Is it possible to restrict or

I’m having a situation with my teenage son, he’s on my STRAIGHTTALK account with his own phone and number. I want to know if it’s possible to restrict his ability to get online via my account? Is it possible to turn allowances on or off as needed? Or do I need to physically wrestle the phone from him? Our plan still has a couple of weeks and I’m thinking of getting him the absolute lowest, even zero if possible, data plan. I won’t go into all the details of why, but teenage boy pretty much sums it up. He stays on either his pc or phone and shirking his chores, big time. Thanks in advance for any help!!
