If I buy a Blackberry paid in full, do I need a data plan?

Kellie Waycott: If I try to tell them I'm pretty much trying to avoid paying, they'll of course give me the answer that I DO need to pay a data plan.Pretty much, what I mean is that I have one of those cheap phones. For my birthday I'm getting a blackberry that is bought for the full price - around $400. Now, when I switch over my sim card from my old phone to the new phone -- will TMOBILE detect that I now have a smartphone and begin charging me for a data plan -- even if I don't use email/internet on my phone?...Show more

Irving Jordahl: it sucks... on all smartphones and PDAs you have to have a data plan! i have looked into it a milliion times..

Micah Schwarcz: What do you mean full? If you pay the no-contract plan, then I don't think you need a data plan. Otherwise, possibly. Contact your service provider for an accurate answer.
