eSIM not working
I've installed my SMARTY eSIM using the QR code and confirmation code. My Three service has now been disconnected, but I have no SMARTY service. When I try to transfer the number on my iPhone I get Error Code 300 saying the network is undergoing maintenance and can't support transfers. Any idea? Currently don’t have a phone 😭 I had an email to say everything had been completed
