Incoming calls from unwanted callers can be a real problem - from annoying marketing calls to spam and fraudulent schemes. On Androiddevices there are several ways disable the incoming call: from standard system functions to third-party applications and operator settings. But it is important to understand that “deleting” a call in the literal sense is impossible - you can only block its receipt or redirect to voicemail.

In this article we will analyze all relevant methods for different versions Android (from Android 10 to Android 14) and popular brands (Samsung, Xiaomi, Huawei, Google Pixel). You will learn how to set black listand use Do Not Disturb modes, as well as which applications will help automate spam filtering. We will pay special attention to the nuances for devices with shells One UI, MIUI i EMUI —their interfaces often differ from the “pure” Android.

1. Standard blocking via phone settings

The easiest way is to use the built-in contact blocking function. It is available on all modern smartphones, but the path to the settings may differ depending on the manufacturer.

On pure Android (for example, Google Pixel or Motorola):

  1. Open the application Phone.
  2. Go to Call log and find the number you want to block.
  3. Click on the number → Block/Report about spam.
  4. Confirm the action by selecting Block.

On Samsung (One UI):

  • 📱 Open Phone → ⋮ (three dots) → Settings.
  • 🔍 Select Blocking numbers.
  • ➕ Click Add number and enter it manually or select from the magazine.

On Xiaomi (MIUI):

  • 📞 Go to Phone → Magazine → long press on the number.
  • 🚫 Select Block → OK.
  • 🔄 To manage the list, go to Phone settings → Blocking numbers.
⚠️ Attention: On some devices Huawei (EMUI), blocking through the standard menu may not work for numbers with hidden identification (for example, “Unknown subscriber”). In this case, third-party software will be required.

2. Using Do Not Disturb mode

Function Do not disturb (DND) allows you to temporarily turn off all notifications, including calls. This method is suitable if you want to completely turn off incoming calls for a certain period (for example, at night or during a meeting).

You can activate the mode in two ways:

  • 🔕 Via quick settings panel: Swipe down from the top edge of the screen and tap the icon Do not disturb.
  • ⚙️ Via settings:
    1. Go to Settings → Sound and vibration → Do not disturb.
    2. Enable the mode and set up exceptions (for example, allow calls from favorite contacts).

On Samsung the path to the settings may look like like this: Settings → Notifications → Do Not Disturb. Here you can set a schedule for automatic activation (for example, from 23:00 to 7:00) and add exceptions for important contacts.

Manufacturer Path to "Do Not Disturb" Features
Google Pixel Settings → Sound → Do Not Disturb There is an option "Alarms only"
Samsung Settings → Notifications → Do Not Disturb Can be configured separately for calls and messages
Xiaomi Settings → Sound and vibration → Do not disturb There is a "Meeting" mode that blocks all notifications
Huawei Settings → Sound → Do not disturb Supports "Smart Schedule" by geolocation
⚠️ Attention: In Do Not Disturb mode, blocked calls do not appear in the call log. If it is important for you to save the history (for example, for work), use instead redirect to voicemail (see section 4).

3. Third-party applications for blocking calls

If standard means Android fail (for example, do not block spam numbers or hidden calls), specialized applications will come to the rescue. They offer advanced features: filtering by spammer database, automatic detection of fraudulent numbers, and even recording conversations.

Top 3 proven applications:

  • 🛡️ Truecaller - identifies spam numbers using a global database, blocks SMS and calls. The free version displays advertising.
  • 📵 Call Blocker —a simple blocker with the ability to create white/black lists and a blocking schedule.
  • 🔍 Hiya —analyzes calls in real time, integrates with the standard “Phone” application.

    • How to set up Truecaller:

    1. Download the application from Google Play and complete registration.
    2. Enable access to contacts and call log (required for work!).
    3. Go to Settings → Blocking and activate the options:
      • 📞 Block spam calls
      • 📱 Block hidden numbers

    For Call Blocker:

    1. Open the application and go to the "Black List" section.

    2. Add numbers manually or import from a magazine.
    

    3. Enable the "Block all unknown numbers" option (be careful - important calls may be blocked!).

    ⚠️ Attention: Blocking applications require permissions to access call log, contacts and SMS. Before installing, check reviews in Google Play —some apps collect user data for advertising.

    4. Redirecting calls to voicemail

    If blocking is not suitable (for example, you need to retain the ability to listen to the message), you can redirect incoming calls to voicemail. This method is useful for business users or those who expect important messages but do not want to answer calls.

    Instructions for most operators (MTS, Beeline, MegaFon, Tele2):

    1. Open the application Phone.
    2. Dial the combination:
      • 📞 *21*voice_mail_number# — for unconditional redirection.
      • 📞 *61*voice_mail_number# — if the subscriber is unavailable.
      • 📞 *67*voice_mail_number# —if busy.
  • Press the call button - a notification about successful activation will appear.

To cancel redirection, dial ##21#, ##61# or ##67# (depending on type).

Voicemail numbers from operators:

  • 📶 MTS: +74957770611 or 0820.
  • 📶 Beeline: +74959748888 or 0660.
  • 📶 MegaFon: +74955146600 or 0500.
  • 📶 Tele2: +74959747777 or 0990.
⚠️ Attention: Redirection to voicemail may be paid (especially for international numbers). Check the rates with your operator through your personal account or USSD request. *100#.

5. Blocking via SIM card settings (USSD commands)

Many operators provide the ability to block numbers directly at the SIM card level using USSD commands. This is convenient if you do not want to install additional applications or configure your smartphone.

Examples of commands for popular operators:

  • 📱 MTS:
    • 🔒 Number blocking: *111*301*number#.
    • 🔓 Unblocking: *111*302*number#.
  • 📱 Beeline:
    • 🔒 Blocking: *110*711*number#.
    • 📋 Viewing the list of blocked: *110*712#.
  • 📱 MegaFon:
    • 🔒 Blocking: *130*1*number#.
    • 🔄 Cancel: *130*2*number#.

After entering the command, you will receive a confirmation SMS. Please note that:

  • 🔢 Numbers are entered without spaces and symbols (for example, 79123456789).
  • 📌 The number of blocked numbers may be limited (usually 10–20).
  • 🔄 The blocking only applies at the operator level - when you change the SIM card, the list will be reset.
💡

Before blocking via USSD, check your balance - some operators charge a fee for this service (usually 1-3 rubles per command).

6. Features for devices with two SIM cards

If your smartphone supports Dual SIM (two SIM cards), call blocking is configured separately for each line. This is true for devices Samsung Galaxy A/Sseries, Xiaomi Redmi Note, Huawei Pseries and others.

How to set up blocking for each SIM:

  1. Open Settings → SIM cards and mobile networks.
  2. Select the SIM card for which you want to set up blocking.
  3. Go to Call settings → Blocking numbers (path may vary).
  4. Add numbers to the blacklist for a specific SIM.

On Xiaomi (MIUI):

  • 📱 Log in in Settings → SIM cards and mobile networks.
  • 📋 Select SIM → Call blocking.
  • ➕ Add numbers or enable the option Block unknown.

Important nuances:

  • 🔄 If a number is blocked on one SIM, it will not be blocked on the second - the list is not synchronized.
  • 📞 Incoming calls to a blocked number will be redirected to the voicemail of the operator of this SIM card.
  • 📵 When Do Not Disturb mode is active, blocking works for both SIMs simultaneously.
What to do if blocking does not work on the second SIM?

If the number continues to call the second SIM, check:

1. Is it added to the white list (exceptions) in the Do Not Disturb settings.

2. Does the subscriber use a different number (for example, with a different operator code).

3. Is the phone's firmware updated? In older versions there were bugs with Dual SIM. If the problem persists, try using a third-party application (for example, MIUI And EMUI There were bugs with Dual SIM.

If the problem persists, try using a third-party application (for example, Truecaller) for global blocking.
