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.

Best practices

Delivery of messages submitted with numeric sender ID is on best effort and will be overwritten with either random numeric or alphanumeric sender ID. Pre-registration of alphanumeric sender ID is required.

Twilio strongly encourages customers to review proposed use cases with qualified legal counsel to ensure they comply with all applicable laws. The following are some general best practices. You can also read more at Indonesian Telecommunication Regulatory Authority. (http://brti.or.id/)

  1. Get opt-in consent from each end user before sending any communication to them, particular 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.
