[Q] On Verizon SMS and LTE

On Verizon, was streaming video on LTE not Wi-fi and simultaneously receiving text messages. There was no interruption in streaming on LTE. How is this possible? I cannot use LTE and voice simultaneously yet, but isn't the CDMA radio for calls and texts the same? Why does SMS work while using LTE, but voice does not?

[Q] Poor call connectivty under wifi network

Nexus 6 - When wifi is enabled on phone under wifi network, can't make / receive calls. Callers are unable to connect to my number. Further, don't get any missed call notification for such missed calls
If wifi is disabled on phone, everything works fine.

cant receive and make calls when connected to LTE

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.

Indian Users Note 5 N9208 Duos VoLTE WiFi Calling

Hi, I wish to understand if WiFi Calling is supported by Jio on Note 5 Nougat. I do get VoLTE and its working flawlessly but there are certain areas where network is very bad but I have good WiFi connectivity.
If I enable WiFi Calling incoming calls are there but can't make out going calls. I can't really confirm if there is change in audio quality for incoming calls using WiFi calling because I'm not even sure if its working since it shows no new icon.
My wife has noticed change on her iPhone 6 Plus with WiFi calling but I cannot make sure if there is any difference.
With my wife WiFi calling on she is able to make incoming and outgoing calls both. She too doesn't get any new notification or icon confirming voice call is being routed via WiFi Calling.

MetroPCS: incoming calls are not getting through when wifi is connected

I'm experiencing a weird issue on MetroPCS network, sometimes after phone was connected for a while to a wifi network incoming calls are not getting through. The caller hear ringing and eventually get to voice mail, but the phone does not ring, nor it shows missing calls. If I call someone from the phone, then it fixes the incoming calls issue (or if wifi disconnected).
MetroPCS has wifi-call feature, but the phone doesn't have it (right?) is that somehow related?
