Android widget for toggle Mobile data.
As you can see there are other Data switcher widgets ( 7 inch screenshot has a factory built one) but they don't listen the correct network state or has ads.
This has no ads.
Widget: you will not find at Apps after download, but at Widgets! Drag to home screen for launch.
Widget: can't work from SD-Card, they need to be in Internal Storage. This has less than 1Mb size.
Tested with Android 4.0.4, and 4.2.2.
If for you doesn't work: Please send an EMAIL instead of review! First make sure, you have installed on internal storage and not SD-Card, also dragged the widget to Home screen!
