Can I turn off the internet on my child's phone?
Not as a single remote switch. What you can do is hide the browser and the apps that need the internet, use a window so only offline apps are available at set times, or lock the device. A device with no browser and a short app list is close to offline for the child.
Parents ask this when they want the screen quiet without a fight. There are a few ways that come close, and which is right depends on what you want.
To stop web browsing, set the browser to off for that child. With no browser, and no more than 50 alternative browsers able to run, there is no way to the web. Apps that need the internet can be left off the list as well.
To make the internet disappear at set times, use a window. A night window that allows only calls and the clock, or a study window with offline books and a calculator, does the job without touching the network. The device switches by itself.
To stop everything for a while, use the remote lock from the dashboard.
Skie also blocks changes to network settings that a child might use to escape the filter, such as VPN setup, Private DNS, network reset and mobile network settings. Airplane mode can be locked too.
A note on one thing Skie does not do: a Wi-Fi on and off timer, or cutting your home router for a single device, is not a feature. That is a router setting.
Tip: if your goal is a calmer evening, a window works better than cutting the internet, because your child can still call and use an alarm.
