The Nokia Russia channel seems to be using these twins (acting as sales guys) to sell a dual SIM version of the Nokia Lumia 530 in this promo. I’m guessing I somewhat heard them say “SIM CARD ONE, SIM CARD TWO? I don’t speak Russian so I could be completely wrong.
The 530’s screen has dual SIMs in it so maybe it is right. It seems specials are available at “The Messenger” or “Связной” which is “Russia’s second largest independent handset retailer, with over 2,900 stores in Russia and Belarus”.
