Rules & regulations
What local regulators expect before you send, as the destination's own policy record states it.
This country has mandatory registration, and senders can be used only by clients who registered the sender and provided all documentation for approval. We can not register the sender ID on behalf of the client. Client has to register directly on the SSIR portal by following the steps on this page: https://sgnic.sg/faq/sms-sender-id-registry Once the registration is completed, and SSIR letter of confirmation has been sent to the Client. Client has to submit a letter and ACRA document for internal sender approval. Unregistered sender ID can be approved from our side and if client accepts manipulation of the sender ID to generic sender Likely-SCAM.
What this market refuses
Unsolicited SMS from unknown sources related to loans, financial assistance, adult content, or online gambling/betting are considered spam and are not allowed. Any message that arrives to the user who did not request the message can be reported to the Regulatory, and in this case, the Local Police is involved.
One API
How sending works
You send to every destination through the same endpoint and the same keys. Bird picks a compliant route for the country, applies opt-out handling on every message, and reports delivery from carrier receipts. The country-specific part is which sender you register. The API call does not change.
