The plans offer AT&T customers unlimited talk and text monthly, plus whatever amount of data they sign for. In addition to the price of the data, there is a cost for each phone connected to a particular tier. For example, with the 300MB plan, each smartphone joining will cost $50 a month. For the new 2GB plan, it will cost you $45 monthly per phone signed up for that tier.
Additionally, AT&T also has announced the pricing on the Nokia Lumia 520 for its pre-paid GoPhone service. This is essentially the same model that T-Mobile's pre-paid service has been selling out as the Nokia Lumia 521. The Nokia Lumia 520 will be $99.99 with no contract necessary. It is a low-end model, but does include some pretty cool features including Cinemagraph that brings motion to your still shots. The camera has the ability to capture super-wide-angled pictures, and the Smart Shoot feature lets you choose from 5 different shots of the same scene to put together the best picture. Nokia's mapping and navigation apps are also included.
The Nokia Lumia 520 for GoPhone will have HSPA+ connectivity, but will not hook up to AT&T's LTE network. The phone will be available on July 26th.
