Balance 20x w/CAT 12 (R) Module in an RV

Hello, I have been reading through this forum and googling for most of today. I just purchased an RV that unknown to me had a Balance 20x with the cat 12 module (XM-MINI-1LTEA-R) thrown into a cabinet (not factory install). There is an antenna as well but I can not find any markings to know what it is. I am very bad understanding technology so I apologize with my “dumb” questions. Reading this forum you all seem to be very computer-literate! Questions:

  1. Is there a way to connect to my StarLink via WIFI or do I need to connect it via ethernet only?
  2. If Im reading everything right, this hardware will only support 4G/LTE SIM cards? IS that Right or can it use a 5G SIM card?
  3. Any other pointers would be much appreciated
    Thanks All!
  1. I’d use eithernet for starlink
  2. this is not a 5g device but a 5g sim card may work just giving you 4g/lte
  3. like what?
