I want to insert the SIM card into an alarm system. What should I do if I'm asked for the PIN?

The SIM card comes with the PIN already unlocked, so there is no need to unlock it. The PIN is provided on the plastic holder of the SIM card, and if needed, you can disable it by inserting the SIM card into a smartphone or following the instructions in the device's user manual.
