What's 4G calling?
4G calling, also known as VoLTE or Voice over LTE, lets you make and receive calls over the 4G network.
It’s just like making a normal call, but instead of using 2G/3G signal it uses 4G. So, calls will connect quicker and voice and video calls will be clearer.
How it works
Both you and the phone you’re calling need:
- A 4G calling compatible phone
- To be in a 4G network area
- To have 4G calling switched on
You’ll see a symbol something like this when 4G calling is available.
Then, just dial the number you want to call like normal.
And if you’re using Wi-Fi calling and you move to a 4G area, your calls will transfer without disconnecting.
When 4G coverage isn't available
Calls will connect using 2G/3G signal like normal or you might be able to use Wi-Fi calling (if your phone’s compatible).
