T-Mobile’s UNcarrier event today has a lot of consumers rethinking the nature of mobile contracts, which typically hides the cost of expensive smartphones spread over the course of a few years. Most importantly, it changes the nature of how consumers pay for phones, if they so chooses.

With a minimum down payment of $99 dollars, consumers can pay $400 for the remainder of 2 years without signing a data contract. T-Mobile is also adding many more 4G devices with varying payment plans along with the popular iPhone: Samsung Galaxy S4, HTC One, Samsung Galaxy Note II, and Blackberry Z10. for example, the Nexus 4 is available for only $49.99 down with $17 per month for 24 months.

The carrier’s no contract data plan allows anyone to have an unlimited data plan for just $70 a month  without the fear of throttling or early termination fees. The company has also invested heavily in its 4G LTE network – a $4 Billion dollar technology upgrade that will launch later this year.
