BlackBerry 10 devices are here, and people may be wondering how and what service and special data plans they made need. Unlike previous devices, BlackBerry 10 phones, including the Z10, won't require tier plans with BlackBerry Internet Service or BlackBerry Enterprise Server support in order to work. Overall it should end up cheaper as long as carriers don't hike prices to make up for loss. Source: CrackBerry
