If there were a mobile IoT device needing only a low data rate and not needing low latency, would NB-IoT be a good connectivity option? Would LTE-M be better?

‘Mobile’ is key here. A device that will physically move many kilometres.

(Assuming both LTE-M and NB-IoT were available in the relevant geographies, and that the module to be deployed would support only one of NB-IoT or LTE-M.)

I’ve seen statements that LTE-M is better for mobile applications, but I can’t find info on why it would be better in the situation described above.

  • $\begingroup$ Radio access wise, LTE-M is designed with smaller latency and, therefore, is better suited for applications requiring mobility. There are also assumptions and implementations at protocol levels, e.g. only cell reselection for NB-IoT. Just search for "3GPP eMTC applications". $\endgroup$
