Picture-sharing pushes mobile uploads to exceed downloads Speaking at the Telegraph's Festival of Business, Olaf Swantee, chief executive of EE, said events like Glastonbury and the London Marathon had driven a huge surge in photograph and video uploads. He said Andy Murray's win at Wimbledon had caused a 20pc uptick in mobile use. But Mr Swantee said that the telecoms must be careful not to forget the original purpose of mobiles - to make calls. He admitted that an "accepted industry standard" of one dropped call in every hundred had been allowed to prevail, and said it was "not good enough." He said EE was working hard to improve network coverage across the country and on motorways and railway lines. He said the UK had "big challenges" because of its hills, trees and villages set in valleys.
