The DCMA prohibits software manipulation to circumvent electronic security measures. Congress temporarily exempted wireless mobile devices from the anti-circumvention prohibitions to allow consumers to “unlock” the mobile device to change carriers. The exemption ended in January 2013 and strictly speaking, unlocking mobile devices is currently illegal under the DMCA. The Unlocking Technology Act of 2013 would amend this section of the DMCA (Section 1201) and allow consumers to unlock their personally owned devices and would protect those people and companies that develop and distribute the software that facilitates unlocking.
