How to get Operator Name for SIM in slave slot?

Question

For dual SIM device how to getNetworkOperatorName which is in slave slot. And my master SIM is deactivated.

Answer 1

I didn't find anything on android API to get all SIM operators details. Only we can get the name of the Current Network Operator or SIM operator

TelephonyManager telephonyManager =((TelephonyManager) Context.getSystemService(Context.TELEPHONY_SERVICE));
String operatorName = telephonyManager.getNetworkOperatorName();

SIM operator can be retrieved by using:

String operatorName = telephonyManager.getSimOperatorName();

Answer 2

You need to use SubscriptionManager's getActiveSubscriptionInfoList() https://developer.android.com/reference/android/telephony/SubscriptionManager.html#getActiveSubscriptionInfoList()

However, keep in mind that it was only added in API Level 22
