(Telecompaper) Independent MVNOs are approaching 20 percent of the Dutch mobile market, according to the latest report from Telecompaper. They counted 4.0 million customers at the end of March, and increased their market share to 19.7 percent of total Dutch Sims, from 19.2 percent six months earlier. Other 'virtual' brands, such as the second brands or co-brands run by the mobile operators, had around 4.6 million customers. Together the two had 41.8 percent of DUtch mobile customers at the end of March. Virtual operators also active in the fixed market, such as Ziggo Mobiel and Tele2, and in the 'no-frills', low-cost segment, such as Hollandsnieuwe, Simpel and Youfone, were the main ones growing in the period researched. The no-frills segment remains the largest in the Dutch VO market, accounting for slightly more than a third of customers, while the fixed segment has a 12 percent market share. While virtual operators slightly expanded their market share, more virtual players exited the market than entered it in the six months since Telecompaper's last report on Dutch MVNOs. After counting three new brands and five exits in the period, the total number of active mobile virtual operators in the Netherlands fell to 65 at the end of March 2015.
