It seems sometimes on my vibrant that I am able to use 3g and be on a voice call at the same time, and sometimes not. Anyway to make this consistent? On nero v3 if that helps.
Are you sure that you are indeed on 3G?
I posted this while on a call
It depends on the signal strength

I have been informed you can use voice call while on 3g but not edge. Blah

A few times today, when on a call, my 3G connection drops and a baloon pops up saying "connection lost, please reconnect after your call", or something like that. Of course as soon as i hang up, the data connection comes back... but this seems rather annoying.
Anyone else seen this?
That happens to me all the time when I'm surfing the web and a call comes in. The Hermes doesn't have the ability to have data going while voice is active.

Hmmm.... cingular better update thier web site then.
Use this all-in-one global handheld for email, simultaneous voice and data, and other wireless application needs at broadband speeds.

It used to work for me on my 8525, but not anymore.

this is partially false... The 8525/hermes will keep a data connection active while voice is going in 3G... but voice and data will not work together while in E.. And if you are in a call and your 3G signal becomes to weak it will switch to E causing your data to drop and your phone can not reconnect to 3G until the call is ended. The only time this really ever happens to me is when i am driving, but thats because of few weak spots here in st. louis.

I'm using radio version 1.54.07.00 ans when I am connected via 3G (says H) and get a voice call then it disconnects my data session. Very annoying. What radio are you using that will allow simultaneous voice/data on 3G?
I'm on ATT/Cingular out in Las Vegas if that makes a difference.
Hi everyone,
I'm on a fringe coverage area with AT&T. I have a pretty new sim card, but I noticed that I get a lot of dropped calls while on 3G (or H). I usually get 1-2 bars on 3G. Shouldn't the call I'm on, hand-off to Edge if the signal is not strong enough on 3G? Right now, its dropping the call altogether on 3G with no fallback to Edge. Is the Xperia's radio to blame for this?
Thanks!
i dont know who is to blame but if your on the fringe as you say, you should just manually set your device to use edge/gsm.
it will save on your battery and have less dropped calls. otherwise, you phone will keep bouncing between signals.
i also have the same problem and i am curious of the answer i dont want to lose 3g all together but i have 1 bar in my house and drop calls also.
Has anyone on AT&T tried to flash their xperia with the Raphael radio? Is the signal alot better?
not just exactly the same problem here, but similar (according to the network). at home, i have no 3g coverage and manage to get edge at best, problem is intermitantly my voice stops, even though i can here the other caller perfectly, the phone still keeps between 2-3 bars of signal, and i can even stay on the call over 30 seconds after it happens. the other caller can just hear like a dead noise. the network has me testing the 3g thing for the next couple of days though.
PS. this also happened with a K850i and a K800i
I got an email while on a call without wifi. I'm in dallas. Anyone else getting data and voice now?
Has been possible since the beginning of time as long as you are on 3G
I concur. ↑

Really? I've never been able to do that until recently.
Usually when I'd start a call I'd lose the 3G icon and if I received email while in call it wouldn't show up until after I hung up.
Couldn't mess with data without wifi.
Used to do this on my cliq and G1 as well...
Odd.
Also been doing both (on TMob 3G) since February...
Any gsm phone can do that, but it is impossible for cdma
Your phone may have been set to WCDMA only up until now.
chalk that up as a win for GSM and a lose for CDMA

WCDMA is 3G, it has nothing to do with CDMA
In a weak 3G signal area, the phone usually does a handover and transfers the call to the GSM network when the 3G signal falls under some threshold, and GSM doesn't support simultaneous voice and data (icon disappears while on a call)
maybe you have better 3G coverage now and your nexus doesn't need to go the GSM route
I've noticed problems with using data and voice together too. What seems to happen is that it works ok at first, but the instant you lose 3G it never comes back until the call is over, no matter how good your signal. Very frustrating when trying to use your data while on a long call.
Both AT&T and T-Mobile (as can any GSM carrier worldwide) can do voice and data at the same time as long as your phone has a "3G" connection visible while on the phone call. This has always been possible.
What you may see happen is that if you wrap your hands around the bottom of the phone during a call, the signal may drop to "E" or Edge. You can't use data and voice at the same time if your phone is on Edge.
To alleviate this, use a wired or Bluetooth headset, or hold the phone with your fingers rather than your whole palm.

Have you ever seen my problem where once the signal drops to Edge it will never go back to 3G? It doesn't seem like normal behavior to me but it seems to always happen when I need my data during the call. I've been stuck on multi-hour calls where my phone refused to go back to 3G almost from the beginning, and then the second I hang up the phone goes right back to a 3G signal with full bars again. Very frustrating!

the ATT 3G network is not setup to do handoffs from gsm back to 3g. it currently will ONLY handoff from 3G to gsm during a call, and if you are still on your call, it will not switch back until you hang up. in the future this can be enabled both ways. tmobile apparently is setup the same way for now. so you're experience is normal until they reconfigure their network.
Actually it depends on the phone hardware. It IS possible to use GPRS and voice as well if the hardware supports it, its not only something available on 3G/UMTS/WCDMA. There is a pretty even split between class A and class B phones these days, you should look up the specs of the phone you're using.
Nearly all 3G devices allow you to use data and voice together since it isnt timeslot based and so voice and data is logically split and not time divided. This means you dont need specially designed hardware to do it, just the processing power to do it.
Class A
Can be connected to GPRS service and GSM service (voice, SMS), using both at the same time.
Class B
Can be connected to GPRS service and GSM service (voice, SMS), but using only one or the other at a given time. During GSM service (voice call or SMS), GPRS service is suspended, and then resumed automatically after the GSM service (voice call or SMS) has concluded.
Class C
Are connected to either GPRS service or GSM service (voice, SMS). Must be switched manually between one or the other service.
@kam187, thanks for that. I've been with T-Mobile since they were Voicestream, about 10 years now. And I thought I was making voice and data connections with my Nokia phone years ago, before their 3G rollout.
Here is the last phone I used before going the G1 route.

Yep E61 is on nokia's list of Class A devices:

I'm using Cyanogen Mod 7.0.3 with 2.6.32.28 kernel. Each time I make a call, the data network symbol disappears. This is not the case when I am on WiFi. It does not bother me too much, but if it is a fixable bug, I would like to know how to fix it.
If you are not on hspa you will loose your data when ur making a call.

I often miss calls when I'm on 2G saving battery and my friends are chatting up a storm in Whatsapp groupchat for exactly this reason.
nod the problem is because you're in 1 or 2G, you said when you use wifi the problmem does not exist, that is because there are separate line between data and voice. Like other has noted above, try to stay at 3G which does have separate data and voice so you won't loose data call when you're doing voice call.
I notice that happens to me sometimes too. Always wondered why sometimes the data went away and sometimes it didnt. Thanks for some clarification!
So i had setup and tested both apps at home over WiFi and the talk quality seemed perfectly fine, but I was a bit disappointed when I went out on a work day and tried to make some calls over 3G, it did not work out so well. It also does not help that I live in such a rural area with lack of coverage in some areas, but I can say that voice calls on my phone come in crystal clear. I've had either static, echo or bad delay time in voice transition.
So I'm wondering what other people have experienced trying to make VOIP calls over 3 G instead of WiFi, and if anyone has any tips, other than just use my phone.
I think the apps need better compression for when they work on 3G.

It really just sounds like a carrier issue. I use groove IP with att grandfathered unlimited data and when I'm at work call quality is considerably lower because of spotty signal. When you say phone calls come in clear do you mean a regular cell? You can have a strong cell signal with bad data connectivity
