You’ll see this message if your PIN has been locked, and you’ve tried unsuccessfully to unlock it using a Phone Unlocking Key (PUK).
A PUK is specific to the SIM card it was issued against. If you enter it incorrectly 10 times, your SIM card will be permanently blocked and will need to be replaced.
You can get a replacement SIM by using the Live Chat button below, calling us, or by visiting your nearest Vodafone store
Once you’ve got your replacement SIM, you’ll need to activate it using our online SIM Swap tool
