I hit this error and noticed in the Azure portal that my toll-free number had a "Submit verification" link on the SMS column under Phone numbers. Seems there's a whole verification process and it can take up to 5 weeks to approve. I am trying to send SMS notifications from health checks for a single application, not do a commercial SMS campaign, so I am looking into pricing for third party SMS APIs.

From https://learn.microsoft.com/en-us/azure/communication-services/concepts/sms/sms-faq#toll-free-verification: Effective January 31, 2024, the industry’s toll-free aggregator is mandating toll-free verification and will only allow verified numbers to send SMS messages.

Typically, the 202 returned by the service, indicate that your message has been queued to be sent and not delivered. Please review/follow this guide to subscribe to delivery report events and troubleshoot. Once the events are configured, inspect the "deliveryStatus" field of your delivery report to verify delivery success/failure.

Also, please review the limits in sending messages/ref SMS FAQ doc.
