Forum Thread: Video Call Button/Icon Missing on Galaxy S4?

Hi..I bought a Galaxy S4 AT&T and get it unlocked by using a code from internet. Currently, I am using it in New Zealand. And the problem is

it does not give me an option to make video calls on the dialpad. Inspite of the video call icon, it has a voicemail icon. Can anyone tell me if facing the same problem or having a workaround for this.
