Omnitel said in a press release that Stromberg, who has been with TeliaSonera for more than 20 years, was appointed as the Lithuanian company's president on Friday.
Stromberg has good experience in achieving results in difficult market conditions. As the CEO of TeliaSonera's fixed-line communications company in Denmark in 2009-2012, he turned the loss-making company into a profitable one, according to the press release.
"Lithuania's mobile communications market is currently going through a challenging transition period. We are planning to achieve market leadership and increase profitability," Kennet Radne, the head of TeliaSonera's Baltic mobile communications unit, said in a press release.
"Omnitel will introduce a new business model that will increase data transmission and slow down the decline in voice services. In an effort to meet users' needs for mobile Internet, we will continue the modernization of the network and will further expand the 4G LTE network coverage and increase its capacity," he said.
Zabulis had been at the helm of Omnitel since October 2000.
