MyxerCodes™ work with all US carriers supported by Myxer (this is basically everybody except Nextel, Boost Mobile, and Telus Mobility).

Note that premium content - that is, content with a non-zero price - can only be purchased with a MyxerCode if the subscriber is on one of the major US carriers: AT&T, Cellular One, Sprint, T-Mobile. Users on non-major carriers who attempt to purchase content with a MyxerCode will be sent an SMS message informing them that they must make their purchase via the Myxer.com website.
