Keep SIM Alive sends an SMS on the schedule you define so your prepaid, roaming, or backup SIM card is never deactivated for inactivity.
How it works
For each SIM on the device you set a recipient, a message, and a schedule for when the message goes out. Each keep-alive is a regular SMS: your carrier may charge for it as per your plan.
Features
Privacy
The app has no internet permission and makes no network calls: keep-alive messages are sent directly over the cellular network and all data stays on your device. No advertising, no tracking, no analytics.

Permissions
- Send SMS — the keep-alive message itself
- Read phone state — to properly link the schedule to a certain SIM card
- Show notifications — recommended for sticky notification
- Boot completed — to re-arm the schedule after a reboot
- Ignore battery optimizations — optional but recommended, for reliable wake-ups
- Schedule exact alarms (Android 12+) — optional and experimental, for wake-ups despite aggressive battery optimizations; recommended on devices known to kill background apps. On Android 12-14 you grant it via a separate Alarms & reminders toggle, and on Android 15+ the battery exemption above grants it automatically
