1. Turn on your phone
Press and hold Disconnect until your phone is turned on.
2. Enter your PIN
If you're asked to key in your PIN, do so and press OK.
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. The PUK can be obtained by contacting customer services. 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.
