I'm setting up an SNS (Simple Notification Service) system and ran into an issue when trying to add a phone number for SMS notifications. I received an error saying, 'An error occurred while attempting to add a phone number to the SMS sandbox. The phone number was not added. Error code: UserError - Error message: No origination entities available to send.' I realized this is because I need to register an origination number in AWS, but the verification process could take up to two weeks. Is there a way to register a phone number quickly for sending texts, especially since this is just for a sandbox environment?

Sending SMS through AWS can be a bit tricky because they implement strict measures to prevent spam and comply with telecom laws. In a sandbox environment, you can send messages to verified numbers without issues, so don't worry too much about the sender number just for testing purposes. Just ensure you're adding the numbers you need to the sandbox.
How do I go about doing that? Any guides you recommend?
