Did you get a solution to this?
Maybe your device is a Kate. Try to flash this >> https://www.androidfilehost.com/?fid=24713784966774787 << and see if you will get your SIM back.
try flashing the nexus radios..search on the forum you will find them

Does your sim card support 4g? If it's too old, there is a chance it doesn't

Yes, it does. Recently I ported my old SIM card in new Airtel 4g.

4G not working

i have currently flashed Evolution X 5.2 on my phone and 4G is not working for me. I have Vodafone 4G sim inserted in my device. i had tried to change APN's and even after flashing stock fastboot ROM 4G is not working for me.
it a device related issue.
Twice 4G was working but after a reboot 4G is disabled again and 2G is only working.
Also the same 4G sim is working on my other devices.
Please Help
Thanks in advance
(edit: even after flashing evolution x 5.3 this issue persists)
