Nulled Zender - Messaging Platform for SMS, WhatsApp & use Android Devices as SMS Gateways (SaaS) V3.9.7

What's New?​

You can now send SMS without setting the app as the default SMS app, just like in the legacy version.

However, receiving SMS still requires the app to be set as default. You can easily set it by tapping the new option in the top-right menu of the app bar.

To remove Zender Gateway as the default app:

Just open your device’s built-in SMS app and set it back as default. After that, open the Zender Gateway app again and it will request the standard SMS permissions.
