AT&T has announced its new Mobile Share plans with Unlimited Talk & Text. Designed for customers with multiple devices, the plans offer a set amount of data along with unlimited talk and text; customers are also charged for every device that’s added to the plan. Plans start at $40 for 1GB of monthly data and go up to $200 for 20GB, while the cost of adding each smartphone to the plan goes down as the data amounts rise—each smartphone costs $45 on the 1GB plan, but only $30 when you choose one of the three most expensive plans. In addition, customers can add basic phones to their plans for $30 a month, laptops, netbooks, and LaptopConnect cards for $20 a month, and, most importantly for iPad users, tablets and gaming devices for just $10 a month; additional data will be charged at a rate of $15 per GB. AT&T’s new Mobile Share plans will be available in late August.
