If you enter the wrong PIN to unlock your phone too many times, you might block your SIM. If this happens, you’ll be asked to enter an 8-digit PUK code to unblock it.
To get your PUK code, please can get in touch with our agents via Live Chat. Our Live Chat team are available 9am - 8pm Monday to Friday, and 9am - 6pm Saturday, Sunday, and bank holidays.
