# What is a BulkSMS gateway?

A [bulk SMS gateway](https://www.smsgatewaycenter.com/sms-gateway/) is a platform or API that lets businesses send large volumes of SMS messages to multiple recipients simultaneously, instead of sending texts one at a time from a phone. It connects a business's website, CRM, or application directly to mobile network operators, converting messages sent through software into standard SMS delivered to any mobile number.

In India, a compliant bulk SMS gateway also handles [DLT](https://www.smsgatewaycenter.com/dlt-sms/) (Distributed Ledger Technology) registration requirements - validating sender IDs and message templates against TRAI regulations before delivery, so businesses don't get messages blocked for non-compliance.

SMSGatewayCenter's bulk SMS gateway supports file upload, group sends, and API/[SMPP](https://www.smsgatewaycenter.com/smppConnectivity/) integration, with built-in DLT compliance checks for the Indian market.
