How to unlock incoming calls on Xiaomi Redmi phone: all methods of 2026

Do you miss important calls on your Xiaomi Redmi, although the phone correctly receives SMS and works with mobile Internet? The problem with blocking incoming calls is one of the most common among users of smartphones on MIUI. The reasons can lie in the settings of the device itself (blacklist, Do not disturb modes), and in problems on the operator or SIM-card side.

In this article, we will discuss 5 proven ways to return the ability to receive calls, from basic checks to hidden MIUI functions. Please note: if the problem occurred after a firmware update or operator change, additional actions will be required. For the Redmi Note 12, Redmi 10C and the new Redmi K60, the instructions are relevant to the features of MIUI 14/15.

1. Checking the basic settings: SIM-map and flight mode

Before you dig deep into the settings, make sure the problem isn't about basic things.

• 📶 Flight mode: Even if the indicator is not on, it is sometimes activated programmatically. Swipe your finger from top to bottom and make sure the aircraft icon is turned off.
• 📱 SIM-map: remove the tray and reinstall the card - contacts may have oxidized. On Redmi models with a hybrid slot (for example, Redmi Note 11 Pro), check if the nanoSIM is inserted correctly.
• 🔄 Reboot: Holding the power button 10 seconds before vibration will reset the temporary failures of the communication module.

If you don't get any calls after the reboot, move on to the next step. Redmi A1/A2 and budget models often get their network settings knocked down after the update - they need to be reset manually.

2. blacklist and call filtering in MIUI

MIUI automatically blocks spam calls, but sometimes the usual numbers are blacklisted to check:

1. Open the phone application → press ⋮ (three-point) → Settings → Blacklist.
2. Check the Number and Spam tabs, delete any suspicious posts.
3. In the same menu, turn off the option to Block Unknown Numbers (if enabled).

Redmi with MIUI 14+ has added Google's Call Filtering feature, which can block artificial intelligence calls to turn it off:

Settings → Applications → Application Management → Phone → Permissions → Spam and Call Filtering (disable)

⚠️ Warning: If the blacklist is blank but calls still don't go through, check out the blocking apps (like Truecaller or GetContact.

3. Reset network and APN settings

Incorrect APN settings or a failure in mobile network settings often lead to call problems.

1. Go to Settings. → SIM-maps and mobile networks → [yours SIM] → Access points (APN).
2. Press. ⋮ → Resetting to default values.
3. If the reset doesn’t help, create a new APN manually (request the operator for options).

Settings → About phone → Resetting → Resetting Wi-Fi, mobile network and Bluetooth settings

Record the current APN settings (take pictures)

Make sure that mobile data is included

- Reboot the phone after resetting

- Check balance (sometimes operators block outgoing/incoming balances at zero balance)-->

4.Firmware problems and reset to factory settings

If the calls stopped coming after the MIUI update, it could be a software glitch.

• 🔄 Remove the update: in Settings → The phone. → Update the system click on the icon ⚙️ → Remove the latest update (available within 10 days of the update).
• 📱 Reset your network settings (see previous section).
• 🚀 Resetting your phone to factory: it's a last resort, but it helps 90% of the time. → The phone. → Resetting settings → Erase all data.

⚠️ Warning: After resetting, you will have to reconfigure your fingerprint, Face Unlock and connect to Wi-Fi. Calls should start immediately after the first reboot.

5. Problems on the operator’s side: blocking and technical work

Sometimes it's not the phone that's the fault, it's the mobile operator.

• 💳 Balance and status of services: even with a positive balance, you can activate the service "Block inbox" (call support on *111# or through the operator's application).
• 📡 Technical work: check the operator’s website or its pages in social networks for accidents.
• 🔄 Replacement SIM-card: if the card is older than 5 years, it may not support modern communication standards (for example, VoLTE.

For diagnosis:

1. Insert the SIM into another phone – if the calls don’t come, the problem is definitely on the operator’s side.
2. Try calling from another number to your own - sometimes only certain directions (for example, long distance) are blocked.
