Common causes
- Repeated incorrect SIM PIN attempts
What to try first
- Stop entering codes
- Sign in to the carrier's official account or contact support
- Replace the SIM if the carrier says it is permanently blocked
What not to do
- Never guess a PUK
- Never use a code sold by an unrelated website
Stop if the phone is unsafe
Disconnect power and stop using a swollen, smoking, leaking, physically damaged or extremely hot phone. Contact the manufacturer or a qualified repair provider.
When support may be needed
Contact the carrier for account, SIM/eSIM, PUK, coverage or network-lock issues. Contact the manufacturer or qualified repair provider when the warning follows impact, liquid, unsafe heat or persistent built-in hardware failures.
