AT&T seems intent on attracting more Americans to its Mobile Share Value plans. In November, some customers on those plans started getting extra data for no additional charge; people on 2 GB plans were automatically upgraded to 3 GB, and those on 4 GB were automatically upgraded to 6 GB.
The company's Mobile Share Value plan gives customers a communal pool of data that's shared across all devices on an account. For a single smartphone and 3 GB of data on a two-year contract, the plan costs $80 a month.
AT&T's latest announcement comes as the industry battle over pricing has intensified, with many customers becoming voracious data users. Last month, T-Mobile introduced its own data rollover feature, which goes a little further by allowing customers to keep unlimited amounts of unused data in their "data stash." That free data expires a year after it rolls over into the stash. And wireless companies have spent tens of billions of dollars in a recent auction of government airwaves that are crucial for delivering data and calls smoothly and reliably.
