Compliance considerations |
Saudi Arabian networks have implemented strong filtering that blocks messages coming from Numeric Sender IDs, messages that contain objectionable content, and messages that contain URLs. Messages sent with identical content to a recent message will also be blocked. To avoid the possibility of messages to users in Saudi Arabia being blocked, be sure to pre-register your Alphanumeric Sender IDs. Promotional messages should only be sent between 08:00am and 10:00pm local time. Messages sent to mobile numbers registered in the DND list will be filtered. Twilio is unable to register Sender IDs on behalf of domestic brands based in Saudi Arabia or Qatar because of a new regulation that prohibits the re-selling of domestic traffic.
