I’ve done this as a project to go from 3G to LTE for a network of a few hundred devices.

3G and LTE (4G) used almost identical AT commands. The motherboards were build so the modems were swappable. It wasn’t too bad. I’m told the field techs had to drive 5 hours across the Australian outback to access some of them.
