Jnto Gateway

JNTO is the powerful SMS Gateway app that transforms your Android phone into a remote SMS and MMS sending device, controlled through a secure web dashboard. Send, receive, and manage messages from any browser - while your phone does the actual carrier work in the background.
Whether you're running bulk SMS campaigns, automating customer outreach, or building a custom messaging workflow, JNTO connects your phone and dashboard seamlessly with real-time, two-way sync.

How JNTO Works

JNTO becomes your phone's default SMS app, taking full control of sending and receiving SMS and MMS messages. Link your phone to your backend account by simply scanning a QR code. From that moment on, every text you send or receive is mirrored instantly to your web dashboard - and every message triggered from the dashboard is sent through your phone's SIM via Android's native messaging system.
