SIM Flip: One-Tap Switch

Switching your data SIM takes too many taps.

Settings → Network → SIM cards → pick the other SIM. Every single time.
If you carry two SIMs — a local one abroad and your home number, or one for work
and one for personal — you do that dance several times a day.

SIM Flip turns it into one tap.

■ How it works

Android does not let any app change the data SIM directly. There is no public API
for it, and this app does not pretend otherwise.

Instead, you teach it once:

1. Tap "Start recording"
2. Switch your SIM by hand, the way you always do
3. Tap "Stop recording" and save the steps as SIM 1 or SIM 2

From then on, one tap replays exactly those steps for you. The app opens Settings,
taps the same buttons in the same order, and gets out of the way.

Because it replays YOUR steps on YOUR phone, it works across manufacturers —
Samsung, Xiaomi, OPPO, Pixel and others — even though every Settings screen is
laid out differently.

■ Features

・One-tap switching from the app
・Home screen widget — switch without even opening the app
・App-linked switching — open a chosen app and the SIM switches automatically
(for example: open your work chat app, and the work SIM takes over)
・Optional extra steps — record a few taps to run inside that app after the switch
・Three playback speeds
・Everything is stored on your device only

■ About the Accessibility Service

This app uses Android's Accessibility Service to replay your recorded taps.
That is the only way an app can operate the Settings screen on your behalf.

・It reads on-screen button labels and positions, to replay your steps correctly
・It detects which app is in the foreground, for app-linked switching
・All of this is processed on your device. Nothing is sent anywhere, shared with
anyone, or collected — and it is never used for advertising or analytics
・You can turn the service off at any time from your device's Settings

■ Good to know

・Requires a dual-SIM phone (or one physical SIM plus an eSIM)
・Battery optimization can stop the service on some phones. The app shows you how
to prevent that
・This app is free and supported by ads
