I gave them a call today and turned out that there is an outage here.

In my case, it's not caused by a network outage - 3G works fine on my Hermes in the same locations.
Good thought though.

Relax boys...I have'd the same problem... The only solution is to go with your phone for warranty return. There they will change your TyTN II mother board and all will be ok. IT IS THE ONLY WAY.
PS do the same thing I did http://forum.xda-developers.com/showthread.php?t=418375

i post this thead and the solution
i post this tread an the solution came on tha answer of various of you great ideas i get the solution changing the rom and the wm to 6.1 and the rom is the dutty's it has worked almost perfectly in any wy itested only some install on the gps progrms but no mayor problem tks all you friens for a great support

The same thing has happened to me as well (Orange UK).
Initially I thought that it was an outage in my area as my friends had problems connecting to 3G as well, but their problem has been fixed but I still cannot.
I'll be contacting their tech support dept. later today and I'll post back.

Orange Uk 3G not allowing calls and delayed txts anyone?

hi i have a touch diamond orange variety and when i travel to scarborough uk i dont get calls and will just get a txt 2hrs late saying missed call and i cant send msgs out.
ive tried my htc tytn 2 and thats the same and i tried my bros omnia and thats the same.
i was wondering if anyone else had same problem either in scarborough or anywhere else on orange uk?
ive tried numerous different radios etc
thanks for any help

I'm on Orange in the UK and swapped to 3G as soon as I did I couldn't make any calls, turned out all my Phone settings were changed. On the services tab check Call Barring, Call Forwarding etc. I've gone back to my old sim only because the receiption for 3G was rubbish in my area. Hope you have better luck. tallen3

What do Orange have to say about it?

They blamed the phone, I managed to change the settings myself, Orange were less than helpful but probably about average for a phone company.

I was asking the OP!
But yes, unless you can actually see the mast with your naked eye 3G reception is a known issue with the Diamond. I have set mine to GSM only.

Orange 3G works fine for me without seeing the mast - even indoors. But that can't be the problem because if 3G reception is to weak or not available then it should revert to GPRS or Edge automatically and will still allow calls.
To the OP - is it all of Scarborough or just particular parts? Does it happen anywhere else in the UK?

The problem I have with 3G on my Orange Diamond is that although the phone just clings onto 3G indoors (about 1 mile from the nearest 3G mast) it drops down onto GSM as soon as I make a call - with associated momentary call interference - and drains the battery a lot quicker on standby (I'm syncing with Exchange every 15 mins 07:00-17:15 Mon-Fri).
If I'm 50 yards away from the mast I get HSDPA, which is handy when I'm in my car queueing at the tip, not...

hi i finally had a call from orange they now say its scarborough that doesnt have enough 3g masts and they have planning permission in for some more.
its strange everywhere else is fine even when i have lower 3g signal than scarborough.
they recommend i leave my handset on auto which doesnt work so was told everytime i go to scarborough manually turn phone to 2g.
not a perfect soloution, and i wonder why scarborough is like that? ever since they activated the hsdpa.
thanks for all the comments and suggestions.

If your phone won't auto switch between the two then it is faulty and Orange should sort it out shouldn't they? Or is it not their phone?

well it does switch between but i have a two bar 3g signal and it doesnt work for calls as explained and therefore wont switch to 2g.
thanks for all your help btw its not just my fone its most win mobile fones that my family and friends have.

Missed Calls when connected to GPRS Internet

Hello all,
Have any of you guys come across this problem with your X1...I was connected to the internet via GPRS earlier this afternoon doing a little browsing and have now received 3 missed call notifications which were made during my browsing.
Does the phone not receive calls when connected to GPRS...very annoying.
I'm using the Touch X 10.1 rom by Smaberg but don't think that is the problem...any ideas!!!

some phone operators with older hardware in their end don't support call and gprs at the same time
not really a phone thing

Thanks for the reply...I'm on the Orange network so I thought they would have been up to speed with technology incorporating call and data at the same time...

Same issue here.
I'm pretty sure that GPRS and voice calls can't work at the same time because of the 2G network, but thought at least the voice call would interrupt the data session.

That's my understanding. 3 & 3.5G allows voice and data at the same time.
but on 2G it's either GPRS or voice... that used to drive me crazy with my Prophet too

Ah, that makes sense...I usually turn off the 3G to extend battery life so that would be the reason I missed calls...may turn it back to 3G if I'm doing a session of browsing in future...
Cheers

even with my 2g himalaya I didn't have any problems with both calling and gprs
it was why gprs was interduced to replace the slower and older gsm dataconnection
which worked the same way as an analog modem which blocked of cause
of cause only class A gprs devices support that
http://en.wikipedia.org/wiki/General_Packet_Radio_Service#Hardware
but all these phones today are that
problem is that class A is required in both the phone and the operators network hardware

Try with RADIO ROM 1.16.
Problem with this rom is apparently solved.

I am in 3G.
I have no problems when putting my sim in my tp2. And talking while surfing.
And i am not the only one. No one has givein a reason as to why.

Uh..unless you changed you radio settings to "WCDMA only" you should be able to talk and surf.

It should work. I do it all the time, but it is network dependent.
In case it works on your TP2 i suggest you check your settings.

Hey big guy are you using a t-mobile nexus one on AT&T? Or AT&T N1 on T-mobile? That used to send all my calls to voicemail while I was on the intarwebs

Incorrect. "WCDMA only" is still UMTS/HSPA (3G/3.5G in consumer speak), therefore you still get voice/data at once. I can only conclude that you're under the assumption that UMTS/GSM work the same way EVDO/CDMA does. On an EVDO network, all data goes through the EVDO network, while voice stays on 1xCDMA, because EVDO is an addon to 1xCDMA.
UMTS and GSM are two completely incompatible technologies that only share GSM backend features and a SIM card. The circuits in the phone are separate, the antennas on the towers are separate. You're either completely on UMTS for voice and data (inc. both at the same time) or you're completely on GSM (for voice or data but not both at once. In fact, if you're locked on to a strong UMTS signal, the parts of your phone that handle GSM shut down for power conservation and only wake up when your signal drops to check to see if you'll get a superior signal over GSM. It will do this periodically, but won't stay active for long unless your UMTS is so bad that you won't be able to hold a call. THEN your phone powers up and maintains the GSM radio, while putting the UMTS radio on standby, only powering it up momentarily to look for a better signal.
The only time you have GSM and WCDMA/UMTS powered on at the same time is during hand-offs from one network to the other. That's why staying in areas where you bounce between the two kills your battery so quickly, the radio is drawing roughly twice as much juice as it normally does, plus it's computing which one will do the better job for the moment. Even then, at that time, the phone and its OS will be using only one of the networks at a time, and if it's UMTS, you'll be able to hold a call and surf the web.

Hey, sort of same thing just happened to me
in my case using GSM Auto (prl) or WCDMA prefered I can connect to HSDPA but GSM is in emergency calls only, weird.
but I can do both on GSM only (GPRS/EDGE)

Re-flashed to official release of 2.1 same thing.

i use voice and data on my nexus at the sme time every day. it just works. as long as you have a 3G symbol next to your reception bars, then it works.
i dont know what you could have done to break this. can you demonstrate to us what you are doing that is not "working"?

I am connected to 3G network. Call comes in. I can not browse on the internet. While i am on the call i go check settings and i have droped to GPRS. As soon as i hang up i go back to 3G (HSDPA)

Have you ever changed your build.prop file at all in the past? If so that's the problem. Change to hsxpa=2 to fix it.
If not then I have no clue.

I have no problem on my TP2.

I use it often too but today I was unable to it. Hopefully its because my area is being updated to hsdpa+

i think i have the same problem. 3G drops during voice call, doesn't connect during the call. reconnects after the call ends.
stock nexus one tmobile FRG83D

When you have bad reception, that's what happens. Normal and expected. During the call it won't re-negotiate 3G, only when the call ends.

Yeah, that is normal and it really sucks when you're on a long call. Once you lose 3G signal it's gone for good. I don't know if it's a network problem, or the phone, but it should be fixed.
