Compliance considerations	Per local regulations, only Person-to-Person (P2P) messages may be sent via Malaysian domestic long codes. If you can guarantee that you only send legitimate P2P messages, please reach out to Twilio Customer Services to ensure the proper domestic long code connectivity is enabled on your account. For Application-to-Person (A2P) messages, you can use any international long codes. For all messages submitted to Malaysia, you must include your brand name to avoid blocking and filtering by mobile operators. Brand names in message content allow mobile operators to identify which organizations are sending messages to their subscribers. The Sender ID of A2P messages to Malaysia is overwritten with a Shortcode Sender ID. Sending political, religious, and gambling-related content is strictly prohibited. Malaysian mobile operators require the content header `RM 0.00` is added to every message sent to Malaysia. This header tells the receiving subscriber that they were not charged for receiving the SMS message. Sending your messages without this header will result in the content being truncated or the message failing entirely. Concatenated messages are supported by all mobile operators except Digi Malaysia which delivers them as multiple separate messages. Twilio strongly encourages customers to review proposed use cases with qualified legal counsel to make sure that they comply with all applicable laws. The following are some general best practices: Get opt-in consent from each end-user before sending any communication to them, particularly for marketing or other non-essential communications. Only communicate during an end-user’s daytime hours unless it is urgent. SMS campaigns should support HELP/STOP messages, and similar messages, in the end-user’s local language. Do not contact end-users on do-not-call or do-not-disturb registries.
