Would you be able to add the "-v" flag to qmicli and copy in the full
QMI request/response data that it prints out?

I'm not sure it'll show much useful but it would allow us to double-
check what qmicli is sending to the modem.

One thing to try is that perhaps the modem doesn't like the "all"
access technology option and doesn't know how to handle it. Could you
try explicitly listing them, like "22802,gsm|umts|lte"?
