I Will be getting a brand new blackberry Bold 9700 without a plan. I will use my old plan for my old phone and just put my SIM in the BB Bold. Now my question is, will this work since i am not buying the data plan? Do i have to buy the data plan in order to use the phone without any random phone charges or is this not possible? Suggestions pl0x
