(Telecompaper) All three of Italy's main mobile network operators felt the disruptive effects of low-cost challenger Iliad in the third quarter, with Wind Tre and Vodafone hit hardest, according to new data from Telecompaper. Total mobile service revenues in Italy fell by 3.0 percent year-on-year to EUR 3.2 billion in the third quarter of 2018, led by steep declines at Wind Tre and Vodafone, in spite of Iliad's initial EUR 46 million contribution in the July to September period.
