You can protect your SIM card by setting the phone to ask for your
PIN code every time the phone is switched on. To do this, you need

The PIN code is usually supplied with the SIM card. If not, contact
your service provider. You can change your PIN code in the Change

succession, the SIM card is blocked and you need to enter the
PUK code to unblock the SIM card. See “Access codes”.
