Malaysia SMS Features and Restrictions


Malaysia is a major SMS market that 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 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 signaling routes are being blocked.

Vonage uses a direct connection to all networks in Malaysia. This improves the real delivery ratio and allows 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 to a random short code or occasionally an international long number.


Operators in Malaysia have tightened the rules and penalties whereby all traffic must include brand, company name, or identity in the message bodies, or else penalties might be imposed by the operators on top of the standard SMS charges. These messages are to be used for A2P purposes only (OTP, transactional, and marketing).

There is a split of international and domestic traffic based on what brand, company name, or identity you are going to include in your messages and we are able to provide better price for traffic that can be categorized as domestic. Contact your account manager for more details.

Prohibited Content

Adult, political, gambling, racial, and religious content are not allowed.

Content Modifications

"RM0.00 ," "RM0.0 ," or "RM0 " (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 these messages. If you have not added this to your message body, the operator will automatically add it and this may compromise the maximum length of your SMS.

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


Unicode is supported.


Binary is supported.

Concatenated Messages

Concatenated messages are supported to all networks except DiGi (502 16).

Other Features or Restrictions

Delivery Receipts

Delivery receipts are network receipts and therefore should not be taken as an accurate measure of delivery.
