After months of testing, AT&T has finally announced the nationwide rollout of its 3G MicroCell. Starting in mid-April and continuing over the next several months, AT&T will gradually introduce its MicroCell to new markets across the continental US. The unit will offer both 3G data and voice service and will cost each customer $149.99 for the equipment upfront. Similar to other femtocells, the AT&T MicroCell will support up to ten handsets and allow four simultaneous connections. Customers can choose to either have AT&T deduct calling plan minutes for the calls made using the MicroCell or they can purchase an add-on plan for $19.99/month which allows them to make unlimited calls through the MicroCell without using minutes from their monthly voice plan. If you choose this $19.99 plan, AT&T will reward you by offering an additional $100 rebate which brings the price of the MicroCell down to a mere $49.99. If you really want to drink the AT&T koolaid, you can also sign up for AT&T broadband service (DSL or U-Verse 1.5MB or greater) and receive a second mail in rebate for $50, bringing the final price of the device to a $100 if you select just the DSL or a cool $0 if you are eligible for both rebates. Any AT&T customers with fringe coverage interested?
