By default, with SIM runs setup in the language matching the Region read off the SIM if available...
If this does not describe your situation, could you provide more detail?
Hey, I'm in Kuwait, bought the phone here about a year ago-Lumia 1520.
The region on my phone however used to be US and language was English(United states) on my windows 8.1.
I changed it here too after stumbling for a bit but like I said it keeps defaulting back to Arabic but the region remains United states.
