After having announced that it will join the big four national carriers in the U.S. to offer Samsung’s Galaxy Tab Android tablet, U.S. Cellular has finally revealed pricing and plan information for the tablet device. The tablet will retail for $399 on a two-year contract after a $100 mail-in rebate. Specs are similar to other carrier models for the tablet, including a 7-inch display, 1 GH processor, Android 2.2 with Android Market access, and Samsung Media Hub. There will be two data plans to pick from–a $15 per month plan will net you 200 MB of data or a $55 per month access plan for 5 GB of data. The differentiating factor between U.S. Cellular’s model and models from other carriers is the Belief Project, which means that you’ll only need to sign 1 two-year contract with the carrier ever. After the initial first two years, you can upgrade, but won’t need to sign another two-year service agreement and still receive subsidized hardware pricing. The carrier is hoping that it’s network and service will help keep customers happy, rather than the two-year contract.
