Zender - Ultimate Messaging Platform for SMS, WhatsApp & use Android Devices as SMS Gateways (SaaS) v3.9.8

What’s New in v3.9.8​

New Android App

We are excited to announce the newly re-engineered Zender Gateway App. This version has been completely rewritten to ensure stable and consistent performance across all Android versions. After several days of extensive testing, we are confident that this is the most reliable and refined gateway app since Zender’s first release. Now, it's not required to make the app default sms app just to receive messages.

The new app now includes localization support, with initial languages available in English, Japanese, Arabic, and Chinese. Additional languages will be introduced in upcoming updates. The old android app in user devices must be uninstalled so the new apk can be installed.

New WhatsApp Server

The WhatsApp server has been rebuilt from the ground up using a native language, offering significantly improved stability and memory efficiency compared to the previous binary implementation.

Please note that reconnecting all WhatsApp accounts is required to use this new version, as the old server is no longer compatible and must be fully replaced. Installation and setup procedures remain the same as before.
