The PIN protects your SIM from unauthorised use. If use of PIN is turned on, it needs to be keyed in when you turn on your phone. Follow these instructions to turn use of PIN on or off.
1. Find " SIM lock"
2. Turn use of PIN on or off
Depending on the current setting, the PIN is turned on or off.
If the wrong PUK is entered ten times in a row, your SIM will be blocked permanently. In this case, you need a new SIM from Vodafone.
