During the conversation, the victim is asked to dial a USSD code, often starting with 21, followed by a phone number shared by the caller.

But the moment the code is dialled, call forwarding gets activated silently on the victim’s phone.

What happens after call forwarding is activated

Once call forwarding is turned on, all incoming calls are redirected to the scammer’s number. This can be related to anything, from bank verification calls, OTP confirmation calls, to Security calls from apps like WhatsApp or Telegram. 

With access to these calls, scammers can reset passwords, approve transactions, and take full control of accounts. The victim’s phone continues to work normally, which makes the scam even harder to notice.

This is particularly dangerous because USSD codes work instantly and there is no need of the internet connection. You often get no notification when call forwarding is enabled, and most worryingly, antivirus apps and spam filters usually can’t detect it! Since it uses legitimate telecom functions, the fraud doesn’t raise immediate red flags.

Authorities have clearly warned people to never dial USSD codes starting with:
