The`content://`style URL for this table. Used for APN query based on current subscription. Instead of specifying carrier matching information in the selection, this API will return all matching APNs from current subscription carrier and queries will be applied on top of that. If there is no match for MVNO (Mobile Virtual Network Operator) APNs, return APNs from its MNO (based on mccmnc) instead. For MSIM, this will return APNs for the default subscription[SubscriptionManager.getDefaultSubscriptionId()](https://developer.android.com/reference/android/telephony/SubscriptionManager#getDefaultSubscriptionId()). To specify subId for MSIM, use[Uri.withAppendedPath(Uri, String)](https://developer.android.com/reference/android/net/Uri#withAppendedPath(android.net.Uri,%20java.lang.String))to append with subscription id.
