Key Features of SMS in Saint Lucia

Two-Way SMS Support

Two-way SMS is not supported in Saint Lucia. You can send messages, but recipients cannot reply directly via SMS.

Number Portability

Saint Lucia allows number portability, enabling users to keep their mobile numbers when changing service providers. This ensures continuous communication with users, regardless of carrier changes.

Concatenated Message Support

Saint Lucia supports concatenated SMS, allowing messages exceeding the standard character limit to be split and reassembled. Note that this feature may vary based on sender ID types and character encoding.

Message Length

The character limit for a single SMS depends on the encoding used. Exceeding this limit will split the message into multiple segments. Monitor character count to prevent unintended splits.

MMS Support

Multimedia Messaging Service (MMS) is not supported. Instead, MMS messages are converted to SMS with an embedded URL, sending media content as a link.

Sending SMS to landlines in Saint Lucia is not supported. Attempts will result in a 400 error code with error code 21614, and the message will not be delivered or charged.

Compliance Considerations

Ensure your SMS campaigns comply with local laws and best practices:

  • Obtain Opt-In Consent: Secure explicit consent from recipients before sending messages, especially for marketing.
  • Respect Local Time Zones: Send messages during local daytime hours unless urgent.
  • Support HELP/STOP Commands: Allow recipients to manage preferences with commands like "HELP" or "STOP."
  • Do-Not-Call Registries: Avoid contacting individuals on do-not-call lists.

For more compliance details, consult official guidelines.
