NHN Cloud bulk SMS setup for Ultra SMS

Steps

1. In the NHN Cloud console open Notification, then SMS.
2. Copy the App Key and Secret Key.
3. Use a calling number registered on the service as the send number.
4. In Ultra SMS open the Gateways tab, click Add gateway, choose NHN Cloud SMS, and paste both keys and enter the send number.
5. Send a test message to your own phone before you start a campaign.

Good to know

• Bodies use EUC-KR, and a standard SMS is 90 bytes. Text outside Korean and Latin characters may not send.
• There is no read-only account check for this gateway, so Test credentials cannot verify the login. Send a test SMS to your own number instead.

Before you send through NHN Cloud SMS

NHN Cloud SMS 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.
