FAQ

Will an iOS version be available?

No. Due to technical limitations, iOS does not allow third-party apps to write to the SMS database.

Why export to SMS?

SMS is a universal, device-native format. By converting chat histories to SMS, you get a durable, open-standard backup that isn't locked into a single proprietary app.

Why the name?

The name stands for Instant Messenger to SMS. It reflects the app’s broad support for multiple IM platforms beyond just WhatsApp.

Can group chats be imported?

Currently only previewing group chats is possible. Future support for RCS may allow importing into phone storage.

Can I use IM2SMS to back up my existing SMS messages?

No. The core purpose of IM2SMS is to import Instant Messenger chat histories into the phone's SMS storage. Creating backups of existing SMS messages is already well-supported by other dedicated apps.

Why does the app have to be set as the default SMS app?

Android only allows the current default SMS app to write to the system's message database. To import chats, IM2SMS must temporarily become the default app. After the import process completes, opening the preferred messaging app provides a prompt to restore it as the default.
