There is something wrong with your modem... Sorry to say. The Verizon USB551L doesnt support neither GSM nor UMTS. :-(
There are two known ways to get/set rat...
The NAS set selection preference methinks is be uses when to choose between CDMA and GSM.
I will check this up when I have the source code at hand.

> I am using qmicli with a Novatel USB551L modem. When I try to use the --nas-set-system-selection-preference command to set my preference to ‘lte’, I get a ‘DeviceUnsupported’ error. 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.
