T-Mobile is pulling out all the stops lately as part of their new "un-carrier" strategy. As of tomorrow, eligible customers will be able to purchase a new phone with no money down and pay for it via monthly payments for the next 24 months.

The program applies to all devices including the iPhone 5 (Apple devices are usually omitted from such sales). Using that handset as an example, a customer could buy an iPhone 5 with $0 down and pay an extra $27 per month for the next two years on top of their monthly service rate.

Under the company's old plan, a user would have had to pay $145.99 down and shell out $21 per month for the next 24 months. It's only a $6 difference per month but for someone on a tight budget that can't come up with nearly $150 at the moment, it looks like a solid offer.

T-Mobile president and CEO John Legere said it is a fantastic offer that makes it easier than ever for a customer to get the latest devices. By adding Zero Down in addition to Jump, Legere implied there are zero reasons not to switch to T-Mobile this summer.

True enough, combining Zero Down with T-Mobile's new Jump plan is an interesting proposition indeed as the semi-annual down payment for a new phone was one of the least attractive aspects of the plan. Using the same Galaxy S4 example as I did in the comparison article, the two-year, four new phone price would drop from $1,320 to just $870, good for a savings of $450.

That now makes T-Mobile's offer significantly cheaper than AT&T Next and Verizon Edge over the course of a two year period assuming you take a new upgrade every chance you get. Of course, you don't really have anything to show after the two years as these plans are little more than a glorified phone rental agreement, but I digress.

It's worth noting that T-Mobile says this is a limited time promotion although I was unable to find an "end" date on their press release.
