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.

Availability Stats

Opensignal calculates the time you’ve spent on 3G & 4G/LTE or had no signal. This shows your network availability in the places you use your phone the most.

See where you are getting 3G & 4G/LTE and check you’re getting the service you’re paying for from your network provider. If not, use the data to prove connectivity and signal issues to your mobile operator.

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 searching for accommodation or travelling.
