If you enter an incorrect SIM PIN three times, your phone will lock. You’ll need to enter a Phone Unlocking Key (PUK) to unlock it.
To get a PUK, you’ll need to contact us by calling 191 (free from any Vodafone mobile) or 03333 040 191 from any other phone (standard call charges apply), or through Live Chat.
Once you’ve got your PUK, follow the on-screen directions to enter it and unlock your phone.
Please note: You will have several attempts to enter the correct PUK code (this may vary by device, but remaining attempts will be shown). If the wrong PUK is entered too many times in a row, your SIM will be blocked permanently.
