In December 2024, Ukraine's three largest mobile operators introduced VoLTE and VoWiFi services on their networks, which function even in areas with weak signals, according to the National Commission for the State Regulation of Electronic Communications, Radiofrequency Spectrum and the Provision of Postal Services (NCEC). “This significantly improves voice quality and keeps subscribers connected even in areas with poor signals," NCEC stated on its official Facebook page on Tuesday.
