It's probably the issue with SIM, check with your network provider. Also, check whether your device is updated with latest firmware version.
but when i put the sim in another phone its working volte
Reset your phone and problem will be solved. I have already faced this issue with Airtel 4g sim.
Hi, we'd request you follow the below steps:
1. Check your phone for latest software version.
2. Clear system cache.
3. Try the same under safe mode:
Hold the power button for 5 seconds => When the screen flashes with option => Press & hold power option => You will get an option to restart in safe mode
4. If still you face the issue factory reset your phone after taking a full backup: https://www.asus.com/support/FAQ/1006346/
Thats airtel problem... Those assholes advertise on tv saying network reaches everywhere. I would start recharging airtel sim if network breaches through my roof.
