For some reason that I fail to understand, all emails I've sent to any
@digi.com address over the past year have bounced back. I've even
tried with multiple email addresses, all get rejected. I hope you can
look at the mailing list archives to read this response, and if you
prefer, please use a different non-digi.com email address :)

I have no idea what those "modem sms-text" and "modem sms-binary"
things are :) They are not part of the ModemManager project, so I
assume those are some internal tools from Digi.
