(Telecompaper) The Dutch mobile sector last year again experienced a decline in revenues, down 4.4 percent from 2016, according to Telecompaper's latest Dutch Mobile Operators report. The combined revenue from mobile services at KPN, Vodafone, T-Mobile and Tele2 amounted to EUR 4.5 billion in 2017. Revenues have been steadily declining in recent years, falling 4.0 percent in 2016 and down 3.3 percent in 2015. The drop accelerated in 2017, but has not yet equaled the 7.5 percent fall recorded in 2014.
