So my aunt wanted a new phone, cheap, and I suggested the Pixi Plus for AT&T, reading that if you turned data off then you wouldn't have to get a data plan. I didn't do the bypass thing correctly and they started charging her for data, which she doesnt really want to pay. Is there any way to deactivate the device on AT&Ts network and then do the bypass thing correctly? I kinda messed this one up but want to fix it.

Thanks.
