From that article: The men then sell the phones to a wholesaler in Dallas, on Harry Hines Boulevard, for about $40. He in turn ships them overseas

For some reason it must be easier to make cash-only, anonymous purchases of large quantities of these types of phones in the US than in Europe or the Middle East.
