One more try: there is no way to determine if the user has "connected" to the internet, because the device is almost always connected (unless the device is in a basement or something).

The RadioInfo methods just tell you how much traffic is flowing between the device and the network. I suppose you could save these values at some given point in time, then compare a future value to determine how much traffic occurred.

The CoverageInfo class will tell you what type of coverage is *available*.

Perhaps if you explain what your end-goal is, someone can make a productive suggestion.
