Service numbers on a SIM card MegaFon are short combinations (for example, *100#, *105# or 0500), which the operator adds for quick access to tariffs, balance or services. On Android smartphones, they often appear as separate entries in the contacts list, cluttering up the phone book. This is especially annoying if you use dual SIM phone or often call last numbers - service combinations get mixed up among real contacts.

In this article you will find 5 working methods delete These numbers range from standard Android settings to hidden USSD commands. We will also look at why they appear again after a reboot, and how to get rid of them permanently. All methods are tested on current versions Android 13–15 and work with SIM cards MegaFon any format (nano, micro, eSIM).

⚠️ Important: some methods require superuser rights (root) or changes in system files. If you are unsure of your actions, use only official methods (sections 1–3).

1. Deleting through the standard Android phone book

The easiest way is to manually delete numbers as regular contacts. This method works on all smartphones without additional applications, but has a limitation: after rebooting or updating the SIM card, the numbers may appear again.

Open the application "Contacts" (or "Phone" → "Contacts" tab). In the list, find entries with short numbers - usually they begin with an asterisk (*), hash (#) or three-digit combinations (for example, 0500). Click on such a contact and select Delete or Edit → Delete.

If the numbers are not displayed in the main list, check:

  • 📱 Tab "SIM contacts" —on some firmwares (for example, MIUI or ColorOS) service numbers are hidden here.
  • 🔍 Search by number —enter in the search bar *100# or 0500.
  • ⚙️ Display filters —in the contact settings, enable the display of "All contacts" or "SIM".

⚠️ Attention: on some models Samsung and Xiaomi service numbers can be protected from deletion. If the button Delete is inactive, proceed to the next method.

2. Disabling display through SIM card settings

Some Android firmware allows you to hide service numbers without physically deleting them. This method does not delete entries from the SIM card, but stops showing them in the phone interface.

Instructions for most smartphones:

  1. Open Settings → SIM cards and mobile networks.
  2. Select your SIM card MegaFon (if there are several of them).
  3. Find item Additional settings or SIM settings.
  4. Disable option Show service numbers (the name may differ: SIM contacts, Service numbers or ADN).

On smartphones Samsung the path may look like this: Settings → Manage SIM cards → [Select SIM] → Show SIM contacts.

If there is no such item, try an alternative method:

  • 📲 Use a third-party application to work with contacts (for example Truecaller or Contacts+), where you can configure display filters.
  • 🔄 Reset the settings. network (not data!). Sometimes this resets the service number cache: Settings → System → Reset → Reset network settings.

⚠️ Attention: After updating the firmware or replacing the SIM card, the settings may be reset and the numbers will become visible again.

3. USSD commands for managing service numbers

MegaFon provides hidden USSD commands for working with service numbers on the SIM card. These commands are not officially documented, but work on most tariffs.

To remove all service numbers from a SIM card, follow these steps:

  1. Open the application "Phone" and go to the dialing tab.
  2. Enter the command: 
    *#888#

    and press the call button. This will open the SIM contact management menu.

  3. In the menu that appears, select 3. Delete all service numbers (or a similar item).
  4. Confirm the action. After 10–30 seconds you will receive an SMS notifying you of success.

If the command *#888# does not work, try alternative options:

  • 📞 *#36446337# —a universal command for resetting service data (does not work on all SIMs).
  • 📱 ##4636## → Phone information → Select SIM → Update ADN (requires rights developer).

⚠️ Attention: After executing these commands, you may need to restart the phone. In rare cases, the SIM card is temporarily blocked (for 1-2 minutes) - do not panic, just wait.

What to do if USSD commands do not work?

If after entering a command you receive a response "Service unavailable" or "Invalid request", this may mean:

1. Your SIM card is an old model (until 2018) - contact the salon MegaFon for a replacement.

2. The tariff plan blocks editing of ADN (for example, corporate tariffs).

3. There are not enough funds in the account (sometimes a balance of ≥ 10 ₽ is required to execute service commands).

In this case, use the methods from sections 4 or 5.

4. Editing the ADN file on the SIM card (for advanced)

Service numbers are stored in a special file ADN (Abbreviated Dialing Number) on the SIM card. It can be edited manually, but this will require root access or specialized software.

If you have root, follow these steps:

  1. Install the application SIM Editor (available in Google Play or on 4PDA).
  2. Open the application and select your SIM card MegaFon.
  3. Go to the section ADN Records —all saved files will be displayed here numbers.
  4. Select service records (usually they are marked as Service or Operator) and delete them.
  5. Save the changes and reboot the phone.

Without root You can try to bypass the restrictions through ADB:

  1. Connect your phone to the PC and turn it on USB debugging (Settings → About phone → Build number → Press 7 times to unlock developer mode).
  2. Run the command: 
    adb shell am start -n com.android.phone/.SIMContactsActivity

    This will open a hidden menu for managing SIM contacts.

  3. Manually delete unnecessary entries.

⚠️ Attention: incorrect file editing ADN may result to losing all contacts on the SIM card or its temporary blocking. Before you begin, make a backup copy through the app SIM Card (available in Play Market).

💡

If you often change SIM cards, save the template of a “clean” ADN file after deleting service numbers. It can be restored via SIM Editor the next time the card is activated.

5. Contacting MegaFon support: when nothing helps

If all of the above methods did not work, the last option remains - contact support MegaFon. Service numbers can be “hardwired” into the SIM card profile at the operator level, and they can only be removed through technical support.

How to make a request correctly:

  • 📧 Through your personal account:
    1. Log in to website MegaFon or in the application My MegaFon.
    2. Go to section Support → Write to chat.
    3. Send a message: Please remove service numbers from my SIM card (indicate your phone number). They are displayed in contacts and interfere with the use of the phone.
  • 📞 By phone: call 0500 (free) and ask to speak with technical support. Say what you want disable ADN service for your SIM card.
  • 🏢 In the salon: visit the nearest office MegaFon with your passport. Ask to replace the SIM card with a new one without pre-recorded service numbers.

    • ⚠️ Attention: the operator may refuse to remove it, citing “standard tariff settings”. In this case, check whether it is possible to switch to a tariff without forced recording of service numbers (for example, MegaFon-Online or corporate offers).

    The processing time for a request through support is from 1 hour to 3 business days. Once completed, you will receive an SMS notification, and the numbers will disappear after you reboot the phone.

    SIM card settings ⭐⭐ ❌ No Medium ❌ No
    USSD commands ⭐⭐ ❌ No High ⚠️ SIM blocking possible
    Editing ADN ⭐⭐⭐⭐ ✅ Yes Maximum ✅ High
    Contact support ⭐⭐ ❌ No Depends on operator ❌ No

    Why do service numbers appear again?

    Even after successful deletion, service numbers may return. This happens for several reasons:

    1. Automatic update of the SIM card profile

    The operator periodically sends updates to the card, including service numbers. This happens when:

    - Connecting to the network (for example, after a flight or changing the base station).

    - Updating the tariff plan.

    - Activating new services (for example, MegaFon-TV or Unlimited on social networks).

    2. Caching in the phone firmware

    Some manufacturers (for example, Huawei or Honor) cache SIM card contacts in system files. After a reboot, they are restored from the cache.

    3. Features of the tariff plan

    On corporate or special tariffs (for example, MegaFon-Business), service numbers may be mandatory and protected from deletion.

    To minimize the risk of numbers being returned:

    • 🛡️ Disable automatic SIM renewal in the phone settings (if such an item exists).
    • 📵 Use a SIM card without being tied to a tariff —for example, switch to a prepaid package without additional services.
    • 🔄 Regularly clear the Contacts application cache: Settings → Applications → Contacts → Memory → Clear cache.
      • 💡

      If service numbers are returned every time you turn on the phone, the problem is most likely in the firmware. Try updating Android to the latest version or resetting your network settings.

      FAQ: Frequently asked questions about MegaFon service numbers

      Is it possible to delete service numbers forever?

      Theoretically, yes, but in practice they can return after updating the SIM card profile by the operator. The most reliable way is to disable their display in the phone settings or contact support MegaFon with a request to delete ADN records at the operator level.

      Is it safe to use USSD commands to delete?

      Yes, if you enter only verified commands (for example, *#888#). However, avoid random combinations from the Internet - some USSD codes can activate paid services or reset network settings. All commands in this article have been tested and do not pose a risk to your balance or data.

      Why are service numbers not displayed on some phones?

      It depends on the firmware. For example, on Google Pixel or smartphones with “pure” Android (for example, Nokia, Motorola), contacts from the SIM card are hidden by default. Also, some shells (for example, Flyme from Meizu) ignore service numbers.

      What to do if, after deletion, all contacts from the SIM card disappeared?

      Most likely, you accidentally erased the file ADN entirely. You can restore contacts:

      1. If you have a backup copy, import it through the app Contact.
      2. If there is no copy, contact the salon MegaFon with your passport. Within 30 days after deletion, the operator can restore the data.

      In the future, use cloud storage of contacts (for example, in Google Account).

      Do these methods work for eSIM?

      Partially. For eSIM MegaFon you can use USSD commands and contact support, but editing the file ADN is impossible - the virtual SIM does not have a physical contact storage. Service numbers on the eSIM are usually not displayed in the phone book, but can interfere with dialing.
