Have 4g data, can receive and send text, but cannot dial out or receive calls.

Hi Everyone!

Here's the back story. I have an unlocked note 2. I've been using wilsons ROM for over a year and decided to switch to Cyanide a couple days ago.
Download all the files, everything went fine during install. Booted up normally. Got everything set up. Great right!? Everything was until I unplugged the phone from the charger and it started playing a notification and would not stop. So I rebooted the phone and from that moment on the phone will not see the cellular network. Data is there, and I can send and receive messages, but I cannot dial out or receive calls.

I've gone to VZW and picked up a new SIM - same result.
I've tried restoring backups - same result.
I've odin'd back to full stock out of the box condition - same result.
Unlocked the bootloader again and tried reflashing the ROMs and the same result.
Any ideas on how to fix this? Could it be a hardware issue? Change antennas?

** Cliffs - Unlocked bootloader Note2 - Installed Cyanide, set everything up, rebooted and lost cellular network connection. Flashed all the way back to stock, nothing changed.

Any advice is welcome. I'm stumped as to why it's not working but data is.

Thanks in advance.

Can't dial or send/receive SMS

Hi there. Recently my Nexus 5X has something wrong with its communication function.
I am using CM13 nightly builds with ElementalX kernel with 4GLTE network. And everything works fine except:
When making calls, it ends up with "Network not available". However, the signal bar is full. Also, it is unable to send or receive any text message.

I have already tried:
1. Flash the latest factory image from Google(mtc19v). And it worked for a while then the issue recurred.
2. Dial *#*#4636#*#* and switch to "CDMA only" but it failed to make it, automatically rolled back to LTE mode.
3. Tried CM13 snapshot and other nightly builds, and still got the problem.

Does anyone have any advice? Thanks.
