Tencent Cloud bulk SMS setup for Ultra SMS

Steps

1. In the Tencent Cloud SMS console add an application to get the SmsSdkAppId.
2. Get a template approved under Global SMS. It must have exactly one variable, {1}.
3. Create an API key in the Tencent Cloud account (SecretId and SecretKey).
4. In Ultra SMS open the Gateways tab, click Add gateway, choose Tencent Cloud SMS (template only), and enter these values and pick the region.
5. Send a test message to your own phone before you start a campaign.

Good to know

• Ultra SMS puts your whole message into the template's single {1} variable, and non-enterprise variables are limited to 12 characters.
• 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.
• This gateway has no delivery look-up in Ultra SMS, so its messages show as Sent, not Delivered. Check the gateway's own dashboard or reports for final delivery.

Before you send through Tencent Cloud SMS

Tencent 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.
