— This is the script of CNBC's news report for China's CCTV on February 25, Tuesday.
Welcome to the CNBC Business Daily.
Whatsapp is set to take on Skype and Viber.
Facebook's Mark Zuckerberg has announced that his latest acquisition will offer free voice calls in the second quarter of this year.
Speaking at the Mobile World Congress in Barcelona, Zuckerberg defended the 19 billion dollar deal, and said that the addition of voice calls could increase the company's user base from to 450 million to one billion.
CNBC's Jon Fortt has all the details:
Mark Zuckerberg was the big headliner on this first day of the Mobile World Congress in Barcelona.
He talked about the Whatsapp acquisition and he talked about his desire to connect more people, particularly in emerging markets, who either can't afford wireless connections, or aren't sure why they should have one.
But on the Whatsapp acquisition in particular, he was pressed on whether it was really worth $16-19 billion dollars.
Take a listen to what he had to say:
"I could be wrong. I mean, there is some chance that this is the one service that gets to a billion people and ends up being not that valuable. I don't think I am. I thin you can look at other messaging apps that are out there - whether its KaKao, or Line or Wechat, that are already monetizing at a level of $2-3 per person with pretty early efforts and I think that shows that if we can do a pretty good job of helping Whatsapp to grow, then this is just going to be a huge business."
Lots of other news out of the conference so far, notably, Nokia coming up with a lower end phone that runs Android - the X Phone.
It'll be interesting to see if Microsoft retains that once it acquires the company in just a few days or weeks, not sure how new CEO Satya Nadella will feel about that.
There were announcements from the likes of HP and Lenovo, convertible tablets.
Huawei's come up with a smart watch, and there's more to come.
Lots of attention on emerging markets, that's seen as the new growth area.
The question is, whether payments or some new technology will be a key way to monetize those new subscribers.
