Do VPNs reduce charges for long-distance telephone calls?

No, VPNs don't have any impact on telephone charges regarding calls. The truth is that VPNs allow access to remote servers, which is usually used to improve the browsing experience and improve the level of security. However, there's still a way to get lower phone bills with a VPN by changing your IP address. Namely, some telephone providers offer lower fees and cheaper packages for users residing in specific countries. So, consider trying out a couple of different VPN servers in certain countries, and then finding the best price. This also happens with Airbnb bookings and airline flights.
