@Gary74 Can't say for sure if this will help you, but I found this: https://www.wiknix.com/how-to-fix-not-registered-on-network-in-samsung-or-android-phones/

Adding to the advice by @Bambino and checking on the Samsung forum, a simple change of sim fixed the issue @Gary74

I think the IMS is required for WiFi calling so shouldn't effect anything else.

Removing and reinserting the SIM might fix it if it's a bit of static on the card.
