How do i move a number from one carrier to the next?

[Oxn]

Like if i move from verizon to Sprint?

Go to Sprint and ask if they can port your current number to their network. They will let you know if it can be done or not. A fee may be charged for doing it, so ask if there's any way this can be waived if you are opening a new account with them.

Do NOT contact Verizon first. Sprint can handle it on their end.
