# How to send 1000 SMS at once?

To send 1000 SMS at once, upload a contact list (via CSV/Excel file or a saved group) to a bulk SMS platform, select a DLT-approved message template and sender ID, then trigger the send using either the platform's Quick Send / Group Send tool or the SMS API for automated delivery.

Step-by-step:

1. Ensure your sender ID and message template are [DLT](https://www.smsgatewaycenter.com/dlt-sms/)-registered (mandatory for Indian telecom compliance).
2. Import your 1000 recipient numbers using file upload or an existing contact group.
3. Select the message type — Transactional, Promotional, or OTP — based on use case.
4. Choose Quick Send for a one-time blast or the API/SMPP route for recurring or app-triggered sends.
5. Review the delivery report to confirm status across all 1000 recipients.

Platforms like **SMSGatewayCenter** support all of the above through the dashboard's [File Upload](https://www.smsgatewaycenter.com/blog/kb/how-to-send-sms-using-file-upload-method-mobile-only/) and [Group Send](https://www.smsgatewaycenter.com/blog/kb/how-to-send-sms-using-group-send-method/) methods, or programmatically via API for higher volumes.
