SimManager – Intelligent SIM Management for Android

§ 01 · Features

Eleven features. One SIM control.

From alarm-style reminders to live carrier status — SimManager v1.2 covers every realistic SIM-switching scenario without leaving your device.

FR-01

Schedule-based SIM control

Plans with date, time, and recurrence (one-time, daily, weekly, monthly). SIMs flip automatically at the right moment.

FR-02

eSIM automation

Switch eSIM profiles via Android EuiccManager. No manual taps — perfect for travelers juggling multiple data plans.

FR-09

Alarm mode

New in v1.2: choose Notification, Alarm (full-screen lockscreen wake-up + ring), or both. Per plan, you decide how loud.

FR-10

Timezone pinning

Bind a plan to an IANA zone (e.g. Europe/Berlin). DST-safe via java.time. Plans don't drift when you travel.

FR-12

Plan names

"Work profile", "Vacation USA", "Weekend travel" — give each automation a meaningful title. Or leave blank: a smart default takes over.

FR-15

Live SIM status

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

FR-03

Advanced mode (Root)

On rooted devices the app flips physical SIM slots automatically. Magisk, SuperSU, KernelSU supported. Confirmed on Android 13 / 14; best-effort on 15+ — if the modem rejects every method, you get an honest failure notification with one-tap deep-link to the SIM manager. Never a silent miss.

FR-04

Carrier-aware reminders

No root, or root automation didn't reach your modem? At trigger time you get a notification reading "Vodafone · Slot 1" with a one-tap link to the SIM manager.

FR-05

Execution log

Every run is recorded — timestamp, result, error message. Full transparency about what happened when.

FR-06

Backup & restore

Export plans + profiles as JSON. Versioned schema (v1, v2, v3) — old backups read forward without data loss.

NFR-01

Offline & private

Zero cloud. Zero analytics. Zero ads. Android Keystore for sensitive data. GDPR-compliant by architecture.

NFR-08

Atlas UI

Dark-only design system, Syne + Fraunces + Space Mono via Google Fonts, twelve composables, ten redesigned screens.

2. Data We Collect

SimManager collects and stores the following data only on your device:

SIM plans and profiles: Names, schedules, and SIM slot assignments you configure.
Execution logs: Timestamps and outcomes of plan executions.
Root manager detection: The app may query whether Magisk, SuperSU, or KernelSU are installed. This information is not stored or transmitted.

We do not collect account data, crash reports, or any personally identifiable information beyond what you enter locally (e.g. plan names).

3. How We Use Your Data

All data is used solely to provide app functionality:

SIM plans and profiles are used to perform scheduled SIM switching.
Execution logs are shown to you in the app's log screen.
Root status is used to offer root-based SIM control when available.

No data is sent to our or any third-party servers.

4. Data Sharing

We do not share your data with any third parties. All data remains on your device.

5. Root Access Explanation

If you use root-based SIM control, the app may use elevated privileges to switch the active SIM. Root access is used only for this purpose. We do not store, log, or transmit any root-related data. The app uses the Android package visibility API (<queries>) to detect which root manager is installed locally; this check is performed locally and no result is sent elsewhere.

6. Data Retention

Data is retained as long as the app is installed and you do not clear app data. If you uninstall the app or clear its data, all stored plans, logs, and settings are removed from the device.

Terms of Service

Last updated: April 2026 · SimManager for Android

1. Scope and Provider

These Terms of Service govern the use of the SimManager mobile application ("App"), provided by ALCEIT – Ali Celebi, Waldenbucher Str. 23, 71032 Böblingen, Germany ("Provider"). By downloading, installing or using the App you accept these Terms. If you do not agree, please do not install or use the App.

2. License

The Provider grants you a non-exclusive, non-transferable, revocable right to install and use the App on your compatible Android devices for private or internal business use. All intellectual property rights in the App remain with the Provider.

3. Purchase via Google Play

The App is distributed exclusively through the Google Play Store as a one-time purchase of €1.99. Billing, payment processing and refund handling are performed by Google under Google's own terms and refund policy. The Provider has no influence over these processes.

4. Permitted Use

The App may only be used for its intended purpose: scheduling and controlling SIM profiles (eSIM and physical SIM) on compatible Android devices. You are responsible for ensuring that such use is permitted under your mobile carrier contracts and applicable law in your jurisdiction.

5. Prohibited Use

The following is expressly prohibited:

Reverse engineering, decompiling or disassembling the App, except to the extent permitted by mandatory law.
Redistributing, selling, renting or sublicensing the App to third parties.
Using the App for unlawful purposes or to circumvent security measures of your device or mobile carrier.
Bypassing the license check or the purchase process.

6. Root Features (Advanced Mode)

The so-called "Advanced Mode" uses root privileges on suitably prepared devices. Rooting a device can void the manufacturer's warranty and may increase security risks. Use of root features is entirely at your own risk. The Provider is not liable for damages arising from rooting itself or from actions performed with elevated privileges.

7. SIM-Switching Functionality and Realistic Expectations

What the App will do:

eSIM profiles: switched automatically via the standard Android EuiccManager API on every supported Android version, provided the device is eSIM-capable.
Physical SIM slots, rooted device, Android 13 / 14: switched automatically via shell command. Confirmed on common manufacturers (Pixel, Samsung, Xiaomi, OnePlus).
Physical SIM slots, rooted device, Android 15 and above: the App attempts a multi-strategy cascade (legacy shell command, reflective binder discovery, transaction-code sweep). Each step is verified 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 slots, non-rooted device: at the scheduled time you receive a notification or alarm-style reminder containing a one-tap deep-link to the system SIM manager. The actual switch happens with two taps.

Automatic fallback when an automatic switch is impossible: if every cascade strategy fails on a rooted device, the App writes an honest failure entry to its execution log and shows the same notification + tap-to-settings deep-link as in non-rooted mode. The user is never left in the dark and never sees a silent miss.

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.

8. Updates and Availability

The Provider strives to keep the App up to date and to release regular updates. There is no entitlement to specific features, compatibility with future Android versions, or uninterrupted availability. Updates may be required for the App to continue functioning correctly.

9. Warranty

The App is provided "as is". Statutory warranty rights for consumers remain unaffected. Beyond the legally required provisions no guarantee is given for specific features, fitness for a particular purpose, or freedom from defects. In particular, no warranty is given that the automatic SIM-toggle path will succeed on every combination of Android version, device manufacturer or modem firmware; the notification fallback described in section 7 remains available regardless.

10. Liability

The Provider is liable without limitation for intent and gross negligence as well as for injury to life, body or health. For slight negligence the Provider is only liable for the breach of material contractual obligations (cardinal obligations) and limited to foreseeable damages typical for this type of contract. Any further liability is excluded. In particular, the Provider is not liable for connection losses during SIM switching, missed automatic switches due to device or carrier restrictions, data loss, lost profits or indirect damages.

11. Third-Party Services

The App uses functionality provided by Google (Google Play Store, EuiccManager API) and Android system components. The terms of the respective providers apply to those services.

12. Termination

You may end your use of the App at any time by uninstalling it. The Provider may revoke the license in the event of serious breaches of these Terms.

13. Changes to the Terms

The Provider may amend these Terms in case of material changes. The current version is always available at https://alceitlabs.com/awesome-simmanager.html.

14. Applicable Law & Jurisdiction

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer protection provisions of the country in which the user has their habitual residence remain unaffected. For merchants the place of jurisdiction, to the extent legally permissible, is Böblingen, Germany.
