I've a galaxy s7 edge, which I'm sure is unlocked for UK sim usage. We are in oz and have bought an oz sim card but getting message network sim locked. Is there another code for international sim usage and if so how do you get one? Thanks
Unlocked is unlocked, it doesn't matter what sim from where. There is only one code to unlock so if you've had different sims in before the one you are trying now might have a security pin set on it.
