The peak of Mt. Everest became a wi-fi hot spot when 3G plan was successfully launched in Nepal by a Sweden-based carrier. The chief executive of Ncell, a subsidiary of TeliaSonera, said the highest video call ever was made from the Mount Everest base camp Friday. Now that Nepal has the beginnings of a 3G network, climbers can go online at the peak of the world's highest possible peak and one of one of the most backward countries on Earth will get a taste of modern technologies.
