Without taking out a smartphone from your bag, you can be turned on or off the tethering feature simply by be ringing the phone.
In my environment this app is working correctly. However, depending on the model it may not work. Please note.
●By making a call from a phone that has been registered, this app will enable the tethering of the terminal.
●Because it operates only ring the phone, you do not need to call. There is no charge for the phone.
●During an incoming call from a registered phone, ringtone will not be heard.
●Upon receiving an incoming call, if tethering feature is off this app turns it on. If it is on, this app turns it off.
● In a terminal equipped with WiMAX, this app turns on or off the WiMAX feature at the same time as the tethering feature. (Tested on EVO3D)
