AKLWestie:I mean seriously.. my $19 plan comes with 60 minutes, unlimited texts and 500MB, I'm not going to pay $25 for another 500MB.
You can buy another $19 pack. =-) So that is 500MB + 60 minutes for $19 instead of $25 for 500MB
You can't though. It renews monthly so you have to wait until it renews.
