SIM Manager – SIM Scheduler

alceit

À propos de l'application

Separate work and personal numbers, switch SIMs automatically when you travel between time zones, or get a loud lockscreen wake-up before an important plan triggers.

🔹 Key Features

▸ Smart SIM Scheduling
Create plans with date, time, and repeat (one-time, daily, weekly with weekday selection, monthly). Plans survive reboots, time-zone changes and missed executions.

▸ Physical SIM & eSIM Support
Manage physical SIM slots and currently-active eSIM profiles in one dashboard with carrier names, slot status and one-tap actions.

▸ Alarm Mode (new in v1.2)
Per-plan choice between Notification, Alarm (full-screen lockscreen wake-up + ring), or both. You decide how loud each plan is.

▸ Timezone Pinning (new in v1.2)
Bind a plan to a specific IANA timezone (e.g. Europe/Berlin). The plan fires at local time of that zone, regardless of where your phone currently is. DST-safe.

▸ Plan Names (new in v1.2)
Give each automation a meaningful title — "Work profile", "Vacation USA", "Weekend travel". Or leave it blank: a smart default takes over.

▸ Live SIM Status
Dashboard reflects the real slot and carrier state. Toggle a SIM in Android Settings — the app updates within ~1 second, no restart.

▸ Execution Log
Every plan run is recorded with timestamp, result, and error message. Full transparency about what happened when.

▸ Backup & Restore
Export plans and profiles as JSON. Versioned schema (v1, v2, v3) — old backups read forward without data loss.

▸ Atlas UI
Dark-only design system with Syne, Fraunces and Space Mono via Google Fonts. Twelve composables, ten redesigned screens.

🔹 How automatic SIM switching works

▸ eSIM profiles
Switched automatically via the standard Android EuiccManager API on every supported Android version, provided the device is eSIM-capable.

▸ Physical SIM, rooted device, Android 13 / 14
Switched automatically via shell command.

▸ Physical SIM, rooted device, Android 15 / 16
The app tries a multi-method cascade and verifies each step against the live subscription state. Best-effort: for the majority of mainstream devices the cascade succeeds; for exotic ROMs, future Android versions whose internals shift, or device-specific modem restrictions it may not.

▸ Physical SIM, non-rooted device — or rooted but cascade can't reach the modem
At the scheduled time you receive a notification or alarm-style reminder with a one-tap deep-link to the system SIM manager. The actual switch happens with two taps. The app never silently misses a plan: if the automatic path fails, the fallback notification always triggers.

Automatic fallback to notification when an automatic switch is impossible: if every cascade strategy fails on a rooted device, the App writes a failure entry to its execution log and shows the same notification + tap-to-settings deep-link as in non-rooted mode.

What the App does not promise: a guaranteed automatic switch on every combination of Android version, manufacturer, and ROM. Switching depends on the device's modem and operating system honoring the standard Android subscription-toggle APIs. The Provider has no influence over manufacturer-specific modem implementations or future changes to Android. The notification fallback ensures the App stays useful even when the automatic path is blocked at the device level.

Nouveautés

• 14 app languages — follows your system language, switchable in Settings.
• Android 16 ready (targetSdk 36), edge-to-edge on every screen.
• Fixed: a missed alarm could re-trigger on every app start and could not be dismissed. "Dismiss" now resolves the cycle for good.
• More reliable audible alarm after a reboot.
• Many smaller display fixes found while translating.
