Fortunately there are several native solutions.
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:
For newest devices you can use newest APIs.
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
}
