When it comes to checking the upload and download speeds of your Internet connection, the most common and popular method is to use SpeedTest.net. SpeedTest has a dedicated app for Windows Phone users, but now Microsoft research team has released a new app called Network Speed Test, which can provide you detailed information about the upload and download speeds of your internet connections.
The app is pretty similar to SpeedTest.net app and checks for all the parameters including delay, download speed, upload speed and additional ones like packet loss.
You can view the history of all the tests performed using the app. When you test a network connection using the App, certain characteristics of your device and the network connection will be sent to Microsoft to help improve our understanding of network quality and availability.
While the interface of the app is very simple and clean, it does not have the ability to share your test results like SpeedTest.net app. But overall, the app is handy to double check the network speeds.
