Well the AT$NWRAT command might work…

I noticed that if I run the command with the verbose tag, the Mode Preference sent to the modem is ‘gsm, lte, td-scdma’. I think this causes problems since my modem doesn’t support td-scdma (--dms-get-capabilities shows only cdma20001x, evdo, gsm, umts, lte). I also noticed that whatever input I give to --nas-set-system-selection-preference, it seems to OR it with gsm, lte, and td-scdma. Is there a way to get --nas-set-system-selection-preference to only send ‘lte’ for the Mode Preference? I’ve copy/pasted results from my machine below.
