Operating profit jumped by 3.9 percent to 631.1 million francs from the previous year – the highest level in the company’s history.
The biggest growth driver was the mobile phone segment, the Zurich-based company reported on Friday.
Sales rose 4.2 percent to 2.07 billion francs, the telecoms provider said in a statement.
In the mobile phone business sales rose 2.9 percent to 1.3 billion francs.
At the end of December, 1.18 million people had a mobile contract with Sunrise – up 6.9 percent on 2011.
Growth was even higher in the fixed-line segment, where sales were up 8.3 percent at 579.7 million.
By contrast, turnover in the internet business rose a modest 1.1 percent to 178.2 million.
Almost a year after launching its TV business, Sunrise released figures for the fist time.
These showed that by the end of December the company had 38,000 customers, with over 8,000 customers having ordered Sunrise TV.
Sunrise CEO Libor Voncina said the result was remarkable given the tough competition in the Swiss market.
The 49 year old has been at the helm of the company for just two months ago, after replacing Oliver Steil who left the company unexpectedly, the Swiss news agency SDA reported.
