How to check which one SIM-The card called Xiaomi: all working methods

You missed an important call, but you're not sure which of the two. SIM-On Xiaomi's dual-slot smartphones, this problem occurs often - especially if you use both SIMs actively. Unlike some brands, where the caller's number is displayed with the slot (for example, the slot is displayed, "SIM1: +7...), interface MIUI It doesn't always give a definitive answer. In this article, we'll look at 5 proven ways to determine exactly which one you want to use. SIM-The card was called – from standard call log features to hidden system logs.

It is important to understand that the methods differ depending on the version of MIUI (12 to 15), the model of the smartphone (Redmi Note 12, Poco X5, Xiaomi 13, etc.) and even the carrier. For example, on some firmware, the caller’s number is illuminated with a color corresponding to the SIM slot, and on others, you need to analyze technical logs. We will consider options for all cases, including situations where a call was missed or reset.

If you're looking for the answer to the question "can you know this after you restart your phone" or "how to tell the difference between incoming and outgoing," you'll find the detailed instructions below, with explanations. For convenience, we've divided the methods by difficulty level: from basic (suitable for beginners) to advanced (for users willing to work with system files).

1. Standard Call Log: Where to Look for Tips

Let's start with the obvious, the built-in phone app. MIUI There are visual markers here that help distinguish SIM-Maps, but they're easy to miss. Open a call log and pay attention to the following details:

• 🔴 Color marking: Incoming calls to SIM1 often displayed in green, on the SIM2 — Check the legend at the top of the screen, which may have the captions "Map 1" and "Map 2".
• 📌 Operator icons: The logo of the mobile operator (for example, MTS, Beeline) sometimes appears next to the number. SIM-maps, this is a direct pointer.
• ⚡ Fast filter: In the upper right corner of the magazine there is a filter button (three dots or funnel). SIM1" or "SIM2" — You will see calls on each card separately.

If your MIUI version doesn’t have these markers, don’t worry. For example, on the Xiaomi 12T Pro with MIUI 14, the color scheme may be different from the Redmi 10C with MIUI 13.

⚠️ Note: Some firmware for China (e.g., for example, MIUI China ROM) call journal doesn't share SIM-In this case, only the analysis of system logs will help (see section 4).

2. Settings SIM-maps: how to turn on the display of numbers

If there is no clear difference in the call log SIM-And you can set up maps to show their names or even numbers right in the interface:

1. Go to Settings. → SIM-maps and mobile networks.
2. Select Names. SIM-maps (or Management) SIM-maps in older versions).
3. Assign each card a unique name, such as "Working SIM" and "Personal SIM." Now the call log will display that name next to the number.

On some models (Poco) F4, Xiaomi 11 Lite can also be turned on here to show the number SIM-After activation, the last digit of the number will be displayed next to each call. SIM (e.g. "...789 (SIM1: +79XX..."). This is the most reliable way, but it does not work on all firmware.

If this section is not in your settings, try updating your MIUI to the latest version or using alternative calling apps (see Section 5 for those).

3. Notification analysis: where the history of missed

Missed calls are duplicated in the MIUI notification center, and sometimes more information is stored here than in the log.

• 📱 Swipe down from the top edge of the screen to open the notification bar.
• 🔍 Find the Missed Calls block and expand it. Some versions here indicate which one you want to see. SIM A call has been made (e.g., "1 missed on the SIM2").
• ⏳ If the notification has already disappeared, check Settings → Notifications → Notification history: Enable this feature in advance to avoid losing data in the future.

Critical: on Xiaomi with MIUI 14+, missed call notifications can automatically clear after a phone restart or after 24 hours.To avoid this, turn off the Auto Clean option in the notification settings.

If there is no information in the notices about SIM-map, but you remember the approximate time of the call, try to match it with the operator's logs (see the next section).

4. Advanced method: system call logs

For users who are ready to dive into technical details, MIUI maintains hidden call logs, which record which SIM each call has received, and can be accessed through an engineering menu or special applications.

Method 1: Using the USSD code

1. Open the Phone app and enter the combination: ##4636###.
2. Go to the Usage Statistics section → Phone.
3. This displays a list of recent calls with Slot ID (1 or 2 corresponds to SIM1 or SIM2).

Method 2: Using the MTK Engineer Mode application (for MediaTek processors)

• Download the app from Google Play (only for devices on MediaTek!).
• Open the Telephony → Call Logs section.
• The list will include a SIM ID column with the slot number.

⚠️ Note: Not all Xiaomi models support these methods. For example, on smartphones with a Snapdragon processor (for example, Xiaomi 13 Ultra), the engineering menu may not show data about the device. SIM-In this case, use third-party applications (section 5).

5. Third-party applications: alternative calls and analytics

If standard methods don't work, Google Play apps will come to the rescue. SIM-They're also providing advanced statistics:

• 📞 Truecaller: Shows you which one SIM You've got a call even if the number isn't saved in your contacts.
• 📊 Call Logs Backup & Restore: Keeps your call history with an indication SIM-It's a separate file, and it's useful if you want to analyze old calls.
• 🔍 SIM Toolkit: The operator’s built-in app (if installed) sometimes duplicates information about missed calls with reference to the SIM.

Example of working with Truecaller:

1. Install the application and allow access to call logs.
2. Open the "Recent" tab, and next to every call, there's an icon. SIM-slot-card.
3. For convenience, enable the option "Show call notifications" in the application settings.

If you use MIUI 15, note the "Dual Apps" app (in some regions called "Dual Apps"), which allows you to duplicate instant messengers and calls for each app. SIM-separate maps, which simplifies the analysis.

💡

Before installing third-party apps, check reviews — some of them may collect data about your contacts, prefer programs with a rating above 4.5 and downloads of 1 million.

6.Operational Support: How to Request Details

If none of the above methods worked, the last option is to request call details from your mobile operator, an official method that works 100% of the time, but has limitations:

• ⏳ Delay: Details are not provided immediately - usually within 1-3 days.
• 💰 Payment: Most operators (MTS, Beeline, Tele2) charge for the service (from 30 to 100 rubles).
• 📄 Format: Data will come in the form PDF Excel file with time, number and IMSI SIM-card to which the call was made.

How to request details:

1. For MTS: send an SMS with the text "Details" to the number 111 or use the personal account on the site.
2. For Beeline: dial *110*9# and follow the instructions.
3. For MegaFon: go to the application "MegaFon" → "My services" → "Details".
4. For Tele2: Call 611 and request details from the operator.

⚠️ Note: Details show only successful connections (response calls), missed or dropped calls may not be displayed, and the operator does not provide data on calls to the second one. SIM-card if it is from another operator.

Frequent Mistakes and How to Avoid Them

In an attempt to determine SIM-Users often make common mistakes, and here are the most common ones and how to fix them:

• 🔄 They're messing. SIM1 and SIM2: V MIUI The slots may not match the physical location of the cards in the tray. To check, insert one SIM-card to slot 1 and call it – so you determine the match.
• 📵 Ignoring operator settings: Some operators (e.g. Yota) do not share data about the data SIM-In this case, only detail will help.
• 🔋 Not updated. MIUI: In older versions (e.g, MIUI (11) display functionality SIM-- I'm not sure if you're going to get a new card. → The phone. → Updating the system.
• 📱 Use unofficial firmware: On custom ROM (For example, LineageOS, the call log may not work properly. MIUI.

2. Find the phone and select Warehouse → Clear the data.
3. Reset your smartphone. SIM-The cards will remain, but the call log will be reset.
