As title, if it is a single card mobile phone, I can know the recipient's phone number,

But if it is double card mobile phone, how should I get corresponding message recipient phone number, is that the recipient is card 1 or 2?

Is there a API can get?

This field is not accurate, now I see this field 6.0 the following machines, to 1,6.0 machines may be card slot ID and could be a real SIM card sub_id, when acquiring the call records also have sub_id, this ID also similarly is not accurate, very fan, just recently to do this, a little desperate
