Hey everyone, I have a quick question regarding my unlimited data plan. I have the unlimited data plan since the first generation iphone with ATT. I spoke with a guy at att and he told me that I could use an upgrade and get the galaxy s3 and keep my unlimited plan, while giving my 4s to my wife. So in essence, I would keep my current sim card and just put it in the s3. Given that, he said nothing would happen to my unlimited data. Does anyone know if att will see me using a different phone and take it away? Because if that is the case, it's not worth trying it. Any advice relating to this issue is appreciated.
