Ljubljana, Slovenia

Si.mobil is Slovenia’s first privately owned mobile operator, offering high-quality, low price services and holding a 30% market share. Since opening in 1999, the company has maintained a number two position, aiming at becoming a market leader. Si.mobil is owned by the Telekom Austria Group, which is the leading telecommunication company in Central and Eastern Europe, operating in 8 markets and serving 23 million customers.

Si.mobil continues to alter the state of mobile technology in Slovenia and the region. The company was the first mobile operator to market text messaging, the first one to provide fast data rates over EDGE technology, and also the first to offer services over an LTE network. At the end of 2014, Si.mobil brought LTE technology to 75% of the Slovenian population.

The company employed 418 people in 2013, who provided seamless mobile services to 679,200 customers, a 2.5% growth in comparison to the previous year. At the end of Q3 2014 the number of customers increased to 683.200.

Si.mobil’s commitment to professional and personal life balance brought the company the Family Friendly Enterprise certificate, and an excellent reputation amongst job and mobile company seekers, alike.

In 2013, after a major workplace redesign project managed by Kragelj has been completed, receiving high praise from employees, Si.mobil was awarded the Best Employer of the Year award among large enterprises. The company also won an internationally acclaimed Superbrands award multiple times.
