My friend wants to by this Galaxy S4 GT-I9500 that's unlocked but has this error "Sim Network been LOCK" Well I don't have the phone handy just that description and the photo below. Before committing to buy I want to know if this is fixable and a link with details. I have enough experience rooting/unlocking/custom roms with GNote 1 so I am fairly confident I can follow solution steps.
