Networks in Saudi Arabia have implemented very complex spam filters that in most cases block even legitimate application to person traffic. Therefore, cheap signalling/roaming links do not deliver well especially for high value content such as password delivery or alerts, let alone marketing bulk traffic. Additionally all the routes in Saudi are unstable due local issues so relying on one route is not possible.
Nexmo has therefore created a dynamic routing in Saudi Arabia, which combines several routes and chooses the best one to ensure your message is delivered.
Please be informed that to reduce spam the Communications and Information Technology Commission (CITC) require senderID and separately URL registration, to which all Saudi operators are obliged to comply.
For bulk message (Ads and promotions, anything non-transactional) senderID must include the suffix "-AD" or " AD". So promotional content has to be sent with "SID-AD" (length = 11 digits) format i.e. Nexmo-AD.
Promotional / marketing contents are allowed only from 7 am to 10 pm Saudi Arabia time zone (GMT +03:00).
If you have transactional messages which are either user-generated or expected, you can register an Alpha SenderID to bypass the traffic filters and NDNC registry.
