The concept of shared data plans has been floating around in the U.S. mobile industry for a while. So far, however, only Verizon has announced plans to offer them. This idea of shared data plans is based on the various family and business plans available from almost all major carriers in which multiple lines and corresponding devices are bundled as a single plan on a single account. That allows all the devices share the same pool of minutes.
While it seems like shared data would function in a similar manner, the issue isn’t quite so clear-cut from the perspective of mobile carriers. In fact, according to AT&T CFO John Stephens, carriers still aren’t sure how to configure shared data options or how much money they would make or lose by implementing them.
