Dialing *#002*# on your phone instantly turns off all forms of call forwarding, whether set up intentionally or by malware. It resets your line so incoming calls and messages are no longer diverted elsewhere.
How *#002*# works on your network
This code is a standardized GSM supplementary service command recognized across most mobile networks. When entered, it sends a signal through the network’s signaling channel to the Mobile Switching Center, which manages call routing. The command tells the system to deactivate all active forwarding rules tied to your SIM profile.
Unlike navigating phone settings, *#002*# acts directly on the carrier’s network side. This means it can remove forwarding rules that may not appear in your device’s interface, especially those set remotely or by third-party access.
What types of forwarding it clears
The code removes unconditional call forwarding (CFU), where all calls go to another number, as well as conditional types like forwarding when busy, unreachable, or not answered. It also disables forwarding for data and SMS on many networks, making it a full reset for diverted services.
Because it targets the 'All Forwarding' service group, *#002*# is more comprehensive than individual codes like *#21*# (unconditional) or *#62*# (forwarding when unreachable). It’s the fastest way to ensure no hidden diversions remain active.
Why it matters for security
If someone gains temporary access to your phone, they can set up silent call or message forwarding to intercept sensitive information, including two-factor authentication codes. These diversions may not be obvious in your settings. Using *#002*# helps close these gaps by wiping all forwarding rules at the network level.
This is especially useful after installing apps with call permissions, returning from travel, or suspecting unauthorized access. While it won’t stop advanced spyware, it blocks common interception methods used in phishing and SIM-swapping attempts.
Effect on voicemail and reactivation
Many carriers use call forwarding to route unanswered calls to voicemail. After using *#002*#, this link may be broken, meaning calls will go straight to silence if not answered. You won’t lose voicemail permanently, but you’ll need to re-enable it.
To restore voicemail, dial your carrier’s setup number or re-enable forwarding through settings. Some carriers automatically reconfigure voicemail after a reset, but others require manual input. Check your provider’s instructions if calls stop going to voicemail.
Compatibility across networks and devices
The *#002*# code works on most GSM-based networks, including those using 4G LTE and 5G, as long as voice calls are supported. It’s effective on major carriers worldwide, from Europe to Asia and the Americas.
While the command is standardized, feedback after execution varies. Some phones show a confirmation message, while others display nothing. Even without a visible response, the network typically processes the command. No action is needed beyond dialing the code and pressing call.
