Are you a heavy data user? If so, AT&T is hoping you'll look their way and consider their latest promotion. For a limited time, they're doubling up the data offered on their Mobile Share value plans.

Beginning Sunday, Sept. 28, AT&T is offering new promotional Mobile Share Value plans that include double the amount of data offered on Mobile Share Value plans with 15GB to 50 GB of data. New and existing customers who proactively sign-up by October 31 get 30GB of data for the price of 15GB – perfect for families and small business customers. AT&T customers will benefit from this offer, which includes domestic unlimited talk and text, as well as unlimited international messaging from the U.S. to select countries. And if you sign-up by October 31, you can keep your new promotional shared data amount as long as you want – there's no expiration. If you need to change your shared data amount after the promotional period ends, you will need to select from the current Mobile Value Share offers.

That's not the only offer on the table either. Also for a limited time, new customers and existing AT&T customers who activate a new line of service with a smartphone on AT&T Next will receive a $100 bill credit.
