AT&T has finally announced an Augsust 23rd launch date for their shared data plans called Mobile Share. This is a new set of plans to choose from so you are not forced into this new plan, it is up to you. The plan supports up to 10 devices (smartphones, tablets, laptops/netbooks), get unlimited talk, unlimited text and you can share anywhere from 1GB to 20GB of data. In fact, if you put this plan side-by-side to Verizon’s Share Everything plan, it’s very similar. However, on AT&T’s plan, you have to have a smartphone. So before you make the switch, check out your family’s data usage and see how it would affect the plan with this tool. Click below to view the full blog post.
