What is the make and model of your phone?
If you have an older phone. You will need VoLTE to make and receive calls due to the recent 3G shutdown.
Here is more information on VoLTE. Enter the IMEI of your phone to see if it is VoLTE compatible.

If not compatible then you need to look for a new phone.
