OK, so you got some errors counted. That's interesting because it means
that was some packet on the link.  Could you enable a few debugging
messages and see if any of them are triggered?

Something like this might do (or maybe do too much - adjust as
necessary...):

 echo 'module cdc_ncm +fp' >/sys/kernel/debug/dynamic_debug/control
 echo 'module usbnet +fp' >/sys/kernel/debug/dynamic_debug/control
 ethtool -s wwan0 msglvl rx_err on
