Customers can select one of the new shared data plans or choose one of AT&T’s existing individual or family plans. Current customers are not required to switch to the new plans, but can choose to do so without a contract extension. There are no changes to AT&T’s device upgrade policy, which means customers eligible to upgrade to AT&T’s best device price are not required to switch plans. The new plans will also be available for business customers.

With AT&T Mobile Share plans, customers start by choosing how much data they want each month, then choose up to 10 devices to attach to their shared plan, one of which must be a smartphone. Each plan includes tethering and unlimited domestic calls and texts for smartphones and basic or quick messaging phones. The larger the data bucket you choose, the less you pay per gigabyte and the less you pay for each smartphone added to the shared plan
