AT&T on Monday revealed that its shared wireless data plans will be available later this month.
AT&T customers can sign up for the plans beginning Thursday, Aug. 23.
Dallas-based AT&T is the second major U.S. wireless carrier to introduce plans that let customers share data on multiple devices. On its "Mobile Share" plans, AT&T will offer monthly data allotments ranging from 1 gigabyte to 20 GB.
Verizon Wireless already lets customers share data on up to 10 different devices and receive unlimited talking and texting through its "Share Everything Plan."
The nation's two largest wireless carriers are seeking to give customers a greater incentive to connect more devices under a strategy that could boost revenues and reduce subscriber defections. Whether subscribers will balk at the separate fees that are assessed for data and each connected device remains to be seen.
To date, Sprint Nextel and T-Mobile USA have expressed no interest in adopting shared data plans.
