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.

hello, I have a new t mobile htc one I got as gift (never opened). My old phone was an unlocked samsung galaxy nexus using a tmobile prepaid sim. I resized this sim to fit the htc one and everything worked fine( full bars for signal). Problem with this sim is that I could not make wifi calls. So I called tmobile and had them activate the new sim which I got with the htc one (Same prepaid plan, no data). i can now make wifi calls. Problem is once wifi is disconnected I only have 1 bar. If I attempt to make a call all bars raise in full, even if i attempt to check my balance the bars automatically jump from 1 to full and back to 1 bar after i see my balance. Is there a setting i need to change or is this normal? i am worried I may be missing calls like this. (All this happens when the wifi is disabled)
Sorry if the post is confusing, I tried to provide all the details but will be happy to provide anything else if necessary.
Thanks!

This happens with me sometimes as well...if it is in LTE mode, the signal bars are less...1 , sometime 2, and sometimes 4... as soon as i make call, the data connection is OFF for that moment, and the signal bars are full....as soon as the calls end, the data connection is activated.... the bars are less again.... try changing the data connection modes from LTE to 3G only and to 2G....and see what happens

Awesome this helps. Thanks. In my situation I have no data plan setup. No need for any internet on my phone atm. So all I use this phone for is calls and an occasional sms. Will I have a longer battery life if i disable lte and have it on gsm only? Would the call signal drop?

i am not sure, but when you dont use Mobile Data on your HTC one, there is no need to select the LTE mode.... you can select the other option always. and it might save battery as well....."might"
You will definitely save on battery if you switch to 2g if you don't use data at all. Switching to 3g frequency takes more battery even when there's no data connection.
I switched it to gsm only then disabled mobile data. Full bars now. This should work. The next option is wcdma which i dont think tmobile uses.
I'm having some issues receiving phone calls when I'm in 4G mode - I'm aware of the fact that voice over lte doesn't work yet, however in my understanding the phone should quickly switch to 3g mode and accept the incoming call, right?
Apparently my P7-L10 has trouble with that. It just doesn't switch, and the incoming call goes to voicemail.
Is that normal? Is there any fix to make the device switch to 3g mode quicker upon a call?
Running B135 rom, rooted.

I'm having fine calls when I'm on 4G. (Milan, north Italy). Perhaps your city has too few 4G antennas and doesn't have stable 4G signal so it switches back and forth to 3G while you're having a call?

I don't think that's the issue, 4G coverage here is pretty amazing.

Forget what I wrote, I forgot that voice calls don't have to do anything with LTE, lol.
Anyway I'm having fine calls with 3G or 2G, have you tried doing a nandroid backup and start over to see if the problem occurs also in fresh state?
Fine calls with 3g or 2g here as well.
Except when I'm on 4G - nobody can reach me, it all goes to voicemail...
I could say I started fresh - I did a factory reset and a clean wipe 3 days ago, but I haven't noticed the issue untill yesterday.
On a French, people reported issues with calls in 4g covered area, but it seems that the problems come from network, not from the phone. The issues appear only in certain areas with one operator, and some other phones behave in same manner. Perhaps you need to check with another SIM card from another operator.
hello,
I encounter the same problem receiving my incoming calls in automatic mode 4G 3G 2G redirected my mail. When I'm on automatic 3G2G no problem.
I'm B133 update. 4 months no problem. Since mid-October the problem occurred.
My operator is Virgin Mobile. P7 smartphones, antennas or operator?
The rocker 4G 3G to receive calls no longer made. Tried my sim card on a S5 and a LG G2 and the problem is the same.
After several calls to my operator solution but not another concern, I have to connect data to receive my calls 4G 3G 2G automatic.
I'll try to go B121 update or réinisilisation P7.
If no solution change operator before trying their sim card lent by friends subscribers home.

when I pick up the phone my phone says 1x and I dont have data. i have hd voice enabled. I had hd voice enabled on my lg g4 and my nexus 6 and could use data while on a call
Enable VOLTE on your phone and MyVerizon. VOLTE must be anabled on each phone.
This is an issue with all new phones. They only have 1 antenna (older phones had 2, one could use data, one could use to make a call) so, you can only be connected and use 1 service, either data or talk. Advanced calling, HD voice, VoLTE...whatever you call it, that is making a phone call over data on your 4G network and thus you can use data at the same time as its using a data connection to make the call. But if youre in 3G, it uses your antenna for a cell call and no data is available then. PLUS....if you're on a HD 4G VoLTE call and switch to 3g (leave the 4g signal), your call with instantly... Drop. The idea is, in 5-10 years, they will turn OFF their 3g network and it won't matter.

I just bought my note 5. Its the dual sim version. So the first few days was days.... i started having difficulty with making outgoing calls... texts are fine... its like 1 out 10 calls would push through. So i rebooted my phone thinking that it might resolve the issue....unfortunately it did not. Then a few friends sent me a message that theyve been trying to call me and it always says im out of coverage are... the whole time this was happening I was connected to LTE. When i changed my mobile network setting to 3g/2g .... then calls came in and went out. Has anyone have the same issue with note 5?
The international versions don't have VoLTE enabled. Not sure how to enable it. Mine also doesn't have WB-AMR (HD Voice) enabled either.
Thus, calls need to be switched through the HSPA network and can't be routed while connected to LTE. Essentially when making a call your phone switches and tries to register on HSPA, quickly.
The problem im facing with my Xiaomi Mi5 is that whenever i switch the data connection from Sim 1(Jio 4G) to Sim 2(Airtel), sim 1 loses the signal and remains unavailable for calls both incoming and outgoing. I tried to change the preferred network type and swapped the sim slots but nothing seems to work. If you guys can help plz do so.
Note: Sim 1(Jio 4G) is 4G only network it doesn't work on GSM or WCDMA.
the non-data line only does 3g, or 2g if 3g isn't available..

I'm also facing the exact same problem!!
But I think it is operator-specific because Jio 4G does not support 2G/3G networks but only 4G LTE. However, Airtel 4G on the other hand switches to 2G/3G networks when not using data services.

Thats what I thought until I checked it on Asus Zenphone 2 it works perfectly fine with other sim on 3G and Jio on 4G.
When I'm using data on 4G on Mi5, the other sim gets 3G network but fluctuates very much and if you change it to 2G only, it will automatically get back to 3G network.
