Telecommunications in Mongolia face unique challenges. As the least densely populated country in the world, with a significant portion of the population living a nomadic lifestyle, it has been difficult for many traditional information and communication technology (ICT) companies to make headway into Mongolian society. With almost half the population clustered in the capital of Ulaanbaatar, most landline technologies are deployed there. Wireless technologies have had greater success in rural areas.
The telecommunications in Russia has undergone significant changes since the 1980s, radio was a major new technology in the 1920s, when the Communists had recently come to power. Soviet authorities realized that the "ham" operator was highly individualistic and encouraged private initiative – too much so for the totalitarian regime. Criminal penalties were imposed but the working solution was to avoid broadcasting over the air. Instead radio programs were transmitted by copper wire, using a hub and spoke system, to loudspeakers in approved listening stations, such as the "Red" corner of a factory. This resulted in thousands of companies licensed to offer communication services today. Due to the enormous size of the country Russia today, the country leads in the number of TV broadcast stations and repeaters. The foundation for liberalization of broadcasting was laid by the decree signed by the President of the USSR in 1990. Telecommunication is mainly regulated through the Federal Law "On Communications" and the Federal Law "On Mass Media"

3G mobile telephony was relatively slow to be adopted globally. In some instances, 3G networks do not use the same radio frequencies as 2G so mobile operators must build entirely new networks and license entirely new frequencies, especially so to achieve high data transmission rates.

Due to these issues and difficulties with deployment, many carriers delayed acquisition of these updated capabilities.
