A message that works in Norway may face different technical and legal conditions in another country. Check the market before assuming that the sender, content and routing will work in the same way.
Number format and destination
Normalise numbers with the correct country code and test a representative sample. Pricing and available routing differ by destination, so check the current setup before a larger campaign.
Local rules and sender requirements
Consent, opt-out, sender registration and permitted content may vary. Use the delivery guide as a starting point and obtain appropriate local advice where the rules are critical.
Language, time zone and support
Write in a language the recipient expects and avoid expressions that translate poorly. Schedule according to local time, test links from the market, and explain how recipients can get help or opt out.
Create a checklist for each country
Record number format, sender requirements, permitted content, local time, opt-out, pricing basis and who can provide local guidance. Do not reuse an old country assessment uncritically; operator requirements and rules can change. Confirm important conditions before entering new markets or increasing volume.
Test the actual setup
Send to your own or approved test recipients in the relevant market. Check how the sender appears, whether the link opens and how technical responses are handled. A successful test does not guarantee every message, but it can reveal errors before they affect many recipients.
A relevant next step
Choose the right working method
Compare the portal, API and tools before deciding how SMS should fit in.
