why when I'm calling someone and talking with them I dont have 3G network, and I can't surf the internet? but only when I talk after I close the call I can surft the internet... Its the same at you also ?
For me while I'm on wcdma I can use the Internet but while on Gsm I can't
in my city is like H+/H everywhere..but when I call someone I can't do notjing
in 2G or 3G network,you can't use network-based internet while a call is in progress.but you can use wi-fi connection during a call.
Hi
I'm trying to get the best Internet connection on my phone. My carrier doesn't support voice over LTE so if I set the Network mode to LTE only I got no calls incoming or outgoing.
The other options I have are 2G only or 3G only, which makes my LTE data plan useless.
Best option is to have it configured to 2G/3G/LTE, but the problem is that when I'm usually stuck with an excellent 2G connection (with useless internet), instead of a not lousy/not great 3G connection, which still has better Internet speed and stability than 4G.
I'm looking to have my phone only see 3G/4G and not 2G, but I don't have a network mode for that. How can I enable the network mode I require?
I'm rooted so if I can enable it somewhere in the system, that is an option.
Thanks in advance
I recently noticed that in my OP3T when someone calls, mobile data gets disconnected while on 4G network. When a call is initiated, 4G immediately changes to H+ and stays there for sometime(10 - 30 secs) and then disconnects completely. And when the call is disconnected, mobile data reconnects showing 4G.
The call and data are being used from the same sim (primary). To make sure that second sim is not interfering, I disabled the second sim and tested above scenario again and the behavior was same, data disconnects on call.
Is it an expected behavior or is there any issue with my mobile. As far as I know call and data cannot work together on 2G network, but on 3G/4G network it should work simultaneously as long as both data and call goes through same sim.
P.S. The 4G network I am on is not VoLTE. I am on OxygenOS 4.5.

If it's not VoLTE, it'll drop to a 2G signal (H symbol) or 3G (H+) while on a call, precisely because you don't have voice over LTE.
Yes, it's normal and will be fixed when operators start supporting VoLTE.
So yes, you're not the only one that's experiencing this.
GPS issues:location not working during 3G call only
I lost my GPS signal when I make or receive calls on 3G network
GPS signal not updated during 3G call till end call
With AT&T shutting down it's 3G network in a few months I was wondering if anyone had been able to get AT*T's voLTE (HD voice) activated so we can still make voice calls on the network. I have the AT&T model (and am using a tracfone AT&T sim), and "search" in the settings does show an entry for "enhanced LTE services" but selecting it just takes you to the same spot as the "more" entry and there is nothing useful for voLTE. When making a voice call data drops out of LTE, down to "4G".
Using a t-mobile sim (via tracfone), defaults to voLTE, verified also by surfing during a phone call, and LTE symbol staying on the whole time.
Hmmm weird, I can get voLTE with another AT&T MVNO (unreal mobile) by default, with no issues (also tested by surfing during a call and having LTE symbol stay on). I was not aware there could/would be differences in voLTE support among MVNOs
