I just activated my new iPhone XS. Loving it, by the way. 
So I'm looking at all the small little things that's new. In the Settings app, in the section ABOUT, it lists my Serial number and IMEI. Below that, there is another entry called "Second SIM", which shows me a different IMEI number. What is that?
