During the third quarter, we were actively involved in the construction of our mobile networks in selected regions, primarily where Rostelecom already has mobile operations or uses frequency licences obtained through the acquisition of Sky Link, which was completed at the end of July. Following the test launch of our first 3G network in the Irkutsk region, the mobile data traffic in the region increased by 1.5 times. This clearly indicates that we are moving in the right direction to meet our clients’ needs. Our successful participation in the LTE licence tender process was also among the key developments of the third quarter“.

This was the first time the united Rostelecom has issued bonds since the start of the reorganisation process in 2011.
