4G Calling just means your device can make calls and send texts over 4G. It’s also known as “Voice over LTE” or VoLTE. It offers crystal-clear calls over the 4G network with quick setups.
Important points to keep in mind:
With 3G being phased out, a 4G-VoLTE device ensures uninterrupted calls and excellent service once 3G is gone.
You should start to consider upgrading to a VoLTE-compatible device to be ready.
You don't need to do anything to use 4G calling - apart from having an enabled device!
