I've been having problems with my sim card for a couple of weeks, my phone (XS Max) kept suddenly not recognising it altogether. Last week I was walked through a number of checks and it was decided to send me a new, replacement SIM out. This finally arrived this morning, and I went through the sim swap process. Followed instructions, waited til old SIM lost service, replaced with new SIM, turned phone off and back on.
Now, however, I have text service, I have 4G internet service...but no phone service. At first I could receive calls (though they all came through as unknown numbers) - but now I can neither receive nor make calls. Can't even call O2 as any attempt to ring out drops instantly.
Is it just a case of waiting a full 24 hours to see if phone service returns, give them chance to swap properly?
