Compliance considerations

French mobile networks block marketing SMS traffic between 10pm and 8am, on Sundays, and on French public holidays. If messages are sent during these restricted times, they will be queued and sent the following day.

Bouygues Telecom does not support Unicode body encoding for application-to-person (A2P) SMS. All Unicode characters will therefore be replaced with GSM characters to ensure delivery.

Twilio strongly encourages customers to review proposed use cases with qualified legal counsel to make sure that they comply with all applicable laws. The following are some general best practices:

  1. Get opt-in consent from each end-user before sending any communication to them, particularly for marketing or other non-essential communications.
  2. Only communicate during an end-user’s daytime hours unless it is urgent.
  3. SMS campaigns should support HELP/STOP messages, and similar messages, in the end-user’s local language.
  4. Do not contact end-users on do-not-call or do-not-disturb registries.

French domestic Long Codes can only be used for person-to-person (P2P) messages. Using it for any high volume messaging, or even for application-to-person (A2P) messages, will result in delivery failure and the domestic Long Code being blocked.

French mobile operators do not support message delivery via international Numeric Sender ID. Submission by International Long Codes will be attempted on a best-effort basis. The Long Code will be overwritten with a generic Alphanumeric Sender ID or Short Code outside the Twilio platform.
