Someone may have answered this so I apologize if I duplicate the response. I actually have “family base” There’s an app in the App Store. You can actually set up times to stop calls at a certain time and begin at a certain time, you also can set up what’s called a watch list and if there’s someone you don’t want them speaking to, say a friend that may be he’s in an argument with or whomever, you will get an email or text telling you he’s been in contact with a person from your watch list. It’s a really nice feature and actually the whole family base is outstanding!!!
If he would be grounded you can also stop calls, text or any usage for a set amount of days. Also you can limit the usage of GB’s.
