Been facing this issue and we need to implement a two way scenario for higher and lower android sdks to solve this in the long run

 // For newer SDKs, use SubscriptionManager, for older, use TelephonyManager directly
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
        // Use SubscriptionManager APIs for newer versions
    } else {
        // Use TelephonyManager.getSimSerialNumber(), etc. for older versions
    }

    return simCardNumbers;
}
