Malaysia: SMS Features and Restrictions

Malaysia is a major SMS market which is continuing to grow in size. Along with this growth however, many problems are arising. Carriers in Malaysia are implementing more and more spam filters to prevent A2P traffic reaching their network via international SS7 routes.

Spam filters can sometimes return in fake delivery receipts and don’t discriminate between spam and legitimate traffic. Therefore, you may think the route is working fine when it is not, in reality a large amount of messages on low cost signalling routes are being blocked. Nexmo is pleased to announce that we are now using a direct connection to all networks in Malaysia.

This will improve the “real” delivery ratio and allow sensitive applications such as financial alerts and password delivery to reach the phone. It is a high-quality, stable route which in combination with our adaptive routing will help to guarantee message delivery in Malaysia.


Sender ID:

Sender IDs are all overwritten with a random Shortcode or occasionally a Malaysian number. 


Please be informed that Operators in Malaysia has tightened the rules and penalties whereby all traffic must include company name/brand/identity in the SMS content, else penalty might be imposed by the operator. These messages are to be used for A2P purposes only (OTP, transactional and marketing). 

Adult content:

Adult content is not allowed.

Political content:

Political content is not allowed.

Religious content:

Gambling content:

Content modifications:

Please note that "RM 0.00 " (with a space after the last 0) may be added to message bodies. This is done to inform end users that they were not charged to receive this message. If you have not added this to your message body, the operator will automatically add it and may compromise the maximum length of your SMS.

There are no other additional content restrictions beyond those in our Acceptable Use Policy

Concatenated messages:
