Sending SMS to landline numbers	You cannot send SMS to a landline destination number: the Twilio REST API will throw a 400 response with error code 21614, the message will not appear in the logs, and the account will not be charged.
Compliance considerations	Per local regulations, only person-to-person (P2P) messages may be sent via Malaysian long numbers. Please use other global SMS-capable numbers such as US and Canadian numbers to send application-to-person (A2P) messages. For all messages submitted to Malaysia, it is required to include the brand name to avoid blocking and filtering by mobile operators. The brand name in the content would allow mobile operators to identify which brands are sending messages to their subscribers. Note that the Sender ID of Application-To-Person 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 ' to be added in 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 would result in the content being truncated or the message failing entirely. Concatenated message is supported by all mobile operators except Digi Malaysia where it is delivered 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.
