Opensignal Speed Tests

Opensignal speed tests measure your real experience of mobile connectivity and signal. The speed test runs a 10-sec download test, 10-sec upload test and ping test to determine the speed you will likely experience. The speed test runs on common internet CDN servers. The result is calculated with the middle range of samples.

Check if you're getting the network quality you're paying for from your mobile network or internet provider. Use our coverage maps to compare networks and data speed in your area. Opensignal works with WiFi mobile broadband internet.

Video Speed Tests

Slow video load time? Video buffering? More time waiting than watching? A good average network speed isn’t enough for a great video experience. Opensignal’s video test gives you the full picture of your network experience. Opensignal video tests show you exactly what to expect with HD and SD videos.

Watch a 15-sec video snippet to test and log load time, buffering, and playback issues in real-time.
Monitor how video quality changes with time and location. Review video test results in History to see if your network experience has changed over time.

Coverage Map

Opensignal’s coverage maps show signal strength down to street level using speed test and signal data from local users. With network stats on local network operators, you can check speeds ahead of a trip, find out if you will get a signal in remote areas, check your signal against others in the area to see if you’re getting the best service, arrange the best local SIM and check the signal strength when travelling.

Independent Useful Tool

I’ve been using this useful tool to test WiFi signal around the house and at friends to decide if we should change network provider. It’s an independent tool that’s easy to use and provides almost instant result for network and video performance. It also keeps useful history so you can compare different times of the day and months. I can’t relate this highly enough. 👍🏾

Good but needs improvement

Great concept and potentially very useful when choosing what mobile network to go with. However, the filter by operator is sporadic, showing only some operators in the list - it seems related to zoom level even though all are available in the currently shown area. Secondly, why is there a limit to the zoom level. All data disappears once you go further in. I’m not expecting it to be detailed or trusted to the sq meter but it needs to allow you to go deeper that it currently does. I never saw the previous version with cell tower details but I support that being brought back if it’s possible.

Great app - reveals the true speed

Opensignal is the perfect way to better understand my mobile connectivity. I’m tired of speedtest apps that use dedicated testing servers so my connection appears fast when I’m testing but then is slow when I’m actually trying to use it. I really appreciate the Opensignal methodology which shows my true, typical speed, not just the best case. And to top it off, it’s a good looking app. Great job team!!
