If an incorrect PIN is entered three times in a row, your SIM will be blocked. To unblock your SIM, you'll need to key in your PUK. You can get the PUK by calling customer services on 191 from a Vodafone mobile phone. If you're using a land line, you need to dial 03333 040 191. Please note: If you key in the wrong PUK ten times in a row, your SIM will be blocked permanently. In this case, you need a new SIM from Vodafone.
