What error are you getting on your iPhone 15 when you try to use it? With the QR did it show you any error message? Please send me a PM with the contact number so I can investigate.
Hi there rterblanche, I am really sorry to hear that you have been struggling on that side. Please forward me the contact number that you signed up with via PM so I can be able to investigate and advise.
That can also be a fact that can affect your network and also if the tower might be faulty. But you can forward us your contact number linked to your AirMobile via PM so I can investigate for you.
