Forgotten. PIN-code SIM-Are you tired of entering it every time you turn on Xiaomi? Unlocking the SIM on the brand’s smartphones has its nuances – especially when it comes to firmware MIUI 12-14 with their unique interface, and in this article we will discuss all the current methods: from standard disconnection through settings to bypassing locking if the password is lost. It is important to understand that the procedure is different from similar actions on smartphones of other brands – here both the shell version and the device model play a role (for example, the Redmi Note 12 or the Redmi Note).

• 🔄 Firmware updates: After major updates (for example, with MIUI 13 on MIUI 14) settings SIM may be dropped.

This is due to the increased protection of flagship models. If your smartphone is in the POCO F or Black Shark line, chances are you will need an alternative method from the following sections.

Method 1: Standard PIN disabling via MIUI settings
