Z10 update overseas

Please help:

I bought the unlocked Z10 during the $199 black Friday promo from the official Blackberry online store. I am now using it overseas in Asia with a local SIM card and it hasn't updated to 10.2. xxx (whatever current official version is).

I know that the US is still on 10.1.xxx but shouldn't it auto update to the latest and greatest official 10 OS in Asia?

Thanks for any input you can help with.
