(Telecompaper) The Dutch mobile service market contracted 6.6 percent in 2014 to EUR 5.0 billion in revenues, according to Telecompaper's latest market monitor. The drop in service revenue slowed from 7.1 percent in 2013, but was still due in part to regulatory factors. Lower termination and roaming rates were responsible for about a third of the revenue lost last year; without the regulatory impact, revenues would have fallen only 4.6 percent. The rest of the drop in revenue in 2014 was due to tough competition, lower out-of-bundle revenues and changes in customer behaviour, as the growing use of messaging and VoIP apps led to a continued decline in voice and SMS revenues. Data revenues showed only modest growth, despite a near doubling in mobile data traffic, driven by the growing number of 4G users. For 2015, Telecompaper expects a smaller decline in service revenue, of around 4.4 percent.
