I bought a SIM locked iPhone 17 Pro Max in Pakistan that is locked to AT&T. I want to know what happens if the AT&T installments are not paid.
Will the phone become unusable or “bricked”? Could it start showing the message: “This device can’t be activated. Please call this number to activate your device”?
I’m asking because many people with AT&T SIM locked iPhones have reported this issue, and when they check their devices on Sickw.com, the status shows “Blocked (Property of AT&T).”
