You can use SubscriptionManager to get the list of active subscriptions: https://developer.android.com/reference/android/telephony/SubscriptionManager.html#getActiveSubscriptionInfoList()

To get the default SMS subscription ID you can use this API in SmsManager: http://developer.android.com/reference/android/telephony/SmsManager.html#getDefaultSmsSubscriptionId()
