Dialing *#21# on your phone is a common way to check call forwarding settings. Contrary to popular belief, it does not reveal if your phone is being tapped. Instead, it provides information about call forwarding status, specifically whether your calls are being forwarded to another number. This feature is part of the Global System for Mobile Communications (GSM) standard, used by many mobile networks worldwide.
What Does Dialing *#21# Do?
When you dial *#21# on your mobile device, you are accessing a network service code that checks the status of call forwarding settings. This code is used to determine if your incoming calls are being redirected to another number, which can be useful if you’re unsure whether you’ve set up call forwarding.
How to Use *#21# Effectively?
To use the *#21# code, simply open your phone’s dialer, enter the code, and press the call button. Your phone will then display a message indicating the status of call forwarding for various services, such as voice calls, data calls, and more.
- Voice Call Forwarding: Check if voice calls are being forwarded.
- Data Call Forwarding: Verify the status of data call forwarding.
- Fax Call Forwarding: Some devices may show fax call forwarding status.
Is *#21# the Same on All Devices?
While *#21# is a standard code for GSM networks, its functionality may vary slightly depending on your phone’s operating system and your mobile carrier. For instance, some carriers might not support this code, or the information displayed might differ.
Common Misconceptions About *#21#
Does *#21# Reveal If Your Phone Is Tapped?
A common myth is that *#21# can tell you if your phone is being tapped or monitored. This is not true. The code is solely for checking call forwarding settings and has no capability to detect phone tapping or surveillance.
Can *#21# Fix Call Forwarding Issues?
Using *#21# can help you identify if call forwarding is active, but it does not allow you to change or disable these settings. To modify call forwarding, you typically need to access your phone’s settings or use specific codes provided by your carrier.
How to Disable Call Forwarding?
If you discover that call forwarding is enabled and you want to disable it, you can usually do so through your phone’s settings or by using a specific code such as ##002#. This code is commonly used to cancel all call forwarding settings.
