Bulgarian Telecommunications Company (BTC) is a previously state-owned telecommunications company providing mobile services under the Vivacom brand. In June 2004 the Bulgarian government sold 65% of BTC capital to Viva Ventures Holding, a subsidiary of the US private equity fund Advent International. In January 2005 the Bulgarian state launched public offering of the remaining shares and offered 34.78 percent of the company's capital on the Bulgarian Stock Exchange. The company rebranded to Vivacom in 2009 following a merger between vivatel and its parent company BTC. The company was sold in 2016 to Russian businessman Spaz Roussef.
Vivacom provides 2G GSM services over the 900 MHz band and in November 2005 the company launched its 3G UMTS mobile services over the B1 (2100 MHz) band, and in June 2010 extended coverage through a B8 (900 MHz) 3G rollout. 4G LTE was launched in May 2016 over the B3 (1800 MHz) band, which has been upgraded following further spectrum acquisitions to provide data rates in excess of 100 Mbps. In April 2018 the company launched LTE-A with 2C aggregation of its existing B3 (1800 MHz) service with a new B1 (2100 MHz) network, and advertising peak DL rates of 150 Mbps.
Vivacom and Nokia deployed a LoRa IoT network in November 2017.
