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 does 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.
PUSHTech has therefore created a dynamic routing in Saudi Arabia, which combines several routes and chooses the best one to ensure your message is delivered. This does however mean that DLRs are inconsistent and are therefore not an accurate measure of delivery in Saudi Arabia. No religious, political or adult content is allowed. Numeric Senders of more than 11 digits will be blocked.
SenderIDs will vary but generally:
Al Jawal (42001) will support alpha senders only, all numeric senders will be overwritten with NXSMS
Mobility (42003) will support dynamic sender
Zain (42004) will support dynamic sender
