For more info see this wiki link.

Also you try to access url to verify that. If you got timeout or any connection related exception means the type of network is not available.

There is no standard way in JavaME of doing this. You might want to check custom vendor libraries, e.g. Symbian JavaME libraries.

You can try to ping a server or try to make a connection and catch the exception. But this doesn't give any indication whether the phone is generally capable of connecting to the internet or not. It just tells you, that you can't connect at that moment.

Try just making a connection and see if it throws an exception.
