Does Verizon know if I switch the 4G sim into another phone?

    Can carriers tell what device you are using when you just switch the sim card. For example, if you take a Galaxy S3 sim, and cut it down to iPhone 5 size and use it with the 5, would the website reflect that you are on an iPhone 5 or still a Galaxy because the IMEI registered with the account would not change, but the service is on the SIM and that would change.

    Yes Verizon knows exactly what device u are using at any time

    But Verizon cannot do anything about LTE sim switching per FCC rules.

    I have had my LTE sim From Verizon galaxy nexus in my Verizon LTE iPad since march. And Verizon knows about it but they cannot disable my data.

    So free unlimited data on my iPad along with free unlimited LTE hotspot.

    LTE sim switching is good.

    They know yes and if they could they would tie you up and hang you upside down in a dungeon while beating you savagely with spiked baseball bats but due to the FCC they can't.

    They can tell from the IMEI number on your phone.
