Something is off with your question. You say 3GB but that would mean you paid $45 plus tax for 3GB of data. Why would you do that? Why not switch plans with a higher data limit? Unless you're thinking you purchased the 3GB US Roaming package. But that is a 15 day package. Either way, it's expired and it's now gone. It says right there it expires 30 days post purchase. Not sure how anyone can miss that.
