How to get carrier name from dual sim phone Android?

Question

I am able to get the carrier name from duel SIM phone.

I used the following code but it works only single SIM phone.

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

Answer 1

Fortunately there are several native solutions I've found while searching the way to get network operator.

For API >=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();
    } 
}

In AndroidManifest add permission:

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

To get network operator you can check mcc and mnc codes:

• https://en.wikipedia.org/wiki/Mobile_country_code (general information).
• https://clients.txtnation.com/hc/en-us/articles/218719768-MCCMNC-mobile-country-code-and-mobile-network-code-list- (quite full and quite latest list of operators).

For API >=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();
}

For API >=23. To just check if phone is dual/triple/many sim:

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

Using "SubscriptionManager" we can know the Carrier names of the dual sim of the android mobile.

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();

               }

            }
