IM2SMS

IM2SMS is a phone & sms application developed by Goldmaster, packaged as a single Android APK of version 1.6 weighing in at 15.95 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
2. File size is a light 15.95 MB, so it installs quickly even on modest connections.
3. This build is signed by "Goldmaster" — always verify the developer name matches what's listed on the app's official store page before installing an update.
4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

A simple app to import IM chat histories into Android’s SMS storage.

Planned Support:

Facebook Messenger: Support for importing from a Facebook data takeout is planned.

Telegram: Future support is planned.

Signal: Future support is planned via backup files or secure backups.

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?
There is basic support for importing group chats, however, there are significant limitations due to how Android and apps like Google Messages handle the legacy SMS/MMS storage. At present, there is no way for third-party apps to programmatically set a group chat name in the system's SMS database that Google Messages will recognise, so the chat name will typically appear as a list of participant numbers. Additionally, a "Mass Text" warning may show if Google Messages cannot verify that all participants are using modern RCS (Rich Communication Services). To fully continue a group chat as a single thread, all members must be using RCS. Once everyone is on RCS, the group chat should automatically "upgrade" and function as a normal group thread.

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.

Is IM2SMS free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does IM2SMS require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is IM2SMS safe to install?
We link to the exact APK published by Goldmaster. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update IM2SMS?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.

1. Tap the Download APK button above and save the file to your device.
