Norway is an important and very developed destination for SMS delivery. Carriers are actively blocking cheap SS7 routes. Nexmo has high quality direct routes to all networks in Norway and we use them as part of our adaptive routing to maximise delivery rates.
There are no known restrictions on Sender ID to Norway.
There are no additional content restrictions beyond those in our Acceptable Use Policy
Other features/restrictions of note:
Handset delivery receipts are fully supported.
Norway SMS numbers must support STOP and STOPP responses. Nexmo manages the opt out process per the carriers requirement on behalf of our customers.
