The 920 and the lower-priced 820, both running on Microsoft’s new Windows Phone 8 operating system, were introduced at a press event in New York on Wednesday.
At that point CEO Stephen Elop refused to specify a shipping date or price, saying simply that the phones would be out sometime in the fourth quarter in select markets.
An executive at an eastern European operator said he would start sales of the Lumia 920 in the second half of November, adding larger countries would receive the model earlier that month.
A source at a Nordic operator said sales at his carrier would start in mid-to-late November.
A Nokia spokesman declined to comment on Friday on when sales would start.
Rival Apple is expected to launch a new iPhone along with pricing and availability details next week.
Earlier this week, Nokia cut about 15 percent off the price of its midrange Lumia 800 Windows Phone and made smaller price reductions on its other Windows models.
Nokia says the price cuts are part of its usual business.
