Blackberry company claims to have sold 1 million Z10 mobile phones
In better than expected results the company said it made profits of $98m (£65m) in the quarter, after posting a big loss for the same period last year.
The Z10 handset is seen as crucial to the future of Blackberry, which has struggled to keep up with new Apple and Android phones.
It has been on sale for a month in the UK, Canada and other markets.
It went on sale with little fanfare a week ago in the United States, Blackberry's most important market.Blackberry reports 1m Z10 sales
The figures do not include US sales.
Blackberry was previously called Research In Motion, but changed its name last year.
Analysts greeted the results cautiously, saying that it was too early to judge the success of the Z10 and its sister device the Q10.
Earlier in the week, Blackberry shares were hit when two major US brokerages expressed disappointment with the US launch of the Z10.
In a note to its clients Citigroup described the launch as "a big disappointment".
The Blackberry results also showed the company lost three million users over the year. Its handsets are now used by 76 million people, down from 79 million 12 months ago.
In total, Blackberry said it shipped a total of around six million handsets in the three months to early March.
