A Nepali telecom firm plans to expand its mobile phone services to the top of Mount Everest, benefiting climbers on the world's highest mountain, a company official said last week, the Age reports.

Hundreds of climbers, who go to the 8850-metre Mount Everest every year, depend on expensive satellite phones to speak with their families as the remote Himalayan region does not have communication facilities.

"We are going to set up mobile towers in Thakdin, Manjo, Pheriche and Gorak Shep, which will bring the summit of Mount Everest within the network coverage," Anoop Ranjan Bhattarai, director of the satellite service wing of Nepal Telecom, said.

Gorak Shep, in the Solukhumbhu region, is located near the base camp of Mount Everest. "A mobile tower at Gorak Shep will provide connectivity to climbers at the top," Bhattarai said, adding the firm hoped to finish the work by mid-June.

Annual monsoon rains normally start in mid-June after which transportation of equipment along the hilly trails becomes difficult.
