What phone do you have? Is it compatible with VoLTE? You can check by entering your IMEI number here.

Did you recently join Public Mobile? If yes, did you remove the previous sim from from phone and enabled the Public Mobile sim? 

What type of phone do you have? When you are able to call what is the status of your phone in the top right corner? LTE, 3G?
