Hi! I'm currently using an AT&T prepaid Go Phone with a Alcatel 871A and I have the $0.25 a minute / $0.20 a text plan. It got washed, so I'm looking into a smartphone. That said, I want to keep my current plan, because I don't even use that to it's capability and going from $14 a month to $40 a month for a touchscreen is absurd. I have zero interest in data and will only use it on wifi. Basically I want it to check Facebook on break. Main Question: Can I just put my SIM card into one of the cheap-o Go Phone smartphones and use it as is? Or will it sense a smartphone and "upgrade" me? If true, would this not happen if I used an unlocked phone not from AT&T? Finally, any suggestions for a new smartphone that can use an AT&T SIM card in that is $60 or under? Again, I want it for the occasional text and to check Facebook over wifi, not gaming. Thanks for any help.
