What if I enter the wrong PIN?

If you enter an incorrect SIM Card PIN or PIN2 three times in a row, your SIM Card will block. You will need a PUK (personal unblocking key) to unblock your SIM Card.

Call Business Customer Services on 07973 100 158 for details on how to unblock your phone.

Do not attempt to guess the PUK code.

If you enter your PUK code incorrectly 10 times in a row, you will permanently block your

SIM Card and you may have to return your phone to Orange.
