I am totally new to wireless email and pda's.

My question is this. I currently have a personal Verizon phone with a basic
voice only plan. I have a Blackberry Enterprise Server at work. My current
Verizon contract expired so I can get nice discount a Blackery.

Do I need to upgrade my Verizon plan in order to send and recieve emails
using my Blackbery Enterprise server at work?

Thank you for your help.
