Twilio concatenated message support Concatenation refers to the capability of splitting a message that is too long to be sent in one SMS into smaller pieces and then joining the pieces at the receiving end so that the receiver sees the message as one.	Yes* For certain sender ID types this may not be supported. Where messages are split and rejoined may vary based on character encoding.

Compliance considerations Twilio strongly encourages customers to review proposed use cases with qualified legal counsel to make sure that they comply with all applicable laws. This table lists some general best practices.	Sender ID Compliance Sender ID Registration is required in Qatar. Unregistered Sender IDs will be overwritten with a generic Alphanumeric Sender ID outside of the Twilio platform and delivery will be attempted on a best-effort basis only. The enforcement of complete blocking of unregistered Sender IDs in Qatar is on August 11, 2025. Twilio highly recommends sending from a registered Alphanumeric Sender ID to avoid having your messages blocked. Content Compliance Requirements for SMS Delivery to Qatar Adult, political, governmental, and religious content is prohibited. Messages containing such content will be filtered out and accounts deny-listed. Additional Phone Numbers and Sender ID Guidelines 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.

Use case restrictions	Adult, political, governmental, and religious content is prohibited. Messages containing such content will be filtered out and accounts deny-listed.	Sender ID Registration is required in Qatar. Sending messages via an Alphanumeric Sender ID which is not registered will result in best effort based delivery.
Best practices	Local network operators tend to deactivate Sender IDs which were registered in the past but are not used for a considerable period of time. We suggest our clients making sure that they keep sending traffic periodically to the specific destination once they register their Alpha Sender IDs. If the Sender ID is deactivated due to inactivity then the customer needs to re-initiate the registration procedure.	Twilio suggests using a pre-registered Alphanumeric Sender ID in Qatar.
