Yettel Bulgaria, part of the PPF Telecom group, is a telecommunications company that connects over 3 million customers to people, devices and businesses. The company is formerly known as Telenor Bulgaria until March 2022, when the new Yettel brand was introduced.

Over its two-decade presence in Bulgaria, the company has established itself as a pioneer in wireless networks. It introduced Bulgaria's first commercial 4G network in 2015, followed by the debut of the first VoLTE service in 2018, and initiated the country's first test of fifth-generation networks, laying the groundwork for 5G development.
