Boost Mobile is the king of shrinkage, and proud of it.
The no-contract carrier, a Sprint subsidiary, is offering a new $45 nationwide unlimited plan for three of its feature phones: the LG Rumor Reflex, Motorola Theory, and Sanyo Innuendo, from March 29 through May 31.
Boost's plan, which gives you all the voice minutes and texting you can use -- but which does not include Web surfing or e-mail -- also incorporates the carrier's Shrinkage Plan, a scheme that rewards on-time payments.
After every six cumulative payments, your bill drops another $5 a total of three times. Therefore, in as soon as a year and a half, you could drop the $45 monthly plan down to $30 for unlimited talk and text. The same principle applies to Boost's other unlimited plans as well as for feature phones, Android phones, and BlackBerry devices.
A Boost Mobile spokesperson told CNET that more than 1 million customers have seen their monthly bill drop on the Shrinkage Plan.
