Easily sim unlock your Samsung Galaxy family smartphone/tablet (S, S2, S3, some S4, Tab, Tab2, Note, Note2 and variants) so you can use any other network operator. No need for unlock code on most devices: as simple as one button click, and you can change your carrier sim card !
GalaxSim Unlock is the only app that can instantly and successfully unlock new Galaxy devices. Even with recent ICS or JB roms update, your GS2, GS3, GS4 or Note2 won’t relock after reboot.
