// you may ignore TelephonyManager if you don't want to get the IMEI
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

SubscriptionManager subscriptionManager = SubscriptionManager.from(getApplicationContext());
List<SubscriptionInfo> subsList = subscriptionManager.getActiveSubscriptionInfoList();

for (SubscriptionInfo subscriptionInfo : subsList ) {
    // get IMEI
    int simSlotIndex = subscriptionInfo.getSimSlotIndex();
    String imei = telephonyManager.getImei(simSlotIndex);

    // get serial number
    String serialNumber = subscriptionInfo.getIccId();

    // get line number
    String lineNumber = subscriptionInfo.getNumber();
}
