How to avoid being charged for data plan?

My brother put his old SIM into both a Blackberry and an iPhone and our family got charged for data plan. I don't know why that happened.

I want a phone but it requires data plan, which I don't want and don't want to pay for. If I buy it online without a contract, GSM, unlocked and is with Att (my current carrier) and put my old SIM in it, will it work (as in make phone calls and text) but not charge me data plan (because it is without a contract)?

Or does the whole 2-year contract and required data plan go hand in hand, and there's no avoiding it.

Everything seems to be fine except for the fact that I can't hear anything (calls, music, etc.) unless i have the headphones plugged in.
