An SMS gateway connects your software to mobile networks so you can send SMS at scale. SMS marketing software sits on top of it, giving your team a panel for contacts, campaigns and reports. This guide helps you choose both.
Best SMS gateway provider: 7 checks
- Direct operator routes. In India, links to Jio, Airtel, Vi and BSNL. Read about our SMS gateway.

- HTTP API and SMPP. See the SMS API and SMPP.
- Delivery reports per message, by API and in the panel.
- DLT support for headers and templates in India.
