There's a whole bunch of cellphones in my room (15 in total) and during some days in the night I'd like to cut the network connection to all of them at once so they don't disturb me, doing this one by one would definitely (and has been taking) a lot of time, So I'd like to know if there is a PC software, that cuts off the network (NOTE: NOT THE WLAN NETWORK, the whole cellphone network) of these cellphones? I'd prefer open source softwares if possible, though please recommend any softwares.
There is a app called "tasker" which can switch your phones into airplane mode. You only have to decide how to trigger it. You make it time triggered. Or triggered by a android intent. Or when a special email arrives in the K9 mail client. Or you could use notifymyandroid.com to trigger it in tasker. Or you could do it by a SMS. Many possibilities.
I would recommend setting up Quiet Hours on all of your phones which will block calls within a certain timeframe.
