 Service-Telecom entered the market in 2015. The company installed radio masts and cell phone towers on roads in the Moscow region the same year.

 In 2017, Service-Telecom acquired a majority stake (100%) in Link Development, the first tower company in Russia. After the deal was signed, Service-Telecom owned more than 1000 towers. Mikhail Alexeev, a partner of AC&M Consulting, estimated the value of the transaction at between 600 million and 1 billion rubles. Yuri Brukvin, the Director General of the Rostelecom analytical agency, described Link Development as a highly marginal business and estimated its value at 3 billion rubles minus debt, amounting to about 400 million rubles.
 In 2017, the Service-Telecom Group of Companies was created to provide a platform for the construction of wireless communication infrastructure in Russia.

The deal amounted to 70,65 billion rubles on a debt-free basis, together with deferred payments. The deal included a 100% stock sale of the National Tower Company (NTC), which owned about 15400 mobile cell towers in Russia. In April 2022, the deal was recognized as the "Telecom Deal of the Year" by the Russian M&A. It was the first major deal in the history of the Russian telecom market: the purchase of the cellular MNO's towers led to an overall change in the market.
 In December 2022, Service-Telecom acquired two regional tower companies - «Opora Telecom» and «Dacha na Svyazy», which together own 500 towers in the Voronezh, Penza, Leningrad, and Belgorod regions, and in St. Petersburg. The deal allowed Service-Telecom to increase its portfolio to 19 100 sites.

Owning about 18500 facilities, the company operates throughout Russia, with its headquarters being located in Moscow and Saint Petersburg. Service-Telecom is included in the government's list of systemically important organizations.
 The key metric for valuing mobile infrastructure companies is the average number of tenants or operators sharing cell tower infrastructure. The rate depends on the average number of tenants per tower (tenancy ratio, TR). According to AC&M Consulting, as of February 2022, a standard TR for telecom operators is 1,1-1,2. For Service-Telecom, it is 1,9; in some regions, TR reaches 2,5-3,5.
