Technical Guidelines

Two-Way SMS Support

In Samoa, two-way SMS is not supported. Users cannot reply to SMS messages, so businesses should adjust their communication strategies accordingly. Consider alternative channels if interaction is required.

Number Portability

Number portability, which allows users to switch providers without changing numbers, is not available in Samoa. This simplifies message routing but restricts users from retaining their numbers across networks.

Concatenated Message Support

Samoa does not support concatenated SMS. Messages exceeding the standard length will not be split and reassembled, risking delivery failure. Keep messages concise.

Message Length

While there are no specific message length restrictions, adhere to the standard SMS character limit (160 characters for GSM-encoded messages) to avoid issues.

MMS Support

Multimedia Messaging Service (MMS) is converted to SMS with an embedded URL. Recipients receive a link to view content instead of direct multimedia.

Sending SMS to Landline Numbers

You cannot send SMS to landline numbers in Samoa. Attempts will result in a 400 error with code 21614, and the message will not be logged or charged.

Compliance Considerations

Compliance is crucial for SMS campaigns, especially internationally. Consult legal counsel to ensure adherence to local laws. Here are some best practices for SMS compliance in Samoa:

  • Opt-In Consent: Obtain explicit opt-in consent before sending communications, especially for marketing.
  • Respect Local Time Zones: Send messages during local daytime hours unless urgent.
  • Support HELP/STOP Messages: Enable users to manage preferences with HELP/STOP messages in the local language.
  • Do-Not-Call Registries: Avoid contacting users on do-not-call or do-not-disturb lists.
