AT&T on Saturday dropped a quick bit of news regarding its Mobile Share Value plans, offering up double the amount of data for new and existing customers. Starting Sept. 28, customers who sign up by Oct. 31 will get 30GB of data for the price of 15GB. If your family or small business slurps a lot of data each month, this is certainly big news. Now folks have the freedom to watch even more videos, stream more music, etc.

Below is the full breakdown:

  • 15GB is now 30GB at $130 per month (+$15/month per line with AT&TNext or no term commitment ($40/month with two-year contract))
  • 20GB is now 40GB at $150 per month
  • 30GB is now 60GB at $225 per month
  • 40GB is now 80GB at $300 per month
  • 50GB is now 100GB at $375 per month

The plans also include unlimited talk and text and unlimited international messaging, so folks should be more than covered. Data can be shared with up to 10 lines for families; business customers can share between 60GB and 100GB with up to 25 lines.

The promotion will go until Oct. 31; sign-up by then and you can keep the double data indefinitely. If the amount of data is changed after the promotional period, customers are required to select from the existing Mobile Value Share plans. You have about a month to decide, but this should really be a no-brainer.

Additionally, AT&T customers who activate a new line of service with a smartphone and AT&T Next plan will get a $100 bill credit. You can visit to learn more.
