Yes, just make sure the watch is set up correctly. During lesson times, you can set it to "Do not disturb" mode in the LAMAX Tracking application (Menu -> Device settings -> Do not disturb mode "from-to"). In this mode the child cannot play with the watch (scroll through menus, etc.), no one can call the watch and it can't make unwanted sounds which might disturb the lessons. The only thing that remains functional is the SOS function.
So if you set "Do not disturb" mode correctly, there is no reason why a child can’t wear the watch in school or kindergarten. And if the teacher has a problem with it, just explain this feature to them.
