How to completely disconnect SIM-Xiaomi map: all ways (including hidden ones)

Shutdown SIM-Cards on Xiaomi, Redmi or Poco smartphones can be needed in a variety of situations: from saving battery power to temporarily switching to another operator. However, many users are faced with the fact that standard deactivation methods do not always work as expected – especially on dual-device devices. SIM-In this article, we will discuss all possible ways, including little-known tricks through the engineering menu and the design of the device. USSD-Teams that are not described in official documentation.

It's important to understand that simply removing a card doesn't always amount to software shutting it down. For example, on some Xiaomi 12T or Redmi Note 11 models, even after the SIM is physically removed, the system can continue to scan the networks, consuming charge. And in the case of eSIM, the deactivation process requires a separate approach. We tested all methods on current versions of MIUI 14 and 15, so the instructions will work on new devices in 2026.
