Only allow Child's iPhone to use home WiFi when at home
Is there a way to prohibit my child from turning off WiFi on his iPhone X when he is on our home WiFi network? I don't want him to have the ability to bypass my router by turning off WiFi thus enabling the mobile LTE network. I currently use Screen time restrictions but I don't see any options that will help me out with this. Does anyone know the answer or have any suggestions if iOS doesn't support this features?
Thanks in advance.
