How to completely remove phone numbers from SIM-Xiaomi maps: from standard methods to hidden features

Why are the rooms SIM-Xiaomi maps could be a problem

SIM cards in Xiaomi smartphones (including Redmi Note models) 12, POCO X5 mi 11) They still store contacts directly on a chip, despite the ubiquitous shift to cloud services, which creates a few specific problems. First, duplicate contacts, where the same number is displayed in both the phone's memory and the phone's memory. SIM-And the second thing is, there's a limited limit, most of the time. SIM no more 250-300 with the cut-off fields (only the name) + Finally, when you transfer the SIM to another device, all these numbers automatically pop up, clogging the new phone book.

Another trap is hidden contacts, and many users don't even know that their SIMs have numbers that were added years earlier through old button phones, which are not displayed in the main MIUI contact list, but take up space and may conflict with current data, such as when synchronized with Google Contacts or Mi Account.

In this article, we will discuss all working methods of cleaning. SIM-cards – from basic (through the standard menu) to advanced (using engineering codes and ADB). We will pay special attention to the nuances for different versions. MIUI (12–14) and models with hybrid slots (e.g. Redmi Note 10 Pro, where SIM2 It can work as a memory card).

Method 1: Delete via the standard Contacts menu

The most obvious method is to use the built-in Contacts app (an icon with a human silhouette). MIUI 14 Ways to Governance SIM-It's hidden deeper than in the previous versions:

1. Open the Contact App (not to be confused with Phone!).
2. Tap the three-point menu (⋮) top-right → Select Contact Management.
3. Scroll down to the Contact Block SIM-Cards (in some models it is called contact cards).
4. Select the desired SIM (if there are two) → tick the number to delete → click Remove (basket icon).

⚠️ Attention: B MIUI 13 and later, when attempting mass removal, the system may give an error "failed to delete contact" due to operator restrictions, the solution is to delete the numbers one by one or use method 3 (via the engineering menu).

Check the backup of contacts in Google Drive

Disable synchronization with Mi Account (Settings → Accounts)

If the standard method didn't work, don't be quick to blame the firmware. Often the problem is type. SIM-map:

• 🔹 Old ones. SIM (Until 2015, contact editing may be blocked due to outdated protocol.
• 🔹 eSIM (in Xiaomi 13 Pro and later) does not support the storage of contacts on the chip – all numbers are automatically stored in the memory of the phone.
• 🔹 Two-chip. SIM (Some operators require the choice of a “main” contact management slot.

Method 2: Cleaning through the “Settings” of the phone

An alternative way is through system settings, which is suitable if the Contact application is not working correctly or is not available (for example, after resetting to factory settings).

1. Go to Settings → Applications → Application Management.
2. Find Contacts (or Contacts and Calls) in the list → open Warehouse.
3. Tap SIM-card contact management (in some firmware, the item is called Import/Export).
4. Choose. SIM-map → mark the numbers → remove.

⚠️ Attention: On devices with MIUI for POCO (for example, POCO F4) This path may not be available. Instead, use the settings search (the magnifier icon at the top) and type in the query "SIM contact".

Method 3: Engineering menu (for power users)

If standard methods don't work, you can use a hidden engineering menu, which requires caution, because wrong actions can disrupt the network, and is suitable for Qualcomm Snapdragon models (most Redmi and POCO).

⚠️ Note: On devices with MediaTek processor (e.g. Redmi) 10C) engineering menu code other:

It is the way to manage contacts: Connectivity → SIM Toolkit → Contact Manager.

After cleaning through the engineering menu, it is recommended to restart the phone. SIM-The card may temporarily “disappear” from the network – this is treated by re-inserting the card or changing the network mode (Settings) → SIM-maps and mobile networks → Preferred type of network).

Method 4: Using Third-Party Applications

If the built-in MIUI tools fail, third-party utilities will come to the rescue.
