    SIM card protection

    Arrow left Xperia Z5 Premium Dual support overview

    You can lock and unlock each SIM card that you use in your device with a PIN (Personal Identification Number). When a SIM card is locked, the subscription linked to the card is protected against misuse, meaning that you have to enter a PIN every time you start your device.

    If you enter the PIN incorrectly too many times, your SIM card will get blocked. You then need to enter your PUK (Personal Unblocking Key) and a new PIN. Your PIN and PUK are supplied by your network operator.

    To set up or remove a SIM card lock

    1. From the Home screen, tap Icn sony home apptray normal.
    2. Find and tap Settings > Lock screen & security > Set up SIM card lock.
    3. Select a SIM card.
    4. Tap the Lock SIM card slider to enable or disable the SIM card lock.
    5. Enter the SIM card PIN and tap OK. The SIM card lock is now active and you will be prompted to enter the PIN every time you restart the device.
