Lightbulb [Q] Walkman App Music unlimited problem

Hi there, I purchased a Xperia Z Ultra from Hong kong, its running on android 4.2.2 at the moment, I've updated the walkman app but I can't find the option to sign into music unlimited.

I'm also missing the option in the settings menu to sign into a Sony entertainment account.

Anyone have a clue why?
