Verizon has never forced my IL's or wife to get a data plan when they got phones last year - of course none had a PDA or the like. Just regular phones. I am off contract with Verizon and no where is it mentioned if I get a new phone I have to get a data plan (or text plan for that matter).
"Smart" phones require a data plan. Regular phones do not.
Actually nearly ALL phones Verizon offers are consdiered "smart phones" if it can access the web you need a data plan.
The reason why you and your wife weren't forced to get a data plan is because you got phones LAST year. This is a new requirement. And yes as long as you don't change your current plan you are grandfathered in. Change your plan in any way and if you have a phone that can access the web you WILL be required to get a data plan that starts out at $10 a month. Even if you never intened to use it.
In which case they can kiss my.... And I can probably get all 4 of us to switch to Cincinnatti Bell. Although we do not change the plan unless they can do a 450 minute plan instead of the 700 minute family plan. -- Brian
