Tom,
I just made the switch from Jitterbug to Verizon.
Call this number 800-922-0204 and ask for Randy at extension 8514. Give
him your old account number and he will walk you through the change, and
maybe keep your old number. The phone I got is the most user friendly one I
have ever had. It is model ex 55 or something like that. It talks and you
can give it voice commands, and best of all I saved us about 20 dollars a
month over our old plan.
