4G calling on Xperia xz2 compact?

[Jtscotland]

Does the Xperia xz2 compact have volte/4G calling capability?

if so, how do I find it?

You'd need to have bought the device from an Operator's stock, as they add their own software to support this option, it's not a default option.

If that's your case, take a look here, for steps of where it should be in settings.
