Opensignal - 5G, 4G, 3G Internet & WiFi Speed Test

Opensignal is a mobile connection and network signal speed test tool that is free to use and ad-free. To offer a constant accurate evaluation of internet speed, the programme does a 5 second download test, a 5 second upload test, and a ping test. Using a speed test and data from local users, the map depicts signal strength down to the street level.
