I have a standard Nokia phone that I use no data on, and a MiFi device for using my iPod out and about. I currently have a post pay plan for my phone, and a prepay sim for my data.
I noticed my postpay plan has a little bit of mobile data, 100MB, which is really all I need for a month. Is it possible to get a second SIM on my postpay account to use this data, rather than having two accounts? They're used at the same time.
