I want to active call barring on samsung j750 but i don't know password
Call Barring is a network feature. The Password for this feature is set by network. So don't need to worry. Just call your Network Service providers and ask them for the code, they will first authenticate you and will give you your code in return.
Note: Don't get spammed by someone telling you he can give you the code.
