Prohibited Content: Gambling and lottery-related content is strictly prohibited by mobile operators in Norway. Ensure your SMS campaigns do not contain such content to avoid penalties.
-
Opt-In Consent: Always obtain opt-in consent from end-users before sending them any communication, especially for marketing or non-essential messages. This is crucial for compliance with local regulations.
-
Timing of Messages: Only send messages during the end-user’s daytime hours unless it is urgent. Avoid sending messages late at night or early in the morning.

Support for HELP/STOP Messages: SMS campaigns must support commands like HELP and STOP, and these should be available in the recipient's local language.
-
Do-Not-Disturb Registries: Ensure that you do not contact users on do-not-call or do-not-disturb registries. Violating these lists can result in legal consequences.
