Vietnam had 131.6 million mobile phone and 9.5 million landline subscribers by the end of 2012, according to the Vietnam's Information and Communication Information (ICT) White Book 2013.

Released by the Vietnam's Ministry of Information and Communication (MIC) on Monday, the publication showed that although the development of telephone and internet subscribers slowed down due to market saturation, the number of mobile and internet users posted growth rates of 3.42 percent and 2.46 percent over 2011, respectively.

Notably, the number of fixed broadband internet subscribers increased 24.74 percent to nearly 4.8 million subscribers in 2012 while the number of 3G subscribers dropped from 16 million to 15.7 million.

The number of pay TV subscribers has almost doubled over 2011, bringing the total revenue of pay TV to 200 million U.S. dollars.

In 2012, the country's ICT sector earned 25.5 billion U.S. dollars, an increase of 86.3 percent year-on-year, while postal services pocketed nearly 274 million U.S. dollars, said the publication.

The Vietnam's ICT White Book provides information and data in the fields of ICT infrastructure, information technology, post and telecommunications, ICT human resources and information security.
