Another advantage is that most of these LTE modems allow me to connect an external antenna (a life saver when you have to have something in the middle of nowhere, and the tower is just on the other side of the ridge :D). There are devices that allow you to attach a USB LTE dongle (as opposed to having a built-in SIM slot), please make sure you get the manufacturer recommended dongle in those cases -- as otherwise "incompatibility" will waste your time. Just my 2p, hope this helps. All the best.
