How do you change a sprint phone number?

You can't "change the phone number of Sprint." Well, I suppose you could if you're a highly placed executive within the company, but otherwise no.If you're a Sprint subscriber, you still can't change it yourself, but you can call Sprint and ask them to change it for you. There's usually a fee for this sort of thing, though they might agree to waive it if there's a good reason you're changing it (threatening or harassing phone calls, for example).
