Income from data services is expected to be the key growth driver for Malaysia's telecom operators this year as the country's broadband usage remained low at 55 percent of the population at end-2010.

"The driver of revenue growth for the foreseeable future is from the increasing demand for wireless broadband, internet access and other non-voice services," said Maxis, Malaysia's second biggest mobile phone operator by market capitalisation.

Maxis posted a net profit of 610 million ringgit ($199.8 million) for October-December, up from 503 million ringgit a year earlier.

Net profit for the full year was 2.3 billion.

Regional telecommunication companies are facing a rapid decline in traditional fixed-line phone services and are having to spend more to win back customers.

Maxis' mobile subscriptions rose by 14 percent to 13.9 million in 2010, with prepaid and wireless broadband up by 1.4 million and 330,000 subscriptions respectively.

The company said it would pay a final dividend of eight sen per share.

Maxis said it would continue to invest in its networks to meet customers' demand for smart data devices this year.

"The group will also continue its focus on cost management and operational efficiency initiatives to maintain operating margins," it said in a statement.

Maxis shares have risen by about two percent since the start of the year but lagged behind rival DiGi's eight percent gain.
