Depends on your 8 yr old. Is she mature enough to care for a tablet?? I know our kids say they want this or that, but can she handle the responsibility of it. This is not a toy and it is expensive. If you are sure this is something for her, any tablet is fine, they all come with plans. The Samsung tablets are really amazing if you want to research those.
