My girlfriend was having trouble activating her new SIM. The sim would not work in her iPhone 11. I put the SIM into my phone to help set up (I am also with ID mobile). This seemed to allow me to activate her SIM using her details and phone number. I then removed the SIM. She put the SIM in her phone which then seemed to be working. My SIM now is not working in my phone. My GF now has signal but she has my phone number. Not hers
We checked to ensure we had not accidentally swapped SIM cards but this is not the case. Her SIM matches the code that came in the post with the SIM card.
Been trying to go on the chat for about 2 hours and keep getting kicked off. Any help would be appreciated
