The essence is simple: you install a program that establishes a connection to a remote server with which you, as it were, access the Internet. Servers are usually located in countries of different countries, which allows you to access sites and services available in a future state, deceive targeted advertising algorithms, and so on. The signal in a VPN is usually encrypted with fairly serious algorithms - so there is less chance that someone will “read” your traffic (although there are those who accuse VPN services of being structured with structures from different countries).

Paid and free VPNs are available. The former have higher speed and lower latency, provide a larger selection of country servers, as well as simultaneous connection to multiple devices (for example, a PC and a smartphone). The latter are not always stable, often have limited monthly traffic and often accumulate ads.

Free VPNs
ProtonVPN
VPN for PC and smartphones with the ability to connect to servers for free in three countries: the Netherlands, the USA and Japan.

ProtonVPN, in addition to being free, has three tariff plans: Basic (4 euros, 1 device and more than 40 countries), Plus (8 euros, 63 countries, 3 devices and maximum speed) and Visionary (all Plus features and a ProtonMail Visionary account with end-to-end encryption Email). Australia). You can pay in two ways - by Visa or Master Card or via PayPal.
