Fast2SMS bulk SMS setup for Ultra SMS
A popular Indian bulk SMS service with a DLT route and a simple API key.
What Ultra SMS asks for
| API authorization key | Fast2SMS dashboard, Dev API. |
|---|---|
| Route | DLT (your own sender ID + template), or Quick SMS (no DLT, random sender, costs more). |
| Sender ID and DLT Entity (PE) ID | Your approved DLT header and Entity ID, added in Fast2SMS's DLT Manager. |
| DLT template ID | The template ID shown in DLT Manager: per campaign, or as the gateway's Default template ID. |
Steps
- Create a Fast2SMS account and recharge your wallet.
- Open DLT Manager and add your Entity ID, sender ID and approved templates.
- Copy the API authorization key from Dev API.
- In Ultra SMS add a gateway, choose Fast2SMS, paste the key, choose the DLT route, and enter the sender ID and Entity ID.
- Send a test message with an approved template.
Good to know
- 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.
- Use the DLT route for business SMS. The Quick SMS route costs more, sends from a random number and is not meant for bulk sending.
- Fast2SMS sends to Indian (+91) numbers only.
Before you send through Fast2SMS
Sending to Indian numbers needs DLT registration whichever gateway you use: your entity, approved sender IDs and approved templates, added to Ultra SMS so each message carries them. Fast2SMS charges per message segment at its own rates, so check the segment counter and the cost estimate before you start. 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.
