How it works?

Connecting a VPN is really simple . After downloading the VPN software install it on your device ,add your subcription then activate the VPN , Connect to the server you want and the VPN will do its work

When the connection is achieved, This is what happens during the connection:

1. The VPN application on your device encrypts data traffic and send it to the server through a secured route. The data sent will go through the internet service provider (ISP) , but they wont be able to access the data because of the VPN encryption.

2. The encrypted data coming from your device is decrypted on getting to the VPN server.

3. The VPN server will send the data to the internet and receive a  respond which is meant for the user.

4. The data is then encrypted by the VPN and then sent back to you.

5. The VPN software will decrypt the data so the owner of the device can actually understand and use it.

The VPN software runs in the background of your device. Your internet will be accessible normally and will not notice something different.

Therefore its necessary to trust the VPN Service that you are working with, Most VPN providers do not log in to what you do and wont store your data.

Nevertheless there are VPN services that takes the data that runs through their servers and sell the data they get to advertisers. Especially when you are working with free VPNs, Most of them are not often safe, So it is advised to research in advance before using any VPN service.

A VPN redirects your internet connection through a remote server ,this takes up time so it may slow down your internet connection . This isn’t always the case.

There are other VPNs that try their best to make your internet connection as fast as they can , in case your internet speed is restricted by your internet service provider or from another party, a VPN can make your connection faster. The VPN makes sure that this limit will no longer affect you, so you can actually make use of the connection fully.
