"Tether UP!" mantiene la inmovilización activa mediante la supervisión del estado de tethering wifi.
"Tether UP!" keeps wifi tethering active by periodic monitoring the tethering state.
Once activated, the app can be closed and recalled by its own icon on the notification bar.
The service (if activated) is started at boot, allowing wifi tethering since the device startup.
Activating the wifi connection during "Tether UP!" wifi tethering suspends the tethering until wifi is deactivated.
