Contact with multiple cell phones. iOS 7. How to see which phone number. used?

Question

iPhone

We are talking about how you can understand to which number I send SMS, from which number I received SMS.
In the correspondence I see only the name of the contact and that's it.
Thanks in advance!
PS
iMessage is disabled
In android it was obvious. I can't understand here.

You must click on the "Contact" button to the right of the contact name. In the menu that appears, click on the rightmost information button (i). The contact details will appear, the used number will be highlighted in blue. (iOS 7)
