Sim Ejection Analysis

​

Getting SIM Ejection Data

Each SIM ejection event contains the following properties:

• state: The state of the SIM card, which can be one of the following:
  • LOADED: The SIM card is loaded and ready to use.
  • READY: The SIM card is in a ready state.
  • ABSENT: The SIM card has been removed.
  • CARD_IO_ERROR: There was an error reading the SIM card.
• transactionTime: The timestamp when the state was recorded.

​

1. Set SIM status change listener

You can fetch a list of SIM ejection events that occurred on the user’s device by directly querying the OTPless SDK. This method is ideal for reviewing historical and latest data.

​

Usage Example:

// Instantiate `OtplessSimUtils`
const otplessSimUtils = OtplessSimUtils.getInstance();

otplessSimUtils.setupSimStatusChangeListener(handleSimStatusChange);

const handleSimStatusChange = (simEntries: any[]) => {
    console.log('Received SIM status changes:', simEntries);
};

​

2. Clear SIM status change listener

To clear the listener when it is no longer needed, call:

otplessSimUtils.detachSimEjectionListener();

​

3. Query historical SIM ejection entries

To fetch past sim ejection entries, use the following code:

try {
    const entries = await otplessSimUtils.getEjectedSimsEntries();
    console.log("Ejected SIM Entries:", entries);
} catch (error) {
    let errorStr = "Error fetching ejected SIM entries: " + error;
    console.log(errorStr)
}
