I got my son a Galaxy Note 9 for his birthday. He's 14. I have the Note 8 and I like the chat feature because I can see if he received/read my messages. The only problem is that it only works if he has a data connection. I also monitor is WiFi usage at home to see if he is still awake past his bedtime. I don't want to take his phone and if I block his connection he can still use data. I notice that he has been turning off his WiFi and mobile data then saying he never got my texts. Is there any way to prevent him from turning off his WiFi and mobile data? As well as other settings?
