How to see the phone number on the SIM card in a Xiaomi Redmi smartphone: all methods

Have you just bought a new one Xiaomi Redmi or inserted an additional SIM card, but don’t remember its number? Or do you urgently need to provide your contact information, but don’t have a SIM card package at hand? The situation is familiar to many. Fortunately, on smartphones Redmi (and other devices on Android) there are several ways to find out your phone number - from standard settings to hidden USSD commands. In this article we will analyze all the working methods, including nuances for Redmi Note 12/13, Redmi A2 and other popular models.

It is important to understand that not all methods are universal. For example, on some operator tariffs (especially virtual ones, like Tele2 or Yota) USSD requests may not show the number. And in older versions MIUI (before 12.5) the settings menu looked different. We took these features into account and collected current instructions for Android 10–14.

If you use Redmi with two SIM cards, please note: some methods show the number only for the active SIM card. How to check both - read in the appropriate section.

1. Standard method: through the phone settings

The most reliable and universal method is to look at the number in the settings menu MIUI. It works on all models Redmi, including Redmi 10C, Redmi Note 11 Pro and new Redmi 13R. Instructions:

1. Open the application Settings (gear icon on the main screen).
2. Scroll down and select About the phone (or Information about the phone in old versions MIUI).
3. Tap on the item SIM card status (in some firmware - Information about SIM).
4. In the window that opens, you will see sections SIM 1 and SIM 2 (if you have two SIM cards). Under the operator's name there will be a line My phone number.

⚠️ Attention: On some tariffs (for example, corporate or M2M), the number may be displayed. how Unknown. This is not a phone error - the operator simply does not transmit this information.

If you have Redmi s MIUI 14 and above, the path may be a little differ:

Settings → SIM cards and mobile networks → [Select SIM] → My phone number

Check if the SIM card is active (there is no "No network" message)

2. USSD codes for quick number verification

USSD commands are short codes that are sent to the operator to receive information or manage services. To find out the phone number on Redmi, just enter one of the commands. application Phone:

• 📱 For all operators: #100# or #62# (shows the number and active forwarding services).
• 🏢 MTS: *111*0887# or *111# → "My number."
• 🟢 Beeline: *110*10# or *110# → "Find out the number."
• 🔴 MegaFon: *105# or *205#.
• 🔵 Tele2: *107# or *202#.

After entering the code, press the call button (green handset). After a few seconds, a pop-up window with your number will appear on the screen. If you see an error message instead of a number, this may mean:

• 🚫 The SIM card is not activated (for example, just purchased).
• 🔄 The operator temporarily does not support USSD requests (rarely, but it happens during technical work).
• 📵 You are in an area without coverage network.

On Redmi with two SIM cards, before dialing the USSD code, the system will ask which SIM card to use. Select the one you need and wait for the response.

3. Viewing a number through the Contacts application

In MIUI there is a hidden function that automatically saves your number in contacts under the name I or My number. To find it:

1. Open the application Contact (icon with a silhouette of a person).
2. At the top of the screen, tap on the tab I or My profile (depending on the version MIUI).

⚠️ Attention: This method only works if you previously entered a number when setting up your phone or synchronized contacts with Google. On a “pure” Redmi without linking to accounts, the section will be empty.

4. Using third-party applications

If standard methods do not work, you can install a specialized application to view information about the SIM card. We tested several options and chose the most reliable:

Application	Functions	Pros	Cons
SIM Card Info	Shows number, IMSI, operator, country	No extra water, works offline	Interface in English
My SIM Info	Number, SIM type, 5G support	Russian language, minimalistic design	Advertising in the free version
Network Signal Info	Number, signal strength, network type	Detailed technical information	Difficult for beginners

To use any of these applications:

1. Download it from Google Play (it is better to look for links directly in the market to avoid fakes).
2. Open the application and provide access to information about the phone (permission Read SIM card data).
3. The number will be displayed on the main screen or in the section SIM Info.

Important: some applications require root access to display full information. On non-rooted Redmi they will work in limited mode.

5. How to find the number of the second SIM card on Redmi

If your Redmi supports two SIM cards (for example, Redmi Note 12 Pro+ 5G or Redmi 11 Prime), standard methods can show the number only for the main SIM card. To check the second:

• 🔄 Switch the active SIM: Before using the USSD code or checking in the settings, select the second SIM card as the main one in Settings → SIM cards and mobile networks → Select SIM for calls.
• 📞 Call another SIM card: C call the first number (or from another phone) to the second SIM. The number will be displayed on the incoming call screen.
• 📩 Send an SMS: Write a message to any number (for example, your second) - the sender's number will be displayed at the top of the screen.

On some firmware MIUI there is a bug: when switching the active SIM in the settings, the number may not be updated. In this case, only rebooting the phone or using the USSD code for each SIM card separately will help.

What to do if the second SIM is not detected

Make sure that the SIM card is correctly inserted into the tray (with the chip facing up, the beveled corner matches the mark on the phone).

Check whether it supports your Redmi model works with two SIMs (for example, Redmi 9A was produced in versions with 1 and 2 SIM cards).

If the SIM is new, it may need to be activated through the operator (for example, Tele2 needs a code from SMS for this).

6. Alternative methods (if all else fails)

In rare cases, none of the listed methods work. This may be due to:

• 🛠️ Unofficial firmware (custom ROM) without support for operator functions.
• 🔒 Limitations of a corporate SIM card (for example, for business phones).
• 📡 Problems with the network (for example, in roaming).

In such situations, try:

• 📄 View the packaging from the SIM: The number is usually indicated on the plastic holder to which the SIM card was attached.
• 💳 Receipt from the communication store: When purchasing a SIM card, the number is indicated in the receipt or contract.
• 🌐 Operator's personal account: Go to your operator's website or application (for example My MTS, MegaFon Personal account). The number will be displayed on the main page.
• 📞 Call the operator: Dial your operator's support number (usually short, like 0890 for MTS or 0611 for Beeline) and ask for your number.

⚠️ Attention: If you use eSIM on Redmi (available on models with Android 12+, for example Redmi K50), the number can only be found through the settings or operator application. USSD codes for eSIM often do not work.

7. Common mistakes and how to avoid them

When trying to find out the number on Redmi users often encounter typical problems. We have collected the most common ones and ways to solve them:

Problem	Cause	Solution
The number is not displayed in the settings	The operator does not transmit data or the SIM does not activated	Use the USSD code or contact your operator
USSD code does not work	There is no network or the operator is blocking requests	Check network coverage or restart the phone
The application does not show number	No permissions or SIM is not recognized	Grant access to SIM and reinstall the application
The number is not displayed in full (for example, +7***)	Operator restriction for security	Check the number in your personal account or with the operator

Another common mistake is confusion between data-i="215">and phone number And IMSI (unique SIM card identifier). IMSI looks like a long string of numbers (for example 250991234567890) and is not suitable for calls. If you see such a code instead of a number, it means that the operator does not transmit information about the number to the phone.

FAQ: Answers to frequently asked questions

Is it possible to find out the SIM card number without a phone?

Yes, but for this you need access to the SIM card packaging, a receipt from a phone store or your personal account operator on the computer. The SIM card itself cannot be read without a phone - for this you need a reader (for example, in the ATMs of some banks).

Why is there no "My phone number" section in the settings on Redmi with MIUI 14?

In the latest versions MIUI the path to the number has changed. Try: Settings → SIM cards and mobile networks → [Select SIM] → Advanced → My number. If there is no section, use the USSD code.

Can the SIM card number change over time?

No, the phone number is assigned to the SIM card upon activation and does not change even if you change tariff or operator (while keeping the same SIM card). The exception is if you specifically ordered a number change from the operator.

How to find the SIM card number on Redmi if the phone is locked?

If the screen is locked but the phone is on, try calling it from another device - the number will be displayed on the incoming call screen. If the phone is turned off, there are no alternatives (except for SIM packaging or a receipt).

Do these methods work on Redmi with custom firmware (for example, LineageOS)?

On unofficial firmware, standard paths (Settings → About phone) may not work. In this case, use USSD codes or applications like SIM Card Info. Please note that some functions (for example, displaying a number in contacts) depend on the version Android and firmware kernel.
