I live in Canada and I bought the iPad 3G. When I put in my rogers sim card it it has some options but I can't find where to put in my credit card. It has apn, sim pin, roaming, and enable/disable options. It is connected to wifi and I turn it on. It connects and says Rogers and has full bars. When I turn off my wifi it shows the 3G symbol in the status bar and it is connected. But when I try to open something it says cannot connect. Please help I really need the 3G.
