How the Missed Call fraud happens?
On phone, it all starts with an unknown call claimed to be from telecom service providers like Jio, Airtel, Vodafone. BSNL etc.

After convincing you to send the unique SIM number, the scamster will tell you to press 1, 2 or simply authenticate the SIM swap. Once you press the desire number, the unique SIM number will initiate the ‘Swap’ with your telecom operator officially. For example, if you have an Airtel SIM, the scamster will use a new Airtel SIM to officially process the exchange of SIM card. Now, Airtel will send a confirmation SMS to your phone number and the scamster would want you to press 1 or 2 to authenticate the SIM Swap. With this, Airtel will understand that you have officially initiated the SIM Swap but then the attacker will end up hijacking your phone number.

Now, when the Swap is complete you will not even get to know about it.
