I have a Samsung Galaxy Z Flip 3 with the VoLTE option enabled. Do i need to do anything to enable it on Smarty's website or app for my account? The phone is apparently on Smarty's supported list for VoLTE.
I have now restarted the phone and checked Call Forwarding is set to None. The Voicemail that the caller hears is from their network not Smarty. Incoming texts are also failing.
