i currently have t-mobile right now (no data plan). i'm planning to buy a used blackberry curve 8320 from this seller on craigslist. can i just insert my sim card and the phone will work or do i have to buy a data plan from t-mobile also? i don't plan on using any data, but i know if i were to buy that phone from the store, they would make me purchase a data plan.

 

need t-mo sim card and data if you want to do anything besides use it for calls...
much better bb's than that out now
