If you have been receiving calls and messages from random international numbers on WhatsApp, be on your guard as it’s an indication that you have been targeted by scammers.
Although they carry the country regulations, the calls can be made from any part of the world as WhatsApp calls are done via the internet and there are agents that sell international numbers for WhatsApp calls in different cities.
If you respond to these calls or messages on WhatsApp, the person on the other side is likely to offer a appointment that sounds lucrative with little effort, but may ultimately end with you losing all your banknotes.
