works with a lot of other samsung models but u should check the locks first.if sp lock is active too u should deactivate it first and only then u should deactivate network lock.the non accepted sim card u insert must not have pin code.the procedure is the same but u must change "638" with "77"...tested by me *7465625*638*Code# = Enables Network lock
#7465625*638*Code# = Disables Network lock
*7465625*782*Code# = Enables Subset lock
#7465625*782*Code# = Disables Subset lock
*7465625*77*Code# = Enables SP lock
#7465625*77*Code# = Disables SP lock
*7465625*27*Code# = Enables CP lock
#7465625*27*Code# = Disables CP lock
*7465625*746*Code# = Enables SIM lock
#7465625*746*Code# = Disables SIM lock
