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 got my G2 a couple days ago and I must say this phone is amazing..coming from a g1 I had for 2 years its quite an improvement. The only minor problem I'm experiencing is with the radio signal..most notably in my house..on my G1 I always had signal and internet connection. Now with the G2 I constantly loose connection all through out the house and the only way to get it back is to switch the airplane mode on and off and it picks it up right away, only to go away a few minutes later..I don't seem to have the problem anywhere else.
Was wondering if any of you guys can shed some light on if there is a way for me to figure out why the signal is so random in my house and it was ok with the G1. And why airplane mode seem to fix it for a short while.

did u activate the sim card that came with the phone or still using the old one?
I'm still using the "old" one still but considering I got it 2 months ago I wouldn't think its a big deal unless the sim that comes with the G2 is any different?

I asked because i was told to activate the new sim card to avoid issues likes the ones u seem to be having.
I was told to replace the sim card as well. After doing so there was no change in the reception of the unit. The downside is that the sim card does fine in my Vibrant but does not work at all in My Nexus One. Tried two different new sim cards and each time the Nexus One refuses tacknowledge it while the G2 and Vibrant do. I have found no difference in signal quality or strength with the new sim. The new sim card has a much smaller gold contact area and that area is a slightly different shape,
I went ahead and activated my new sim card to see if maybe it'll fix the problem..ill let you guys know how it goes
Sent from my T-Mobile G2 using XDA App
Changing the simcards will not work. If I put my simcard in my iPhone 3G or my G1, I'll have 2 or 3 bard with 3G, but with the G2, It switches up all the time, from Edge to 3G or no data at all, with 1 or 2 bars. I also have five other family members that also have T-Mobile phones and their getting about 4-5 bars on their phones. So it's not the sim or a tower issue.
There's cleary a problem with these phones.
This mourning I woke up and found the phone with no service, no bars. I reset it and came back, this afternoon I left the phone on my bed, came back to it, and again no service, it seems the service keeps going out for no reason.
Another is, I live in a big building, when walking in and out the building, my data connection will drop, or sometimes I won't even have any service, and again the only remedy is to restart the phone to get service back, airplane mode won't even fix it.
Yea the new sim hasn't really fixed anything at all..

damn i was about to try that... guess i'll keep waiting... maybe an OTA radio update will help this cause it's really getting annoying.
I don't have a problem with my G2 dropping signal completely, but I have noticed that my 3G is very spotty. It's probably because I was spoiled the the MyTouch Slide's 3G only option.
Yes, I've noticed that the signal isn't quite as good as my G1. It's seems to be about on par, if not slightly below my friend's Vibrant.
But remember, the G1's radio really sucked once upon a time. Radio updates. They will come. Every phone that has OTA updates always gets new radio, in my experience.
I'm on my 3rd G2, mostly for manipulating the purchase price, and have noticed on this 3rd one that the spring is looser than the first two, the phone resets itself and often, and I'll loose data even though it shows I'm connected. This will happen in edge or hspda. I'm taking the phone back tomorrow.
Crappy thing I just put the ZAGG complete invisi shield on it. WIll Zagg comp me another cover you think?
If only Tmobile would activate the UMA calling over wifi. This would be the perfect phone with perfect service.
I am going to call tmobile in the morning and see if I can get any word on the UMA release. If not, the phone may have to go back.
I'm having the same problem, not at my house but at a local ihop that happens to be walking distance from where I'm moving in a week. I tried a reboot, airplane mode, even pulled the sim card and nothing worked. I got signal back once I left, but since it's right by the new place I would like to not have to deal with this.

well ive been searching around and i think ive found something that could help..
if you dial *#*#4636#*#* you will get a little screen of information about your phone, go to phone information, under phone information scroll down until you see select network type, the network should be automatically set to "WCDMA preferred" ive been playing around and i set mine to GSM/CDMA auto (PRL) and since then (about an hour roughly now) i havent lost my signal or connection in the same spot i was loosing it in my house every 10 minutes or so. not sure if this fixed anything but so far so good. definately will let you guys know if it continues to be good or if it doesnt stay consistent.
heres some information also in case you dont know which one would be best for you.
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best. (Maybe the Samsung Galaxy S will take advantage of this???)
Unknown - If none of the above fit or the phone is acting weird as far as connecting to the carrier, you will see your preferred network type is set to this

Having same issue with the signal. Swapped for a new sim but still the same. Sometimes service drops completely and I have to go through the settings menu to search for a signal in order to get some reception

phone came in wcdma preferred stock... I came by that option too but I would much rather suffer with spotty signal [HSPA] over Slow edge speeds...
that said I may turn on GSM only when I'm indoors with little coverage, should save a lot of battery.
is there a setting that forces the G2 to go for the G3 or H setting instead of the edge? I live in an area where my phone can get both and it always goes for the edge signal instead of a weak H signal and the edge is soooo slowww.

*#*#4636#*#* then phone information, then scroll down and change the drop down from auto to wcdma only. Only problem with that is if u go to an area with no 3g, u get no service and have to change it back or go under the settings and wireless to enable 2g connections

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
Hey guys, I'm not sure if this is normal, if it's my provider's fault, or if it's my phone's fault, but from time to time (maybe once or twice a day) my Samsung s7 Edge will pause when I'm sending a message and wait for 10-30 seconds before connecting to 4G (from LTE) and finally sending it. What do you guys think, normal or not normal? I don't remember if this would happen with my old phone so I guess it's hard for me to judge whether this is a problem with my provider.
Just to clarify, my "issue" is with the 30-second lag that happens when it's switching from LTE to 4G. Not sure if this is normal or not.
Thanks!
Those are the same thing LTE 4G. Maybe switching from 3G?
I've recently received a carrier update which has resulted in the LTE logo being switched to 4G. You sure it's not switching from LTE to 3g?
How can I tell if it's 3G? I'm pretty sure I saw LTE and then after the "lag" it said 4G. My phone is also unlocked, not sure if that makes a difference in whether or not I receive carrier updates or updates straight from Samsung.
Btw, this happened once when I was sending a text as well; it took like 30 seconds to send. I don't text much so maybe this would happen more often if I were to text more. Is this normal?
It will say 3G or H.
Ok it just happened again, and actually it was on 4G and working great and then I sent a text and it switched to LTE and I got a thing that said that there is no signal and to wait for a signal. 30 seconds later the text sends. Hmm...
Hi, my issue is the fact that my s7 edge is using LTE.
When I switch on the LTE I can't make fine calls.
I am in UK and my fine come from US.
So to fix this how can i remove lte and choose the normal 4G?
Thanks
I have a 6P now and am trying to use it with straight talk as of last couple days. When I used the CDMA sim it seems to only get LTE when not making a call. When I try to use the internet during a call, it loses data completely and an explanation mark show up top near service bars. Now I switched over to the GSM sim and in spots where I used to get 4G with an Alcatel phone, it switches to HPSA (which creeps). Does the 6P not even have the radios for 4G? I thought it was supposed to be compatible with just about every 4G tower.
It works fine, however, with straight talk you can't use the internet while on the phone unless you use WiFi.
