Today, during an event held to announce Un-carrier 9.0 − Un-carrier for Business − the President & CEO of T-Mobile unveiled two new Un-carrier initiatives for consumers as well. First, with T-Mobile’s new 'Un-contract,' T-Mobile's customers will have more certainty in their wireless pricing. The company said that the customers of the 'Simple Choice' and unlimited 4G LTE plans won't see their rates raised for a minimum of two years -- as long as they reaman T-Mobile customers and keep their plans.

The Un-carrier also launched 'Carrier Freedom,' a new move where T-Mobile will now cover all outstanding phone and tablet payments up to $650 per line when customers switch to T-Mobile, in an effort to attract consumers to move from rival AT&T, Sprint or Verizon.

To take advantage of Carrier Freedom, a customer ports their number to T-Mobile’s Simple Choice plan, trades in their smartphone or tablet and buys one of our hot new smartphones. They’ll get the trade-in value right away, and a prepaid card with the balance of additional outstanding phone payments after the trade-in value when they submit the carrier’s bill to T-Mobile − up to $650 total per line on up to 10 total lines. Businesses with more than 10 lines also can also take advantage of Carrier Freedom, with bill credits up to $100 per line after the 10th line.

The Un-contract kicks in automatically on March 22 for all existing T-Mobile Simple Choice customers.
