Global mobile subscriptions saw a 9% rise in 2012 to 6.3 billion year-on-year, boosted by the growth in expanding markets in India and China, according to a new report from Ericsson.

During the fourth quarter of 2012 (4Q12), global mobile penetration reached 89% while the actual number of subscribers reached 4.4 billion, as many users have several subscriptions.

China accounted for 22% of net additions or about 30 million subscriptions, followed by India, Bangladesh, Indonesia and Nigeria.

Mobile subscriptions rose about 9% year-on-year and 2% quarter-on-quarter.

According to the report, mobile broadband subscriptions during the quarter rose 50% to 1.5 billion, compared to the corresponding quarter in 2012.

In 2012, smartphones sales contributed 40% of the sales of all mobile phones, compared to around 30% for 2011.
