Why turn it off? SIM-Xiaomi map and when it is needed

Shutdown SIM-cards on smartphones Xiaomi, Redmi or POCO It can be used in a variety of situations, from simple battery savings to network problems, for example, if you are traveling abroad and want to avoid roaming, or your number is temporarily blocked by the operator. Sometimes deactivating the SIM helps to eliminate errors like “No Network” or “Emergency Calls Only” that do not disappear after a reboot.

This is especially relevant for owners of dual-slot models (such as the Xiaomi 13 Pro, Redmi Note 12 or POCO X5), where one of the sims can conflict with the other. It is important to understand that simply removing a card does not always amount to software shutdown: in some cases, the phone continues to scan the network, using energy.

Key point: if you plan to completely remove the SIM from the system (for example, before selling your phone), one disconnect in the settings will not be enough – you will need to reset the mobile network settings.

The most obvious and safe method is to use built-in MIUI tools. It is suitable for all modern models, including Xiaomi 14, Redmi Note 13 Pro+ and older devices based on MIUI 12-14. the interface may differ slightly, but the logic remains the same.

To deactivate the SIM:

Open the Settings app (cog icon).
Go to section. SIM-maps and mobile networks (or mobile network on some firmware).
Select the SIM you want to disable (if there are two, they will be numbered: SIM 1 and SIM 2).
Move the slider opposite the item Include SIM-map off..

What happens after that?

📵 Simka will no longer be determined in the network, but will remain in the slot.
🔋 Battery consumption will decrease (especially if the main sim is disabled).

If the SIM continues to be determined after you turn off (e.g., in Settings → About Phone → SIM Status), try rebooting the device. In rare cases, resetting mobile network settings helps, read about this in the section on resets.

Method 2: Use of the USSD-deactivation

USSD-Teams are a universal tool for direct control of the SIM directly through the operator. They work independently of the firmware. MIUI, But it requires that the card be active at the time you enter the code:

🔄 You must temporarily suspend services (for example, before traveling).
🚫 The operator blocks access to the phone settings (rarely, but sometimes).
📡 Simka is in conflict with another and needs to be “nullified” at the network level.

Here are the main commands for popular operators:

Operator.	Code for deactivation	Action.
MTS	111081#	Suspension of services (for 30 days)
Beeline	11008#	Blocking outgoing calls
Megaphone	10508#	Roaming off
Tele2.	2201#	Blocking all services

Importantly, these codes don't turn off the phone-level SIM, they interact with the operator. For example, if you type *111*081# into the MTS, your number will remain on the phone but will stop working on the network. To fully deactivate the card, combine this with the first one.

Method 3: Physical extraction SIM-cards (pros and cons)

The most radical method is simply to take the SIM out of the slot, which is guaranteed to turn it off, but has its nuances. For example, on some Xiaomi models (especially hybrid slots like the Redmi 10 or POCO M4 Pro), when you remove one SIM, the second one can automatically activate if it is installed.

Step-by-step:

Turn off the phone (required! Removing the SIM on the device on could damage the slot).
Find a tray for SIM-maps — usually on the top or side of the maps — on newer models (e.g. Xiaomi) 13T) The tray may be hidden under the lid.
Use a paper clip or a special key (comes with a set) to open the tray.
Carefully remove the SIM without touching the contacts. If the card is inserted into the adapter (for example, nanoSIM in microSIM), delete it along with the adapter.

Advantages of the method:

⚡ Instant result - the SIM completely shuts down.
🔒 Eliminates random activation (unlike software disabling).
🛠️ Suitable for devices with damaged software where settings do not work.

Disadvantages:

⚠️ Risk of damaging the slot with careless extraction.
🔄 When re-installing the SIM, a reboot may be required.
📵 If the phone was tied to a SIM (for example, for Mi Account), some features may stop working.

What if the tray is jammed?

If the tray is for SIM-The card is not pushed out by a paper clip, do not make excessive efforts! Try: 1. Heat the case with a hair dryer (temperature not higher than 50).°C) – sometimes helps when moisture is ingested. 2. Use a thicker object (for example, an unbended stationery brace). 3. Contact a service center – self-attempts can break the mechanism.

If you have retrieved the SIM, but the phone still shows it in the settings ("No Network Status"), reset your mobile network settings (section 5 of this article).

⚠️ Note: Not all developer mode options are available on customized firmware (e.g. Xiaomi.EU). Incorrect settings can lead to network loss or communication module failure. If unsure, use standard methods (sections 1-3).

Method 5: Reset mobile network settings (if the SIM does not turn off)

If the SIM is still active despite all attempts to deactivate it, the problem may be in the network settings that have gone wrong, which often happens after the MIUI update or the card is retrieved incorrectly, in which case the reset of the mobile settings helps.

How to perform the reset:

Open the Settings. → SIM-maps and mobile networks.
