VZW does not charge PERIOD for ESN changes.

Depending on your plan, things can be easy or tricky when moving from a PDA to a dumbphone.

If you're on an America's Choice/Nationwide Basic or Select with an À la carte (29.99/44.99) data plan it'll be a piece of cake. Call in and do an ESN change to the Gz'One. Your data plan will fall off and be prorated. You will receive a credit for the days that you did not use the service on your next bill. When you put the PDA back on, the plan will go back on. Again, with a prorated amount for the days that it was actually active on the account.

If you're on a Nationwide PDA/Smartphone plan with an included data package, you must change to a normal calling plan on demand which will prorate your minute allotment and the monthly charges. Due to how confusing the bill ends up being and not having your full minute allotment, I wouldn't recommend this unless you absolutely need the Gz'One on there (i.e. the PDA is broken).
