Xiaomi How to Set up SIM PIN

Every SIM card comes with a PIN lock as standard to prevent unauthorized access, so when we start the Xiaomi smartphone, we are first asked for the PIN and then for the unlock pattern or code. If this is too much code entry, you can deactivate the SIM PIN lock if you wish.

Note: If the SIM lock is deactivated, the SIM card is unprotected, which means that if you put the SIM into another smartphone, you have immediate access to all SIM applications and services.

By default, the SIM card comes with a pre-defined PIN. It's rare that you can remember it well, so it's useful to be able to change it on your Xiaomi smartphone.

Note: If the PIN has been entered incorrectly three times in a row, we need the eight-digit SIM-PUK to unlock the SIM card, which we can find in the SIM card documentation next to the PIN.
