Question

我可以从决斗SIM手机中获取运营商名称。

我使用了以下代码，但它仅适用于单个SIM卡手机。

TelephonyManager telephonyManager = ((TelephonyManager) mContext.getSystemService(Context.TELEPHONY_SERVICE));

Answer 1

幸运的是，在搜索获取网络运营商的方式时，我发现了几种原生解决方案。

对于API＆gt; = 17：

TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);

// Get information about all radio modules on device board
// and check what you need by calling #getCellIdentity.

final List<CellInfo> allCellInfo = manager.getAllCellInfo();
for (CellInfo cellInfo : allCellInfo) {
    if (cellInfo instanceof CellInfoGsm) {
        CellIdentityGsm cellIdentity = ((CellInfoGsm) cellInfo).getCellIdentity();
        //TODO Use cellIdentity to check MCC/MNC code, for instance.
    } else if (cellInfo instanceof CellInfoWcdma) {
        CellIdentityWcdma cellIdentity = ((CellInfoWcdma) cellInfo).getCellIdentity();
    } else if (cellInfo instanceof CellInfoLte) {
        CellIdentityLte cellIdentity = ((CellInfoLte) cellInfo).getCellIdentity();
    } else if (cellInfo instanceof CellInfoCdma) {
        CellIdentityCdma cellIdentity = ((CellInfoCdma) cellInfo).getCellIdentity();
    } 
}

在AndroidManifest中添加权限：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
</manifest>

要获得网络运营商，您可以查看mcc和mnc代码：

https://clients.txtnation.com/hc/en-us/articles/218719768-MCCMNC-mobile-country-code-and-mobile-network-code-list-（相当完整且最新的运营商名单）。

对于API＆gt; = 22：

final SubscriptionManager subscriptionManager = SubscriptionManager.from(context);
final List<SubscriptionInfo> activeSubscriptionInfoList = subscriptionManager.getActiveSubscriptionInfoList();
for (SubscriptionInfo subscriptionInfo : activeSubscriptionInfoList) {
    final CharSequence carrierName = subscriptionInfo.getCarrierName();
    final CharSequence displayName = subscriptionInfo.getDisplayName();
    final int mcc = subscriptionInfo.getMcc();
    final int mnc = subscriptionInfo.getMnc();
    final String subscriptionInfoNumber = subscriptionInfo.getNumber();
}

对于API＆gt; = 23。要检查手机是双/三/多SIM卡：

TelephonyManager manager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
if (manager.getPhoneCount() == 2) {
    // Dual sim
}

Answer 2

使用＆＃34; SubscriptionManager＆＃34;我们可以知道Android手机双卡的运营商名称。

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

            List<SubscriptionInfo> subscriptionInfoList=subscriptionManager.getActiveSubscriptionInfoList();

            if(subscriptionInfoList!=null && subscriptionInfoList.size()>0){
               for(SubscriptionInfo info:subscriptionInfoList){
                  String carrierName = info.getCarrierName().toString();
                   String mobileNo=info.getNumber();
                   String countyIso=info.getCountryIso();
                   int dataRoaming=info.getDataRoaming();

               }

            }

Answer 3

由于android并不支持至少低于API级别22的多个sim。

从API 22开始，您可以使用SubscriptionManager的方法getActiveSubscriptionInfoList（）检查多个SIM。有关https://developer.android.com/reference/android/telephony/SubscriptionManager.html#getActiveSubscriptionInfoList%28%29的更多详情。
