副 SIM 卡的 MNC 和 MCC

Question

我知道使用 TelephonyManager 我们可以获得网络提供商的 MNC 和 MCC，

TelephonyManager tel = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String networkOperator = tel.getNetworkOperator();

if (networkOperator != null) {
    int mcc = Integer.parseInt(networkOperator.substring(0, 3));
    int mnc = Integer.parseInt(networkOperator.substring(3));
}

但我只能获取主 sim 的 MNC 和 MCC 数据。我想知道有没有办法在 android.

中获取设备的辅助 sim 卡的 mnc、mcc、lac 和 cellid

Answer 1

在API22之前，很难达到你想要的。

我相信在 API 22 之前，Android 最初不支持双卡双待。因此，每个移动供应商都应该有自己的实现。也许，您应该获取他们的 APIs/SDKs 并将它们包含到您的项目中。只有这样，您才能访问他们的 APIs.

从 API22 开始，我认为您可以使用 SubscriptionManager

    int mccSlot1 = -1;
    int mccSlot2 = -1;
    int mncSlot1 = -1;
    int mncSlot2 = -1;

    SubscriptionManager subManager = (SubscriptionManager) getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);

    if(subManager.getActiveSubscriptionInfoCount() >= 1) {
        mccSlot1 = subManager.getActiveSubscriptionInfo(0).getMcc();
        mncSlot1 = subManager.getActiveSubscriptionInfo(0).getMnc();
    }

    if(subManager.getActiveSubscriptionInfoCount() >= 2) {
        mccSlot2 = subManager.getActiveSubscriptionInfo(1).getMcc();
        mncSlot2 = subManager.getActiveSubscriptionInfo(1).getMnc();
    }

问题提到相同的 Android 限制。所以，我真的相信在 API22 之前使用纯 Android SDK 是不可能实现的。

Answer 2

        SubscriptionManager subManager = (SubscriptionManager) getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);
        List<SubscriptionInfo> subscriptionInfoList=new ArrayList<>();
        subscriptionInfoList=subManager.getActiveSubscriptionInfoList();
        Log.d("LIST LIST",subscriptionInfoList.toString());

日志是

SubscriptionManager subManager = (SubscriptionManager) getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);

    if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
            == PackageManager.PERMISSION_GRANTED) {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
            if (subManager.getActiveSubscriptionInfoCount() >= 1) {
                List<SubscriptionInfo> subscriptionInfoList;
                subscriptionInfoList=subManager.getActiveSubscriptionInfoList();
                mccSlot1 = subscriptionInfoList.get(0).getMcc();
                mncSlot1 = subscriptionInfoList.get(0).getMnc();
                Toast.makeText(this, "Sim slot 1 " + mccSlot1 + " " + mncSlot1, Toast.LENGTH_SHORT).show();
                mccSlot2 = subscriptionInfoList.get(1).getMcc();
                mncSlot2 = subscriptionInfoList.get(1).getMnc();
                Toast.makeText(this, "Sim slot 1 " + mccSlot2 + " " + mncSlot2, Toast.LENGTH_SHORT).show();

            }
        } else {
            TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
            if (telephonyManager == null) {
                return;
            }
            String mCCMncCode = telephonyManager.getNetworkOperator();
            String mccCode = null;
            String mncCode = null;
            if (TextUtils.isEmpty(mCCMncCode)) {
                return;
            }

            final int MNC_CODE_LENGTH = 3;
            if (mCCMncCode.length() >= MNC_CODE_LENGTH) {
                mccCode = mCCMncCode.substring(0, MNC_CODE_LENGTH);
            }

            if (mCCMncCode.length() > MNC_CODE_LENGTH) {
                mncCode = mCCMncCode.substring(MNC_CODE_LENGTH);
            }
            Toast.makeText(this, "Lower than API 22 " + mccCode + " " + mncCode, Toast.LENGTH_SHORT).show();
            return;
        }
    }
    else {
        ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_PHONE_STATE}, 1);
    }
