By default, a SIM card is delivered with a previously defined PIN. In the rarest of cases you can remember it well. Therefore, it is useful to be able to change this on the Huawei smartphone.

Note: If the PIN was entered incorrectly three times in succession, you need the eight-digit SIM PUK to unlock the SIM card. We find this in the SIM card documents, next to the PIN.
