I would like to try visible and have them assign me a phone number but then if I like it I would like to port my other phone number to visible but not when I first get the card. Can this be done. I will use the visible card in another phone and still keep my cricket card in a different phone and not cancel cricket until I'm sure I like visible. At that time. I would like to port my cricket number over to visible and get rid of the phone number visible assigns me. Is this simple to do?
