Have some IPADS for classroom use. I don't see any way to prevent the IPADS from getting on the internet. None of the apps need the internet, and when a child loads an app, the app prompts them to download updates (which they can't), so then the apps refuse to work until the updates complete. I take the IPADS out and do the updates myself every few months, between those times the IPADS have no need to be on the internet. The SSID is set up by the school, so they join automatically, and I don't have the password. Is there a way to prevent a child from switching on the WIFI after I've switched it off? I've looked under restrictions and I don't see that ability.
