You may find that you have missed an important business call or text from a loved one only to discover long after that your calls were being forwarded to an unknown number unbeknownst to you. Such a case, unfortunately, happens more than you might think because of the typically overlooked call forwarding feature

Call forwarding is a great feature when you want to redirect incoming calls to another number if you’re not available, but it’s also another thing if abused or unchecked. It may cause a breach of privacy, expose sensitive conversations, and lead to missed opportunities.

Yet, the more alarming aspect is that many of the users don’t even realize that they are forwarding their calls, thus making them vulnerable to potential risks. Let’s take a look at this blog and identify how to check if your calls are being forwarded.

🔑Key Highlights
  • Dial codes like *#21# or *#62# to check if your calls are being forwarded. This helps detect potential unauthorized forwarding on your phone without having to navigate through settings.
  • If your caller ID consistently shows unknown numbers or you’re missing calls that never reach your device, it could indicate 3rd party tampering with your call forwarding settings.
  • Use deactivation codes like ##21# to stop forwarding your calls or manually turn off forwarding through your phone settings.
  • If you notice persistent unauthorized call forwarding, reach out to your carrier. They can verify any suspicious activity and ensure your number is secure.

Understanding Call Forwarding

Call forwarding is a telecommunication feature that allows incoming calls to be redirected to another phone number. There are two main types of call forwarding:

  1. Unconditional Call Forwarding: All incoming calls are forwarded to another number without ringing the original device.
  2. Conditional Call Forwarding: Calls are forwarded only in specific situations, such as:
    • When the line is busy.
    • When the call goes unanswered.
    • When the phone is unreachable (e.g., turned off or out of network coverage).

Why Should You Check for Call Forwarding?

It’s important to regularly check your call forwarding settings for the following reasons:

  • Privacy and Security: Unauthorized call forwarding can be a sign of phone hacking or tampering, leading to eavesdropping or loss of sensitive information.
  • Missed Calls: Forwarding calls unknowingly could cause you to miss important business or personal calls.
  • Unexpected Charges: If calls are being forwarded to an international or premium number, it could result in unwanted charges.
  • Better Control: Knowing your call forwarding settings ensures you have control over your phone’s communication settings.

Quick Ways to Check if Your Calls Are Being Forwarded

how to check if your calls are being forwarded.

Using MMI Codes

What Are MMI Codes?

MMI codes, which stands for “Man-Machine Interface” codes, are special sequences of numbers entered on a mobile phone, usually starting with a star (*) and hash (#) symbol, that allow users to access various information about their phone or network settings, like checking signal strength, phone number, or enabling specific features without needing to go through the phone’s menu system.

Key points about MMI codes

  • Accessing information: You can use MMI codes to retrieve details like your phone’s IMEI number (*#06#), signal strength, or network operator information.
  • Changing settings: MMI codes can also be used to modify certain phone settings, such as call forwarding, call barring, or data roaming.
  • Format: Most MMI codes follow the format *#CODE#.

After dialing each code, a message will appear on your screen showing whether call forwarding is enabled and, if so, the number your calls are being forwarded to.

Testing Manually

  1. Use another phone to call your number while your device is off or in airplane mode.
  2. Observe whether the call is forwarded to another number. If it is, call forwarding may be active on your device.

Place a test call to your number from another phone while your device is off or in airplane mode.

Observe whether the call is forwarded to another number.

How to Disable Call Forwarding

If you discover that your calls are being forwarded and you want to disable this feature, there are two primary methods: using deactivation codes or adjusting settings through your phone’s menu.

Using Deactivation Codes

Deactivation codes, also known as MMI (Man-Machine Interface) codes, allow you to quickly disable call forwarding. Simply dial the appropriate code for the type of forwarding you want to disable, then press the call button.

  • To deactivate all types of call forwarding, dial:
    ##21#
  • To disable call forwarding when unreachable, dial:
    ##62#
  • To disable call forwarding when busy, dial:
    ##67#
  • To disable call forwarding when unanswered (no response after a few rings), dial:
    ##61#

Once you dial the code, you should see a confirmation message indicating that call forwarding has been successfully disabled.

Disabling Call Forwarding from Phone Settings
