What is 4G calling or VoLTE? How do I get it?

4G calling (Voice over LTE, or VoLTE) carries your calls over the 4G network rather than old 3G. Calls connect faster and sound clearer, and you can use data during a call.

There’s nothing to switch on with us. It works automatically on any compatible phone. Now that 3G has gone, it’s also the only way calls work on our network.
