AT&T will be offering a slight increase to their data allotments on the Mobile Share Value plans starting November 2nd. The current $40 a month plan with 2GB of data will now recieve 3GB of data. The $70 4GB data allotment will get bumped to 6 GB.
It would have been nice to see them just double the allotments across the board, but any bump up is nice really. I highly doubt AT&T will be kind enough to simply migrate current customers to the new offers, so you might want to mark your calendar for November 2nd and give them a call.
