iPhone IMEI blacklisted
I bought a Grade A iPhone 17 Pro Max from CEX in November 2025.
I’ve been travelling abroad since January and have been using a Vietnamese SIM and various eSIMs without any issues. I returned to the UK today, but when I inserted my UK SIM, it wouldn’t work. I also tried two different eSIMs, and neither worked.
I ran a CheckMEND report, which says: “Currently Blocked: The device has been reported lost or stolen to a phone network and will not function on some networks.”
I have no idea when the phone was blocked because it has worked perfectly throughout Asia. Today was the first time I discovered there was an issue. I also contacted my UK network provider, and they confirmed they were not the ones who placed the block.
If I take the phone back to CEX with my receipt, is this something they would refund or replace under their warranty? The phone was Grade A when I bought it, but I have since dropped it and it now has some scuffs around the sides. Would the cosmetic damage affect my claim?
