There's no 100% accurate way
1. Judging the browser header
2. Determine IP and ISP
3. Use Js+ajax to return features according to the features of the mobile browser (different versions of browsers always have something that is not supported, judging by this)
4. Other--the characteristics of the cell phone, I don't know.

That should be how to judge, look at the Android client is very good to judge.
What external programs do you need to get, guidance please!!
Mobile client, such as Android or iOS app, can determine whether the current network connection is to go WiFi or mobile network (3G, LTE, etc.)
This is the function provided by the operation system itself. It cannot judge whether you are using mobile or telecom, Unicom's network.
Simply by PHP in the remote server side is no way to judge, through the client IP address to judge is yes, but it is too difficult. Need to spend money to buy a database and update it in time.
