How did we collect data for the ranking?

The measurements are collected from users using our mobile application. It allows us to measure the basic parameters of the mobile network – including the level and quality of the signal depending on the technology in which the mobile device works, information about the mobile network operator or the country where the smartphone is located. In addition, on-demand Internet speed measurements are taken during downloads and uploads, as well as a latency test.

When the application notes a low-quality voice call, lack of mobile Internet service or other service, it has the ability to report the user’s current position where the service problem occurred.
