Wifi calling on Samsung J2

[Dero1]

I have an existing J2 working on wifi calling and have just updated a samsung ace to another J2 using the existing sim from the old phone but when the wifi calling is activated on the new j2 it does not work. When I swap existing sim from the working phone to the new phone  wifi calling calling works fine. Does the old sim need to be "updated" or replaced to enable wifi calling?

Hi Dero1, wifi calling requires VoLTE (voice over the 4g network) to be active from an account level, I would check with the team on 125 111 to make sure this is active.
