LTE modem?

Most of the cell modems (over the years) that I have seen show up as serial
devices and emulate a basic AT command set.  In most cases, you need to
know the dial string for your carrier --- it's often something goofball
like "ATDT pppservice.mycarrier.com" ... and then, after connecting
speaking ppp ... sometimes even without authentication.  The LTE modem I
picked up for my most recent laptop (and goes in an internal slot) fits
this bill.  IIRC, it shows up as a USB serial device.
