Nepal Telecom, a telecommunication service provider, owned by the Government of Nepal, is a popular institution. It was established in 2032 B.S. with an aim to provide telecommunication services to the people of Nepal through the use of telephone and other means of communication. But today, this organization has moved in the path of progress in such a way that it has been able to provide different types of communication services

to the people, including national and international voice calls, video calls, SMS, MMS, mobile internet, ADSL internet, wireless internet etc.

And now, Nepal Telecom has decided to launch its very own social networking site. It has planned to bring its own social networking Nepal Telecom Logosite in order to help the people, especially Nepalese people, to stay connected everytime. It is currently testing the new social networking site internally.

Anoop Ranja, Managing Director of Nepal Telecom, stated, “The social site will have all facilities like those of Facebook. Not only that much, it will also have Skype, group message and Viber services.” He also added that the preparations to launch the new social networking site were at the final stage.

However, Nepal Telecom hasn’t named its site yet. Although the social networking site was previously named as ‘Chautari’, Nepal Telecom decided to find some other name which could help in the promotion of its brand.

Guna Keshari Pradha, Spokesperson of Nepal Telecom, said, “The social networking site will have more facilities than those of Facebook and this site will be very appropriate as well as useful for the Nepalese.”

After the launching of the new social networking site, Nepalese users will be able to use it for a number of purposes including making new friends, chatting, creating group messages, making Internet Protocol (IP) calls, uploading and sharing photos and videos, writing status messages and comments etc.

The current target of the new social networking site is to benefit one million people. This target will later be increased to ten million people. Nepal Telecom has invested about NRs. 900 million so as to construct the new social networking site.

This act of Nepal Telecom has surely brought enthusiasm, curiosity and joy among the social network lovers. However, social network lovers will have to wait for some time in order to get benefitted from this site.
