Turning my mobile phone PIN on or off

If you want to protect your SIM against unauthorised use, you need to turn on your PIN protection. Once done, it needs to be keyed in when you turn on your mobile phone.
Please note: your PIN doesn't prevent others from accessing the contents of your mobile phone (such as pictures and messages). You can prevent this by turning on the phone lock code.
