Reply To: Need permission from parents at 21?

If you can afford it, you can also get a second cheap phone to bring with your while you leave the parental supervision phone at home.

Yeah, as long as your parents are supporting you, you’re under some amount of obligation to follow their rules. But you’re under no obligation to report everything to them. Parents with unreasonable demands should expect their children to wriggle around them, especially when those children are grown-ass adults.
