It'll take me some time maybe, but I could give it a try. I have a bob SIM card somewhere in one of my phones (need to figure out which). Maybe over the weekend.

One maybe stupid question in return: Did she have internet access with this very SIM card on her previous phone? The reason why I'm asking is that as far as I remember, I had to activate data by sending a special code or SMS... Before, the SIM card was only valid for voice/SMS. Probably also depends on which of their card type she has, but its a possibility.
