To check whether your device is compatible, just click here. If your device is compatible and you’ve had no recent issues you should be all set. If you’re having issues with calls or texts, it might be a good idea to take a few more steps:
1. Check to see if there are any software updates for your phone that have not been installed. 2. Ensure that VoLTE is turned on. While the naming conventions may vary, the easiest way to see if VoLTE is enabled on your phone is to check within the device’s settings: Click on the Settings icon -> click ????-> type “volte” -> click VoLTE Calls Menu -> switch the VoLTE Call Toggle to “On.” If after typing “VoLTE” no menu option appears, the device either does not support VoLTE or VoLTE is defaulted to “On” which is likely if the phone is fairly new.
3. Confirm the APN settings for the device.
