​​10% of entire Sweden (around mayor cites, Stockholm, Gothenburg, Malmö, Lund ... and Veberöd has 100% coverage.
​​100% coverage of entire Sweden, They are activily rolling it out and plan to have full coverage by the end of 2019!
​​NB-IOT is officially by 3GPP only an IP-network (NO DNS support!)
​​
​​Telia does allow you access to the entire WWW [in other countries by other operators you can only send via IP to the operators own serves, and fetch the data via API's into your portal ...
