Not really, no. LTE is 3GPP, so the LE866-SV is 3GPP, regardless of
operator, we cannot change that or it wouldn't work in MM. What we
need is a way to "switch to 3GPP2 SMS messaging" in 3GPP-only modems,
either automagically (maybe flagging this specific modem to do so via
a udev tag) or via a user-requested option when creating the SMS.

Is the modem locked to Verizon in any way?
