Service is a very generic term. Please be more specific.
In general, there isn't any direct way to check the services available in a device. By service, if you are referring to communication protocols available in a device, there is a workaround.
You can try to connect using a protocol and if it throws a ConnectionNotFoundException, then the device does not support that protocol. Otherwise, it does. To my knowledge, there is no direct API as such.
Other than that, you can use the MIDlet.platformRequest() and the Display class APIs to do some simple tasks such as vibration, backlight flickering, making phone calls, etc., if you consider them as services.
