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

I've got a T-mobile UK touch plus.
Currently, if I am using the data connection then all incoming voice calls are being sent to voicemail. This occurs with a GSM connection, which is part of the spec and is fine, but also with the 3G connection, which should allow the incoming voice call through. I have spoken to t-mobile and they acknowledge this problem and say they are working to fix it.
Is it likely there will be a fix for this? Is there a radio ROM already available that fixes the issue?
Sorry if this has already been covered - I searched with a pretty wide variety of terms and didn't find anything conclusive.
I have the same phone, same network... and it still rings while i have the "3g connected" symbol (3g with two arrows pointing left and right) showing.
Havent tried while connected to GPRS cuz im not sure how to force it into G mode while im near a phone.
Sorry, I should have been clearer - the phone will ring with an unused 3G connection, but not when data is actually being sent/received. This is the behaviour you would expect from GSM, but the 3G spec should allow voice calls through regardless of data - my Vodafone v1605 has no problem with this. T-mobile say it is the device not the network, I just wonder how likely I am to get a fix for this? It could be a problem with activesync using the data connection quite frequently.
A good way to test it is with google maps, or something that will maintain a constant connection, then call your phone. 3G should put the call through, but it will be rejected to voicemail instead.
FYI to put into GSM mode;
Settings>Phone>Band>Set top option to GSM, leave bottom on Auto
same problem here. but i only expreienced that randomly
i know that gprs can not handle data and voice. but 3g should, right?
Yes, 3G should be able to run voice and data streams simultaneously without any problems. I'm surprised there is not more interest in this because it seems to be a pretty major problem with the device if you cannot receive calls while browsing or otherwise using the data connection.
Me too
I experienced this too. I have an direct HTC Touch dual rather than the t-mobile branded version but I'm using a t-mobile sim. I use Exchange Activesync and am missing calls all the time.
fwiw, i experience the same with a Nokia e61 on 3-AT network with exchange active.
It seems that T-mobile have fixed their network today to allow calls while using data. Bonus.
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. ↑
Sent from my Nexus One using XDA App
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.

Hey guys, new to the xda forums after lurking here for the last two weeks after getting my N4.
To fully describe my situation, I'm still in college and on most college campuses, signal is very shaky while strong Wi-Fi exists everywhere. Therefore, I initially thought GV + VoIP would be a great option if I dont have signal. However, I'll also be traveling a lot this year in the summer and in those cases, I'll be relying on Tmobile data (yeah...not sure how reliable that'll be in a lot of areas in the U.S.) so I'll probably want to call using T-mobile signal. Being the phone noob that I am, I'm unsure if GV + VoIP will allow me to use the wi-fi in campus to make calls during the fall + winter and also allow me to still make calls with the Tmobile minutes I have in the summer when wi-fi is shaking and I don't really want to trust in Tmobile data strength in a lot of rural U.S. areas.
So TLDR: does GV + VoIP have an easy option to switch between using VoIP with wiFI and disabling VoIP and using carrier minutes to call?
Thanks in advance and sorry if it's a stupid question haha
Use grooveip. You can try sipdroid also but grooveip is better I think.

Use groove ip and set it to only use while on Wi-Fi. Problem solved
Sent from my Nexus 4 using Tapatalk 2
I normally use Talkatone (a Groove IP alternative better IMO) and turn on airplane mode and turn on WiFi. I have T-mobile but I only use it as a backup for when I find I am not getting my WiFi signal for the hotspot I always carry with me. So if I need to make a T-mobile call I just turn off airplane mode and use the native dialer to make the call.
i am considering project Fi.
But where i live there is not tmobile signal, my friends come here with tmobile homes and they dont get signal(they live half a mile away).
Sprint coverage map says that there is "fair" signal.
so i was wondering if with project FI i dont have signal at home, the nexus 6p will switch to my wifi network and i will be able to receive and make calls?

I activated my Project Fi sim earlier in the week. T-Mobile is not strong around my house (I had to switch to an AT&T sim when I was with StraightTalk) and I'm not sure about Sprint. So far, while I'm at home, the majority of my calls are using my home wifi. I haven't had the chance to test a continuous call as I'm driving home to see if it switches to wifi, as Google indicates it will.

Yes, Project Fi uses WiFi for calls and texts when you are on WiFi.
Honestly tmobile wifi calling isn't even that great also. I am only able to get edge in my house with them and wifi calling enabled. I tried calling my phone 15 times and 2-3 times it didn't go through (it actually RINGS but my phone doesn't ring or indicate someone called, and the phone I'm using it rings and goes to voicemail) Wifi calling is at it's infancy I feel like.
I had a tmobile lte booster installed in my room for a year and it BARELY made a difference, still got 0.3-0.5 mbps speeds on their "lte"
Fast forward to last month they finally came out with a lte booster that ACTUALLY works, the previous one came was trash.
If I were you, I'd get tmobile and get the NEW lte booster, because the old one gave me 0.5 to 1mbps at it's best and the new one gives me around 7-10mbps on speedtest. Sprint has horrible signal, I would think their "Fair" signal means horrible reception.
Or just go AT&T and verizon, you get what you pay for..... they are much MUCH reliable than tmobile and sprint.

Note that T-Mobile Wi-Fi calling has nothing in common with Project Fi Wi-Fi calling, which works perfectly.
I seem to only have had one wifi call at my house with Project Fi that I've actually noticed / remembered. I have no idea why all of them don't come in / go out that way. I have a good cell signal too. But, my wifi is strong on 5 Ghz and my bandwidth is about 88 mbps down / 12 up. I only noticed that one time I got an incoming call that said something to the effect of "using wifi network name." I've confirmed the settings in the phone app are set to use wifi calling too.
WiFi calling works perfect at the house. Have very limited cell signal with every provider, so I put on Airplane mode + WiFi and zero issues?

Yeah I was just mentioning how bad tmobile is in some areas. But if you have their new lte booster, it works great. The older version barely made a difference. Came from 0.5mbps to 7-10mbps consistently
I mentioned it also cause they told me to try their wifi calling last year and it was jist decent, I still missed calls without knowing people actually called
