Best practices

The Turkish carriers are filtering traffic with numeric, shortcode and unregistered Sender IDs. Alpha Sender ID pre-registration is mandatory and so unregistered Sender IDs may be blocked by the carriers. P2P, gambling, political or religious related traffic is not permitted.

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:

  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.
