A Boost Mobile unlock code is a code that allows a mobile phone to be used on other compatible carriers in addition to Boost Mobile. Unlock codes are specific to each phone.
As of 2014, Boost Mobile states that it does not provide unlock codes for its devices, but that it will begin to do so by Feb. 11, 2015. Unlock codes for some devices are available from third-party services for a fee; which services provide codes and what the fee is varies by the type of device. Even after unlocking, Boost Mobile phones must be used on a CDMA-compatible network such as Sprint.
