在我的应用程序中，我使用 . 检查 Sim 是否存在simState == TelephonyManager.SIM_STATE_ABSENT。如果 Sim 存在，我将收集所有 Sim 信息，例如 Sim 运营商名称、Sim 国家/地区等。如果我关闭 WiFi，即使它存在，我也会得到 Sim 缺席，并且我没有得到任何 Sim 详细信息。（电话管理员无法访问 sim当 wifi 未连接时。）

  1. WiFi关闭时，还有其他方法可以获取SIM卡信息吗？
TelephonyManager telephonyManager =
  ((TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE));
int simState = telephonyManager.getSimState();
if (simState == TelephonyManager.SIM_STATE_ABSENT){
        Log.d("hello", "network disconnected"); 
        operatorParam.add("Not found");
        operatorParam.add("Not found");
        operatorParam.add("Not found");
        operatorParam.add("Not found");
        operatorParam.add("Not found");
        operatorParam.add("Not found");

    } else {

        Log.d("hello", "network connected");
        if (telephonyManager.getNetworkOperatorName() != null) {
            operatorParam.add(telephonyManager.getNetworkOperatorName());
            Log.d("operator", "getoperator name not null: "
                    + telephonyManager.getNetworkOperatorName());

        } else {
            operatorParam.add("Not found");
        }

        if (telephonyManager.getSimOperatorName() != null) {
            operatorParam.add(telephonyManager.getSimOperatorName());
        } else {
            operatorParam.add("Not found");
        }

        if (telephonyManager.getSimOperator() != null) {
            operatorParam.add(telephonyManager.getSimOperator());
        } else {
            operatorParam.add("Not found");
        }

        if (telephonyManager.getSimSerialNumber() != null) {
            operatorParam.add(telephonyManager.getSimSerialNumber());
        } else {
            operatorParam.add("Not found");
        }

        if (telephonyManager.getSimCountryIso() != null) {
            operatorParam.add(telephonyManager.getSimCountryIso());
        } else {
            operatorParam.add("Not found");
        }

        if (telephonyManager.getSubscriberId() != null) {
            operatorParam.add(telephonyManager.getSubscriberId());
        } else {
            operatorParam.add("Not found");
        }


       }

提前致谢。
