When a scammer takes over your cellphone number and can receive all your texts and calls, this is called a SIM Swap Scam.
How this could happen
You get a text message or call that is supposedly from your mobile network provider. You are told that you are eligible for a SIM upgrade, and all you have to do is send a message to your provider and share the OTP or PIN that you receive.
Because you’re convinced that it’s real, you send the message and share the OTP or PIN.
The SIM swap was a fraud, and you lose all access to your number (including your phone signal). The scammer is now in control of your mobile number, and receives all your calls and texts.
The scammer uses your banking OTPs to confirm account actions, allowing him to approve money transfers and subscriptions.
