“Leaving my office last week, I pulled alongside a bus covered with yet another ad for AT&T’s ‘Best-Ever Pricing’ for families,”writes T-Mobile USA’s outspoken CEO John Legere in a blog post Monday.

As is his wont, Legere couldn’t resist offering a scathing critique of AT&T’s family plan, calling it“funny”because“their deal is no deal at all”compared to the pricing of T-Mobile’s Simple Choice Family Plan.

Regardless, Legere went on to announce a new competitive offering which will be launching later this month to give a family of four a total of ten gigabytes of high-speed LTE data (2.5GB each) in exchange for a cool hundred bucks per month. By comparison, AT&T’s “Best-Ever Pricing” offers four lines for $160…

As a bonus, T-Mobile’s family plan comes with the usual Uncarrier perks such as unlimited talk, text, free international data and unlimited music streaming.

The CEO laysout the math:

AT&T’s “Best-Ever Pricing” four lines for $160 vs four lines for $100 with T-Mobile—with unlimited talk, text, and data plus up to 10 GB of LTE data on our data-strong network. Plus, their “Best-Ever” deal comes with a boatload of crap – domestic overages, international roaming fees, hidden device subsidy costs, and on and on.

The $60 difference between AT&T’s and T-Mobile’s family plan translates into a $1,440 savings over the course of a two-year contract.

They even put together a handy comparison chart, seen below.

T-Mobile’s new family plan is set to launch on July 30, valid until 2016.

According to 9to5Mac, Apple Stores right before the launch of theiPhone 6this Fall will let customers purchase iPhones through major U.S. carriers’ early upgrade programs, including AT&T Next, Verizon Edge and T-Mobile Jump.

Currently, customers who want to upgrade their phones more frequently by taking advantage of these early upgrade programs have to deal directly with their carrier.

Apple’s brick-and-mortar and online stores in the United States offer customers the choice between purchasing the device with a new two-year contract at subsidized pricing, or buying an iPhone unlocked at full price.

What do you think?

Is T-Mobile’s $100 for 10GB of LTE data shared by four people a good deal?
