Also NB-IOT is being introduced by European operators quite fast. Luckily here in the Netherlands we are one of the first.
Both T-Mobile and Vodafone plan to have NB-IOT up and running in 2017 in the Netherlands. I believe the Netherlands is used by the operators as ' trial country' because of the relative small geographical size, high population, strong economy and good tech sector with large business but also a lot of start-ups.
Aside from this The Netherlands was the first country where an operator (KPN) introduced a nationwide LORA network so the other operators want to keep up with the competition. Interesting times ahead!
