@aentinger @pennam can you please review ?

I think it would be better to add a specific enum for subfrequency band here https://github.com/arduino-libraries/MKRWAN/blob/5cc2f53395ffd7fdaabc213471dc08d37f2aa96c/src/MKRWAN.h#L262-L267 to be used as function argument

LGTM 👍 Please have a look at the comments for details.

One general question: Do we really need all those get-methods? In general I prefer to keep any API as small as possible without compromising functionality. Looks to me like all those getters mainly serve debugging purposes during development?
