Answer 1

SubscriptionManager can be used for it but its cannot be used third party apps by Android 10 and SubscriptionManager Added in API level 22

// Requires, android.permission.READ_PHONE_STATE
SubscriptionManager sm = SubscriptionManager.from(mContext);

// it returns a list with a SubscriptionInfo instance for each simcard
// there is other methods to retrieve SubscriptionInfos List<SubscriptionInfo> 
sis = sm.getActiveSubscriptionInfoList();

// getting first SubscriptionInfo
SubscriptionInfo si = sis.get(0);
