1. Turn on your phone
Press and hold On/Off until your phone is turned on.
2. Enter your PIN
If you're asked to key in your PIN, do so.
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.
