Cara menggunakan, ada 2 CARA

ConnectionStatus cs = new ConnectionStatus(CONTEXT);
// CARA 1: cek apakah data seluler aktif
boolean isDatacellActivated=cs.isNetworkAvailable();
// CARA 2: cek apakah data selular bisa konek (ada kuota) secara async
cs.setOnStatusListener(new ConnectionStatus.onStatus(){
							@Override
							public void gotStatus(boolean isOnline) {
								  // do action here
							}
						});
