I'm looked at a lot of info on these forums, some of it conflicting, so I'm looking for some answers from people who themselves use an iPhone without a data plan. My brother will give me his old original iPhone, and I do not want to pay for the data plan. Yes, I know how nice it is to have internet access everywhere, and yes, I'm aware I won't be able to use visual voice mail. I just want a smart phone that I can have wifi access on, and it's nice that I can have an iPhone for free. I am currently an AT&T costumer and have a SIM card in my current phone. How do I: Use the iPhone with my sim card? Keep AT&T from automatically adding a data plan to my bill? Any other info you think I need would be very helpful. Thanks!
