With 3G Test, you can compare 3G network conditions even with your friends who are not using the same smartphone as yours!

Using 3G Test, you will have a good knowledge of your smartphone's 3G network properties, such as local / global / gateway IP addresses, upload / download bandwidth (kbps), signal strength, DNS lookup latency (ms), PING latencies (ms), TCP connection establishment latencies (ms), HTTP benchmark downloading latencies (ms), and much more.

You can also easily diagnose any network problems, even some hidden traffic policies imposed by your cellular carriers. For example, you can test whether BitTorrrent traffic is blocked by your ISP. You can also test whether FTP, SSH, POP, SMTP, HTTPS ports are blocked by your ISP or not.

All the results are refreshed each time you run our tool, so we encourage you to run it at different time and different locations, in this way, you can compare the scores of your 3G network at different times of day and at different locations.

This is an application written in C++. In this application, we implemented basic functions such as Ping, Traceroute, and Ipconfig, so that you can know basic network properties of your phone, such as IP address, Gateway, Ping round trip time, DNS lookup time. Besides these information, our application can also help users get more fine-grained information. For example, we help users tell whether their carrier differentiates any kind of application traffic. To achieve this, we emulate the traffic of BitTorrent. Also, our application attemps to detect the existence of HTTP proxy caching and compression.
