Geofence Policy in offline device

Geofence Policy in offline device

Hi,

my question is, what happens if the iPad is offline (out of wifi range) and leave geofence? My goal is to get the iPad lost even in this case. Can this be set?
It is also a good solution to put the iPad in lost status if disconnect from the wifi. Is this feasible?
One more question on the subject: where can I ban the iPad from turning off? The goal is not to be able to turn off the device.
In my opinion, these settings guarantee theft protection.

Thanks,
Ed
