Answer 1

Since API version 22 its possible

try following code for device having os greater than android 5.1

List<SubscriptionInfo> subscriptionInfos = SubscriptionManager.from(getApplicationContext()).getActiveSubscriptionInfoList();
for(int i=0; i<subscriptionInfos.size();i++)
{
    SubscriptionInfo lsuSubscriptionInfo = subscriptionInfos.get(i);
    Log.d(TAG, "getNumber "+ lsuSubscriptionInfo.getNumber());
    Log.d(TAG, "network name : "+ lsuSubscriptionInfo.getCarrierName());
    Log.d(TAG, "getCountryIso "+ lsuSubscriptionInfo.getCountryIso());
}

for more information : Documentation: SubscriptionManager - Android Hope it helps. Peace.
