A provider switch blocked my iPhone 15 Pro Max and now I have SOS
Liberty Mobile bought ATT where I live. I got a text where they said they would be switching my phone. Well, it seems they did and now I have no Cellular data (SOS) and I called them. They gave me a QR Code to enable it, but they say the phone is blocked. I've had the phone for about three weeks working perfectly. They said something about calling Apple, but what does Apple have to do with this? I am so upset. A new phone that one works with wifi, but I can't send or receive calls.
Thank you,
