(QHA) -

Ukrainian mobile operator Kyivsta, the largest mobile phone operator in Ukraine, announced that it faces problems working on the basis of Ukrainian legislation in the Crimea region.

The use of the Ukrainian currency, which is the only legal payment means according to Ukrainian law, has become impossible in the region. The operator faces difficulties paying for power and other resources, meaning its base stations and access nodes can't operate in the region.

The situation has resulted in a decline in services quality in Crimea, Kyivstar said.

 “The circumstances could not be eliminated by the company’s own efforts. However, we are doing our best to maintain the high quality coverage on our part and apologizing to subscribers for the inconveniences.”- Kyivstar noted.

Crimea was annexed by Russia in March 2014. Russian ruble became the only state currency in the region.
