Yettel Serbia, known as Telenor Serbia until 2022, is a telecommunications provider offering mobile, fixed, internet and IPTV services in Serbia. The company is owned by PPF, a Czech investment group, and is headquartered in Belgrade. Yettel Serbia was originally launched in 1994 as Mobtel Srbija, a joint venture between Moscow-based BK Trade and the government-owned PTT. In 2005, the company was sold to a consortium of Austrian investors and renamed Mobi 63.
In 2006, a majority stake in Mobi 63 was sold to the Norwegian company Telenor. The company underwent further transformations, including acquiring a landline operating licence in 2010, establishing Telenor banka in 2013, and selling 85% of its shares to the Bulgarian investment fund River Styxx Capital in 2017. In 2018, Telenor sold its business in Southeast Europe, including Telenor Serbia, to the investment fund PPF. The company continued to operate under the Telenor brand until early 2022, when it was rebranded as Yettel.
