The problem can manifest itself in various ways, from a complete lack of notifications to a “silent” reset after 1-2 beeps.

In this article, we will analyze all possible causes - from banal settings MIUI before hardware malfunctions specific to specific models (e.g., Redmi Note 10 Pro or POCO X3 Pro!

If you've tried to reboot your phone or check Do Not Disturb mode, but the problem is, don't rush to bring the device to the service. 80 percent of the time, the solution is on the surface, it's just hard to see without a hint. Let's start with the obvious and gradually move on to sophisticated diagnostic methods.

1. Checking basic settings: what you might have missed

The first thing to rule out are configuration errors that users often overlook, not only do not disturb, but also specific MIUI features that can block call notifications.

Start by checking the following parameters:

• 📱 The “Do Not Disturb” mode» (DND): Even if it's turned off in the notification curtain, check for exceptions. Go to Settings. → Sounds and vibrations → Don't disturb. → Allow exceptions and make sure that the Calls item is enabled.
• 🔕 Sound profile: in MIUI There's a separate "Meetings" profile that by default disables all sounds, including calls.

A critical feature of MIUI 14+: new firmware versions have introduced a Concentration feature that can automatically turn off call notifications while sleeping or working. Its settings are hidden in Settings → Digital Well-being → Concentration.

2. Software glitches: from cache to "broken" updates

If the basic settings are fine but the calls are still not displayed, the problem may be software conflicts, most often due to:

• 🗑️ With cached phone or contact data, cleaning the cache can bring back functionality.
• 🔄 Failed update MIUI, Especially if the problem occurred immediately after the firmware upgrade.
• 🤖 Conflicts with third-party apps that have access to calls (such as recording conversations or spam blockers).

How to diagnose and eliminate:

1. Cache Clear: Go to Settings → Apps → App Management, find Phone and click Clear Cache. Do the same for Contacts and Google Play Services.
2. Reset the Phone app settings: In the same app management menu, select Settings Reset (this won’t delete your call history!).
3. Check for updates: go to Settings → About Phone → Update MIUI and install the latest patches.

If the problem has occurred after the update, try to roll back to the previous version of MIUI via Settings → About Phone → MIUI Version → Three-Dot Icon → Select an update package. To do this, download the necessary firmware from the official Xiaomi website in advance.

Attention! If not only the phone calls are missing after the update, but the mobile network is a sign of a modem failure, then only flashing through Fastboot or accessing the service will help.

Conflicts with SIM-map and network operator

Sometimes the problem is not the phone, but the phone. SIM-The map or the operator settings. Here are the typical scenarios:

• 📶 Wrong settings APN: If the access point settings are incorrectly configured, this can affect voice communication.
• 🔄 Activation of the AntiAon service from some operators (for example, MTS or Beeline), which blocks incoming calls from unidentified numbers.
• 🆔 Problems with IMS-profile: in networks 4G/5G VoLTE technology is used for voice communication, and if the profile IMS It's not a phone call.

⚠️ Attention: If after the shift SIM-The cards were called, but after a few hours they disappeared again, a sign of the deterioration of contacts. SIM-In this case, only the replacement of the tray or soldering of contacts will help.

4. Hardware malfunctions: when without service can not do

If all software methods have been tried, but the calls are still not displayed, the problem may be hardware.

• 📡 Faulty antenna module: common after falls or moisture, symptom - not only communication, but also mobile Internet is lost.
• 🔌 Oxidation of contacts SIM-cards: if the phone has been in a wet environment, the tray contacts may corrode, leading to intermittent operation SIM.

• 🛠️ Damage after repair: if you recently changed the screen, battery or back cover, could damage the antenna cables.

How to diagnose a hardware malfunction:

1. Check the engineering menu: type ##4636## in the dialer, select Phone Information and see network status. If the Service State section says Out of Service or Emergency Calls Only, the modem problem.
2. Testing with another SIM-map: if none of the SIM It does not catch the network, it confirms hardware failure.
3. Visual inspection: check if there is any on the tray SIM-maps of traces of oxidation or bent contacts.

⚠️ Warning: If the phone stopped catching the network after falling or getting moisture, do not try to disassemble it yourself! corrosion can spread to the motherboard, and then repairs will cost many times more expensive.

5. Specific problems of Xiaomi models

Some Xiaomi models have unique call display illnesses, and these are the most common.

• 📱 Redmi Note 10 Pro / POCO X3 Pro: the problem with the chip Qualcomm X51, The modem is the one that's in charge of the upgrade. MIUI 13+ The solution is the pullback. MIUI 12.5 or chip replacement.
• 📱 Mi 11 Ultra / Mi 11 Pro: a double bug SIM-It's a card when the second card stops taking calls after the reset.
• 📱 Redmi 9 / 9A: A defect in the antenna switch, which causes the phone to "not see" the network in certain bands.
• 📱 POCO F3 / F4: conflict with Wi-Fi Calling, which blocks normal calls. SIM-map.

💡

Before visiting the service, back up your data via Settings → About Phone → Backup. Some hardware repairs (such as replacing the motherboard) result in complete loss of information.

6.Firmware problems: When MIUI "gluts"

MIUI is known for its surprises, and missing calls are one of them, most often due to:

• 🔄 «Broken firmware: If the update is downloaded with an error or was interrupted, it can damage the system files responsible for phone functions.
• 🛠️ Custom firmware: Unofficial builds (e.g. xiaomi.eu or Pixel Experience) may conflict with modems.
• 🔒 Blocking. IMEI: After a failed firmware or reset, the phone may lose IMEI, Which makes it impossible to call.

How to restore the workflow:

1. Fastboot: fastboot flash all.zip fastboot reboot Use the official firmware from Xiaomi.
2. Recovery IMEI (Only for experienced users!: su setprop ril.radio.imei [IMEI_1] setprop ril.radio.imei2 [IMEI_2] IMEI You can find it on the phone box or under the battery (for models with removable battery).
3. Reset to factory settings: if the firmware is fine but the calls aren’t working, try a full reset via Settings → Additional → Restore and Reset → Reset settings.

⚠️ Attention: Recovery IMEI On some models (for example, Redmi Note 8 Pro with Mediatek chip) can block the network forever.

7. Alternative solutions: if nothing has worked

If all of the above methods fail, try the non-trivial approaches:

• 🔄 Change of firmware region: sometimes calls don't work due to incompatibility of regional settings. Try flashing Global or EEA version MIUI.
• 📱 Using a third-party app to call: install Google Phone or Truecaller and assign it to the default app for calls.
• 🔌 Disabling the function of “Double tap to wake up”: on some models, this feature conflicts with the processing of incoming calls.
• 🛠️ Replacement of the communication module: if all software methods are exhausted, only hardware repairs remain.The cost of replacing the antenna module is from 1,500 to 3,000 rubles.

💡

If calls are lost after installing custom firmware, go back to the official MIUI. Many custom builds are not optimized to work with the Xiaomi modem.
