Someone random dickhead has been harrasing a member of my family. The number seems to be from canada. However we don’t know anyone from canada. The call came on WhatsApp. Is it possible that they were using vpn?
VPN is part of internet data routing. It’s not anything to do with telephone calls.
It is very easy to purchase a virtual telephone number, anywhere in the world. So they could just simply be in Canada, in the house next door, or across the world. They can make a call with Caller ID that says it’s coming from a Canadian number.
VoIP services (and switched IP services) can have any number you want to use.
How do you do that? A friend of mine used a number from New Jersey while he is in the Netherlands to treat another friend of mine.
