Sending SMS to landline numbers

Best practices

All traffic will be overwritten to numeric senderID in order to ensure delivery.

You may use a global SMS-capable number to reach mobile phones in Syria.

The current political situation in Syria has left the telecommunications infrastructure in extreme disrepair. Message delivery rates in Syria are poor.

P2P traffic is not permitted on our routes to Syria.

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, 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.
