I am tearing my hair out. I have set this phone up from an icloud backup of my old iphone x BUT it won’t connect to the o2 cellular network. The SIM works fine in my old phone and when i recently upgraded it I ticked the 5G ready box.
When I go to settings/general/about/network I get a message saying ‘not available’ and when I click on this it says ‘phone not allowed’
Has anyone else had this problem and know how to resolve it. All help gratefully received.
