Amazon SNS bulk SMS setup for Ultra SMS

Steps

1. Create an IAM user for Ultra SMS with only the permission to publish SMS, and create an access key for it.
2. New AWS accounts start in the SMS sandbox: you can only text verified numbers. Request production access in the SNS console.
3. AWS also sets a low monthly SMS spending limit on new accounts. Ask AWS Support to raise it, or sending stops when the limit is reached.
4. Set the default message type to Transactional or Promotional to match what you send.
5. In Ultra SMS add a gateway, choose Amazon SNS, paste the keys and pick the region.
6. Send a test message to your own phone.

Good to know

• Sending to US numbers from an ordinary 10-digit number needs A2P 10DLC registration (a brand and a campaign) in the gateway's console first; toll-free numbers need toll-free verification. Unregistered US traffic is blocked or filtered by the carriers.
• Sending to Indian numbers needs DLT registration: your Entity ID, an approved sender ID (header) and the Template ID of an approved content template. Ultra SMS has fields for all three. See the India DLT chapter of the manual.

Before you send through Amazon SNS

Amazon SNS charges per message segment at its own rates, which depend on the destination country. Check that your sender is allowed in each country you text. Business traffic to the USA normally needs A2P 10DLC registration or a verified toll-free number, and India needs DLT registration. Use Test credentials first, then send one real test to your own phone.

Dashboards change their menus from time to time; if a label differs, look for the API keys or developer section. Stuck? See the Ultra SMS troubleshooting table, the Ultra SMS user guide, or contact us.
