Hi, did you by any chance recently receive an SMS from EE telling you that some EE service settings had been updated, to delete the message and restart your phone?
My partner and I both had this happen to our iPhones recently. We both lost EE wifi calling and our ability to make and receive calls over EE 4G after our settings were updated. Even though we had two to three bars of EE 4G signal nine times out of ten we couldn’t make outgoing calls and inbound calls would go straight to voicemail.
In the end we spent an hour on the phone to EE support (first, second then third line engineering support) who confirmed there was no local cell issue but that we might have had some corrupt settings applied to our phones. They then applied what they called a ‘full account reset’ which was essentially them sending the service configuration SMS messages you get when you first join EE. We deleted the SMS messages, restarted the phones and everything kicked back into life, wifi calling reappeared and we could make and receive calls again. According to EE support this was an issue that related to some of the configuration updates they sent out for their new 5G services.
