NTT DoCoMo said on Friday that it would at last begin allowing device unlocks and support outside hardware. Any phone, tablet, or other device bought on the Japanese network from April 1 onwards will be unlockable for use on another carrier. Owners have to visit a DoCoMo store and pay both a 3,150 yen ($38) fee and sign a waiver understanding that the carrier's specific features won't work on another network.
