Mobiltel, the Bulgarian unit of Telekom Austria, is the largest mobile phone operator in Bulgaria. At the end of June it had almost 5.3 million customers, and its mobile market share stood at 49.3%. The telecom has entered the fixed market in recent years. In 2010 the company acquired two major Internet operators in Bulgaria. Thus the company strengthened its position on fixed market as well. Mobiltel was the first Bulgarian operator to offer EDGE, UMTS, HSDPA and HSPA+ services to its clients. In August it received regulatory permission to test the country`s first 4G wireless network.
