Saudi Arabia: SMS Features and Restrictions

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. 

Nexmo has therefore partnered with suppliers that can pre-register against, and deliver the SMSs without problem. Please ensure you are not using Numeric or Generic Alpha SIDs and that you pre-register your Alpha SID and content with us. 

Please be informed that to reduce spam the Communications and Information Technology Commission (CITC) require sender ID and separately URL registration, to which all Saudi operators are obliged to comply.

Promotional Content:

For bulk message (Ads and promotions, anything non-transactional) sender ID 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 content is allowed only between 8am & 10pm Saudi Arabia time (GMT +03:00).

Transactional Content:

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.



No Adult content is allowed.


No political content is allowed.


No religious content is allowed.


Unicode is fully supported, other than the '£' (pound sign) which is not accepted.

Concatenated messages:

Concatenated messages are not supported.

Other features/restrictions of note:

Delivery Receipts:
Handset delivery receipts are not supported.
