• Nepal Telecom - Brief Introduction In Nepal,
  operating any form of telecommunication service
  dates back to 94 years in B.S. 1970. But formally
  telecom service was provided mainly after the
  establishment of MOHAN AKASHWANI in B.S.
  2005.Later as per the plan formulated in First
  National Five year plan (2012-2017)
  Telecommunication Department was established in
  B.S.2016. To modernize the telecommunications
  services and to expand the services, during third
  five-year plan (2023-2028), Telecommunication
  Department was converted into Telecommunications
  Development Board in B.S.2026. After the
  enactment of Communications Corporation Act 2028,
  it was formally established as fully owned
  Government Corporation called Nepal
  Telecommunications Corporation in B.S. 2032 for
  the purpose of providing telecommunications
  services to Nepalese People. After serving the
  nation for 29 years with great pride and a sense
  of accomplishment, Nepal Telecommunication
  Corporation was transformed into Nepal
  Doorsanchar Company Limited from Baisakh 1, 2061.
  Nepal Doorsanchar company Limited is a company
  registered under the companies Act 2053. However
  the company is known to the general public by the
  brand name Nepal Telecom as registered
  trademark.Nepal Telecom has always put its
  endeavors in providing its valued customers a
  quality service since its inception. To achieve
  this goal, technologies best meeting the interest
  of its customers has always been selected. The
  nationwide reach of the organization, from urban
  areas to the economically non- viable most remote
  locations, is the result of all these efforts
  that makes this organization different from
  others. Definitely Nepal Telecom's widespread
  reach will assist in the socio-economic
  development of the urban as well as rural areas,
  as telecommunications is one of the most
  important infrastructures required for
  development. Accordingly in the era of
  globalization, it is felt that milestones and
  achievements of the past are not adequate enough
  to catch up with the global trend in the
  development of telecommunication sector and the
  growth of telecommunication services in the
  country will be guided by Technology, Declining
  equipment prices, market growth due to increase
  in standard of life and finally by healthy
  competition.Converting NT from government owned
  Monopoly Company to private owned, business
  oriented, customer focused company in a
  competitive environment, Nepal Telecom invites
  its all-probable shareholders in the sacred work
  of nation building.
