The data allotment was supposed to automatically revert to 1 GB after January 2, 2016, but never did. Existing customers had to call T-Mobile by the end of September 2014 to benefit from this offer. In July 2014, T-Mobile offered a limited time promotion on 4 and 5 line family plans, changing their 1 GB per line unthrottled data to 2.5 GB at no extra cost. On its first anniversary in March 2014, these amounts were changed to the following: 1 GB, 3 GB, 5 GB or unlimited with the same base prices. Options for 2.5 GB or unlimited data were offered for an extra monthly fee. The contract-free Simple Choice plan, also known as Un-carrier 1.0, debuted in March 2013 by offering unlimited calling and text messaging with 500 MB of unthrottled data monthly for a base price of $50. Simple Choice - No Service Contracts (Un-carrier 1.0) 9 Un-Carrier for Business (Un-carrier 9.0).


Occasionally, the promotion is dropped all together. Generally, the advertised promotions are permanent, though some become redundant with later uncarrier innovations (for instance, the unlimited music in uncarrier 6 was moot after the move to all unlimited data plans). It debuted in March 2013, where the company introduced a new streamlined plan structure for new customers which drops contracts, subsidized phones, coverage fees for data, and early termination fees. Un-carrier is a marketing campaign created by T-Mobile US with Prophet, and advertising company Publicis.
