If I am understanding, you were in United Arab Emirates (UAE), but your phone was logged into an account set to a different region?

If that is the case I am surprised that is the first time you ran into a geo locked app and didn't already have another Apple account for that region that you could log into. This was one of the first things I quickly learned to do if I wanted my iPhone to be useful at all when I spent many months living in a (non-Western) country. (using apps for their services)
