Why Android asks for permission
Before the first connection Android shows a system permission screen. This is a standard step: without it the app cannot create a protected connection on your phone.
How to install the app
Download MarcoVPN from the official source, open the app and sign in. If you do not have a plan, you can start with free mode and the location will be selected automatically.
How to choose a location
All locations are visible in the app. Available locations can be used right away, while locked ones show which plan is needed.
How to track your limit
The app shows traffic usage and warns you before the limit runs out, so you do not lose connection unexpectedly.
