Locking your SIM means a PIN will be needed each time you restart or if it’s placed in another device.
You can lock your SIM in your device’s settings menu:
Android
- In the settings menu, select the More tab and choose Security
- Select Set up SIM card lock
- Select Lock SIM card
- Finally, enter your chosen PIN
- Your SIM will now be locked
iPhone
- In the settings menu, select Phone
- Select SIM PIN
- Press the switch to activate your SIM PIN
- Finally, enter your chosen PIN
- Your SIM will now be locked
Please note: the default PIN on all Vodafone SIM cards is 0000.
