I want to sell my iphone so I called ATT and they told me to restore phone to factory settings and remove sim card. I removed the sim card first and then tried to restore phone but that didn't work. So, I restored the phone with the sim card in it and a message popped up that said phone was activated. Does that just mean my sim card is still activated? I just want to make sure that none of my info is on the iphone when I sell it.
Also, the att rep said I had to sell it first before I could cancel the $30 data plan. Why is that?
