Not to be caught cold by recent price cuts from AT&T, and to keep up with T-Mobile's relentless UnCarrier marketing blitz, Verizon has slightly tweaked its More Everything plan to reward its more data-thirsty customers. As of now, subscribers to the company's Edge early-upgrade program who sign up for 10GB or more of data can add additional smartphones to their plan for $15. That's $5 less than the $20 it originally charged. On top of that, Big Red has also slashed the cost of its monthly access fee from $40 to $25, meaning a family of four will pay $160 a month for 10GB of data and unlimited calls and texts. That puts Verizon on a completely level playing field with AT&T, while keeping T-Mobile directly in its crosshairs.
