So you're really limiting the scanning for networks only to when the
modem is already connected to a given network which is not LTE. I don't
think we shouldn't ban from scanning when access tech is UNKNOWN.
Also, the reply to AT+COPS=? may really take a loong time; you sure it
gets stuck?
I wonder how the scan works when the Novatel LTE modem is handled by the
QMI driver. IIRC Dan said we wouldn't need this specific plugin any more
once the modem is handled by the QMI implementation.
