ParentShield is the only Mobile Network that is perfect for children. Because it is designed for children from the ground up.
ParentShield SIM cards allow you to control bedtime remotely from your online Portal. Set Bedtime once and after this time the phone can not make or receive calls or SMS, or access Mobile Data. The Special 'Home Numbers' are the only exception as these will always work under any circumstance.
A single switch in your online Portal allows you to enable SchoolBlock. SchoolBlock stops all calls, texts and mobile data from working between the hours of 9am and 3pm. Calls to or from Home will still work to allow for any emergency situations that may arise.
