Why Xiaomi doesn’t keep a contact with you SIM-map: full analysis of the problem

You are trying to keep an important number on SIM-Map of Xiaomi, Redmi or POCO, But the phone is stubbornly ignoring the command, and this problem is familiar to many device owners. MIUI — from budget Redmi 9A In 80% of cases, the fault of the software, but sometimes the root of the evil lies deeper - in the settings of the operator or even physical damage to the slot.

In this article, we’ll look at all the possible reasons why contacts aren’t saved on SIM, from the banal lack of space to hidden firmware bugs, and you’ll get unique MIUI 14/15 solutions that you won’t find in standard instructions, including workarounds for hybrid slot models (like the Redmi Note 12 Pro+), and at the end, an FAQ that answers the most common user questions.

Verification of baseline conditions: SIM-slot

Before digging into your phone’s settings, make sure the issue isn’t on the side. SIM-A card or a physical slot:

• 🔍 Type SIM-maps: Modern nano-SIM (especially from MTS, Beeline, Television)2) They often have limited memory, all of them. 250-500 Please specify the limit with the operator through USSD-team *111# or in a private office.
• 📱 Hybrid slot: On Redmi Note models 11/12 and POCO X5 The second slot is paired with a microSD connector, SIM automatically switches to “calling only mode” by blocking contact recording.
• 🔧 Physical damage: Oxidation of slot contacts or microcracks on SIM Check the card under the magnifying glass, if you see any scratches on the chip, it's time to replace it.

The problem is that MIUI doesn't show any errors in SIM problems -- it just silently ignores the save command to diagnose a hardware malfunction.

⚠️ Warning: If the phone stops seeing after restarting SIM In general, even for calls, the problem is exactly in the slot or the card. Don't try to clean contacts with alcohol - in 60% of cases, this aggravates corrosion.

2. MIUI settings: where to look for a lock?

MIUI is known for being a caring user, sometimes too caring, and some regional versions (especially in India and China) have the default SIM option disabled due to local data protection laws.

Open Settings → Applications → Contacts → Permissions and make sure that:

• 📞 The "Contact Storage" permission is included.
• 🔒 No restrictions for "Changing system settings" (need to record on the SIM).
• 🌍 Regional settings are not set to “China” or “India” (check in Settings) → Additionally. → Region).

If the permissions are fine but the problem remains, try resetting the Contacts app settings:

1. Go to Settings → Applications → Application Management → Contacts.
2. Click on "Storage" → "Clear Data" (this will only delete the cache, the contacts in the phone will remain).
3. Reset the device.

💡

On some firmware (e.g. MIUI 13 for Redmi Note 10 Pro), the SIM save option only appears after the first successful import of SIM contacts into the phone. Try importing 1-2 contacts from the card first, then exporting them back.

3. Firmware bugs: how to get around the limitations of MIUI

Since 2022, MIUI 13/14/15 has been featured: the system blocks the recording on SIM if the contact contains non-Latin characters (Cyrillic, hieroglyphs, emoji), this applies even to Russian firmware!

Decisions:

• 🔤 Transliteration: Replace the Cyrillic alphabet with the Latin alphabet (for example, "Ivanov" → "Ivanov”): Online services may be used for this purpose.
• 📱 Third-party apps: Install True Phone or Contacts+ Google Play – They Bypass the Restrictions MIUI.
• 🔧 Firmware rollback: If the problem has occurred after the update (for example, with the MIUI 12.5 on 13), try to roll back through Settings → The phone. → Update MIUI → Three points. → Select a Service Package.

For advanced users, there is a radical method – editing a telephony.db file through ADB. This is risky, but it works in 95% of cases:

adb shell


su




sqlite3 /data/data/com.android.providers.contacts/databases/contacts2.db




UPDATE raw_contacts SET account_name='SIM' WHERE account_name='Phone';

⚠️ Attention: Wrong commands ADB You can lose all contacts. Before experimenting, back up through Settings. → Google → Backup.

Installed drivers Xiaomi on PC

USB Debugging enabled (Settings → About Phone → MIUI Version → 7 times tap)

Backup of contacts in Google Account

Original connected USB-cable (not all cables support data transmission)

4.Problems with the operator: hidden limitations

Russian operators (MTS, Beeline, MegaFon, Tele2) often impose restrictions on recording contacts on SIM to encourage the use of cloud services, for example, Beeline blocks this feature for unlimited calls, and Tele2 for SIMs released after 2021.

How to check:

1. Insert SIM into another phone (such as a Samsung or iPhone) If contacts are saved, your Xiaomi is a problem.
2. Call the operator (USSD-commands: *111# for MTS, *105# for Beeline) and check whether your support is SIM contact-record.
3. Try to keep in touch through USSD-Operator menu (for example *123*number# for Megaphone).

If the operator has confirmed the lock, there are three options:

• 🔄 Replace SIM It can also be used (sometimes even in the same way).
• 📱 Use cloud storage (Google Contacts or Mi Cloud).
• 💳 Buy SIM Another operator (e.g. Yota or Tinkoff Mobile does not normally block the recording).

5. Hardware malfunctions: when it is time to go to the service

If all software methods have been tried and contacts are still not saved, the problem may be:

• 🔌 Faulty. SIM-slot: A frequent problem with Redmi 9T and POCO M3 — oxidation of contacts due to moisture.Symptoms: the phone periodically loses the network, SIM "disappearing after heating.
• 📶 Damaged communication module: After falls or impacts, the antenna plume may move away, which leads to recording failures on the SIM.
• 🔋 Slot power instability: On some Xiaomi (e.g. Mi 11 Lite) the slot is connected via a separate controller, which degrades over time.

Self-diagnosis:

1. Try inserting the SIM into another slot (if there are two).
2. Check if the contacts are saved to another SIM (borrow from a friend).
3. Run the hardware test through the engineering menu: dial ##4636## → Phone Information → scroll down to the SIM Status block.

If you see errors such as SIM ERROR: 6 or ICCID NOT AVAILABLE in the engineering menu, this is a direct signal of a malfunction of the slot or SIM.

⚠️ Note: If the phone is warranty, do not open it yourself! in Xiaomi, the warranty is removed even when you replace it SIM-Only contact authorized centers (list on the official website).

6. Alternative ways to maintain contacts

If you can’t solve the problem with SIM, here are 5 reliable alternatives:

• ☁️ Google Contacts: Automatically synced, available on any device. Included in Settings → Accounts. → Google → Synchronization of contacts.
• 📱 Mi Cloud: Cloud from Xiaomi (15GB free). Setup: Settings → The phone. → Mi Account. → Mi Cloud → Contacts.
• 💾 Export to file VCF: Open Contacts. → Three points. → Contact management → Imports/Exports → Export to storage. The file can be copied to a PC or other SIM third-party.
• 📧 Email: Select your contacts → Share. → You can send up to 100 contacts to your email at a time.
• 🔗 Third-party apps: Simpler Contacts or My Contacts Backup can save contacts to the cloud or memory card.

For users who change frequently SIM-maps (for example, on trips), the best option is to duplicate contacts:

1. Save the main numbers in Google Contacts.
2. The most important (relatives, work) duplicate on SIM via another phone.
3. Make a backup in.vcf format to the memory card.

💡

If you travel frequently, use Xiaomi’s dual-sim phones (like the Redmi Note 12 Pro+ or POCO F5). Set up the main contacts on the first SIM and use the second for local carriers.

7. Frequent user errors

The experience of the service centers shows that 30% Problems with maintaining contacts on SIM It's caused by some basic errors.-5 among:

• 📵 No network: No connection to the operator (even without the Internet!) MIUI block SIM. Check the signal level in the status bar.
• 🔒 Hablocked PIN-code: If you entered PIN wrongly 3 times, SIM lock-in PUK. In this state, recording contacts is not possible.
• 📱 Flight/Energy Saving Mode: In these modes, access to SIM Turn them off in the notification curtain.
• 🔄 Wrong order of action: First you need to open the contact for editing, then select "Save on" SIM", not.
• 📵 SIM not activated: New SIM require activation through USSD or call (for example, Tele2 needs to dial 111).

Another common mistake is trying to keep in touch with an empty name. MIUI blocks such records, but does not show an error. Always fill in the name field (you can put a dot or dash).
