I was actually looking at these:
https://nimbelink.com/skywire-cellular-modem-lte/
They seem to have multiple modems 2g, 3g, 4g, and the one in the link has a TNAG which has fallback from lte all the way back to 2g. My problem is that I have no idea how I would actually communicate with this? Would I just open the serial port and send AT commands or would the sim900 library in theory work for this modem as well?
