The company is headquartered in the capital city Sofia and employs around 5,900 people, owning a mature distribution network with around 230 branded retail outlets and alternative sale points.

The company has gone through various stages of operation – from the long period of state-owned structure to the privatization procedure in 2004, when the Bulgarian government sold 65% of the share capital.

In late 2012, VTB Capital, the investment arm of Russia's second-largest bank, led a consortium (Viva Telecom Bulgaria EAD) to buy a controlling stake in BTC.

In November 2012, Viva Telecom Bulgaria EAD acquired a 93.99 percent stake in the Bulgarian Telecommunications Company.

The acquisition was finally canceled by the Belgian investor in July 2015 following numerous embezzlements discovered by him, during the takeover of the Bulgarian group.
