How to read the other party's mobile phone number after receiving the short message from I message?

I can't see the other party's number, but I can only see the other party's apple ID, but when sending a message, it is set to send a short message when I message is not available, and the mobile phone number is displayed. This is the only way. Is invisible. Another way is that you turn off your I message function, even if the other party's function is turned on, it can only be a short message and you can see the number. Because this function will only be displayed as I message if both I message functions are turned on, I hope it can help you.
