How long should I pay sons iphone bill I got him a year and a half ago for Graduation? He is 20?

My ex thinks I'm wrong because I never stated I would quit paying monthly bill.
I let him keep iPhone because it was a Graduation present. Cann someone please help

Does he have a job? If yes, then for ZERO more days.

A graduation present is a one-time thing. I would have paid it for one year (or whatever the length of the contract is), and then told him the present is over.

If he insists that you keep paying, then explain to him that this is going to be his birthday and Christmas present every year - nothing else.

It's time junior put on his big-boy pants and started earning what he wants.

By the time he's 40, he should be able to handle the responsibility.

Minus two years ago…

He should be paying his own way at this time
tell him once he is 21 it will be time for him to pay his own phone bill

some places do have separate bills for plans like the Framily plan offered by one
