If you enter your SIM PIN incorrectly three times, your SIM will be locked, and you'll need a PUK (PIN Unlock Key) to unblock it.
How do I get a PUK code to unblock my SIM or eSIM?
You can easily get your PUK by chatting with one of our Live Chat agents. Take your time entering the PUK - if you enter it wrong 10 times, your SIM will be permanently locked, and you'll need to grab a new one.
