12 people want to be able to turn our kids' phones on & off remotely.

If we don't want them text, surfing the web, talking etc. @ school or in their rooms, etc...we can just turn off their phone or any time period we like. (maybe by sending a simple "On" text or "Off Text" to their phone from our phone that has the 'remote control' app. Then, if they are at a friends house or something...and we want to reach them, then we just turn it back on. This is a great ask. ;)
