Continuing the carrier war that has seen the major U.S. wireless companies offering various forms of bonus data allotments in recent months, AT&T today announced a new limited-time promotion that bumps the 10 GB data package ($100 per month plus device access charges) to 15 GB.

The promotional 15GB Mobile Share Value plan at the 10GB price is available to new and existing AT&T consumer and business customers and includes domestic unlimited talk and text, and the nation’s most reliable 4G LTE network. Customers can easily take advantage of this new offer by visiting att.com and our current AT&T customers can also select the new plan via their myAT&T app. Additionally, AT&T customers can get unlimited international messaging (text, picture and video) on all Mobile Share Value plans for no additional cost. Unlimited international messaging includes messages sent from the U.S., Puerto Rico and U.S. Virgin Islands to more than 190 countries for text messages and 120 countries for picture & video messages.



Monthly smartphone device access charges are $40 for those on two-year contracts or $15 for those on AT&T Next or who purchased their devices at full price. Tablets carry a $10 per month access fee.

AT&T's latest promotion comes as the carrier continues to offer its double data promotion on higher-tier plans. Under that deal, users on base plans ranging from 15 to 50 GB can receive double the amount of data per month. The new promotion for upgrading the 10 GB plan to 15 GB begins tomorrow, while the double data promotion on higher-level plans is ongoing. AT&T advertises both as being "limited time" promotions, but is not currently specifying an end date for either one.
