I go into connections and change the Verizon #777 by adding two random numbers so it cannot connect and is easy to revert back.
Remember at a penny and a half a kilobyte it will add up VERY quickly. So quickly that if you use it for just a few websites a day it will add up to more then the $44/mo for the unlimited. WiFi at home and work and free McDonalds wifi with VZW I can pretty much avoid all data charges. Just don;t eat to many burgers
I don;t believe MMS pics data counts aginst the data plan but I could be wrong so verify.
