I have an S3 for work and I never go over like that, but I am not a teenager. Make sure his phone automatically hits your WiFi when he is home, if not then he will probably go over his data allowance.

I have 19 y.o. at school and he pushes the limits on his plan every month since WiFi at his school is not very good. (His words). I also have a 16 y.o. and he never comes close to his limit as his phone hits the WiFi at the house as soon as it is picked up.
