Jean-Pierre Vandromme said GT would offer long-distance services within the country using the calling code 51, and overseas calls with the code 56.
GT, which will join Russian companies Rostelecom and MTT on the long-distance calls market, plans to gain a 20% market share by 2010, and earn $1 billion from its services, Vandromme said. The country's total long-distance calls market will be worth $4.8 billion by that time, compared to $2.8 billion last year, he added.
The GT chief executive said the company's tariffs for national calls would be 10% lower on average than Rostelecom's, and 10-65% lower for international calls.
He also said a special tariff of $20 a month could be established for unlimited calls, and that company would set up a network of more than 4,000 agents and about 30,000 distribution offices across Russia to sell its services to customers.
GT provides integrated telecommunications and Internet services in Russia's main cities and in other former Soviet nations. Its major shareholders are Alfa Group's telecoms arm Altimo (29%), Norway's Telenor (20%), and Rostelecom (11%).
