No option to turn on/off my number in outgoing calls

Question

Hi, I have recently purchased an unlocked Samsung galaxy S5 from South Korea. When I go in to call settings/more settings to enable me to display my number in outgoing calls, the only option that comes up is Auto area code. That's it, nothing else. Can this be rectified?
Thanks
Wayne.

Your phone needs to be reprogrammed to your market (country).
The technicians at Samsung customer service should be able to do it.
But you have a older model phone. 
And the question is will they want to!
You should give them a call and try anyway.  But they might recommend that you purchase a new device!
If they say they can't help you, 
And this is the only problem you have with the s5 then just use it as is!
