Mobile phones have become an inseparable part of our daily lives. But did you know your phone has secret codes that can reveal important information? One of the most talked-about among them is #21#. This code remains a mystery to many. Some people think this code lets someone track their phone or enables call forwarding without their consent. But what’s the truth? Let’s find out in detail.

What Is the Secret Mobile Code #21# and How Does It Work?

The secret mobile code #21# lets you check if your calls, messages, or other data are being forwarded. Many believe this code reveals if their phone is hacked. In reality, it is a USSD code that connects with your network operator’s server and displays specific forwarding details.

When you dial #21# on your phone, your mobile operator shows whether any call forwarding or diversion is active on your number. It’s not a hacking tool; it’s an official GSM-compatible code.

What Information Can You See Using This Code?

Using the #21# code, you can see the following types of information:

• Voice Call Forwarding: Are your calls being forwarded to another number?
• SMS Forwarding: Is your text messaging being redirected?
• Data Forwarding: Is your data activity being forwarded?
• Fax and Sync: Useful for business users to know active sync services.

These insights help you confirm there are no suspicious activities on your phone. This is especially helpful if you suspect your phone is under surveillance.

Security and Precautions When Using Secret Codes

Although #21# is a safe and official code, it’s wise to follow some precautions:

• Never type codes from unknown sources.
• Install antivirus software on your phone.
• Regularly check for call forwarding or unknown active apps.

Using this code empowers you to take control of your phone’s security.
