Title gets most out the way. For context I have an iPhone 16 Pro Max, which I got a few weeks ago. This is from transferring a number from GiffGaff.

I’ve done every method to try and receive texts and calls. It was working a few days ago. But then suddenly iMessage wouldn’t sign in properly. Now I’m locked out of my main Apple account and I am using a backup, I will have to perform a recovery. 

I’ve replace the sim, I’ve toyed around with every setting in my phone. My number will not verify, and didn’t before the reset of my phone. I’ve reset the Network settings numerous times. I’ve put the sim in an Android phone, so it isn’t the iPhone causing this. And I can only receive texts and calls off people on the iD Network too. I have no content restrictions on my account.

The agent on the helpline couldn’t phone due to working off a landline number. So I’m in the dark here. I have a ticket running with the service desk. But have been told to wait 2 days, twice now.

I was wondering if anyone had a solution to this problem, something that I’m missing as it would be very much appreciated. I mistakenly reset my phone thinking it would solve the issue but locked me out of my account (which I take fault for) but I haven’t been receiving important texts from my job, or friends and family or potential offers for jobs and university. Any help would be greatly appreciated!
