Say you were a guardian or parent and get to decide when a child can get a phone or use a computer and get internet with it. If you wish you can also install software and change router settings to what you see fit.
Some parents decide to forbid the internet completely, others are more relaxed. Some go the helicopter route, and some do not care whatsoever what their kid does online.
What is your policy on letting a child use the internet?
Not until they’re 14, sharp.
As far as phones go, probably 14 too.
But I’m not going to get them high fancy shit like IPhones. It’s going to be a basic dumbphone.
