In December 2014, in a premium Digital Fuel Monitor research note titled “Mobile consolidation on Denmark’s doorstep” (link) we took a close look at the Danish mobile market ahead of the planned merger of Telenor (no.2) and TeliaSonera (no.3). On the 8th of April 2015 the European Commission opened an in-depth investigation into the proposed merger. Digital Fuel Monitor documented the Danish smartphone mobile internet access prices for the first time in January 2014 (Rewheel has been monitoring Danish prices since December 2012). During the course of 2014, while the merger was in the making and after December 2014 that the merger was publicly announced the four Danish mobile operators launched new tariff plans and made adjustments to their existing plans both in their main and discount brands.
