T-Mobile today rolled out a new family plan that throws out the shared data bucket and gives everyone 10GB of LTE data each.

The new plan starts at $100 for two lines with 10GB of data each. From there customers can add new lines, each with another 10GB of their own, for $20 each.

The new plan is available tomorrow and customers who sign up or switch between now and Labor Day will get the fourth line for free indefinitely. Besides no contracts or data overage fees, the new plan comes with Music Freedom, Data Stash and T-Mobile’s recently announced free roaming and calling for Canada and Mexico to and from the United States.

So the plan cost comes out to $120 for four lines with 40GB of data (10GB each). The total cost will be higher after figuring in device costs.

In announcing today’s new plan, T-Mobile CEO John Legere took aim at Verizon’s $80 10GB shared data plan.

“It’s no surprise Verizon’s spent what looks to be over $100 million in just two months promoting an $80 data plan with 10GB everyone has to share. The catch is, it’s not actually an $80 plan. You can’t actually use any of that data until you pay additional ‘line access’ fees for data you’ve already bought,” Legere said in a statement.

T-Mobile COO Mike Sievert on Monday hinted at the new plan in an interview with CNET.

The new family plan at T-Mobile marks a considerable increase to the amount of data the carrier was offering with its $100 promotional plan for four lines and 10GB of data (2.5GB each).
