Sending SMS to landline numbers	You cannot send SMS to a landline destination number: the Twilio REST API will throw a 400 response with error code 21614, the message will not appear in the logs, and the account will not be charged.
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: Get opt-in consent from each end-user before sending any communication to them, particularly for marketing or other non-essential communications. Only communicate during an end-user’s daytime hours unless it is urgent. SMS campaigns should support HELP/STOP messages, and similar messages, in the end-user’s local language. Do not contact end-users on do-not-call or do-not-disturb registries.
