Try this and see if you can get the error again:

qmicli -v -p -d /dev/cdc-wdm1 --wds-start-network=3gpp-profile=1,ip-type=4 --client-no-release-cid
qmicli -v -p -d /dev/cdc-wdm1 --wds-start-network=3gpp-profile=1,ip-type=6 --client-no-release-cid

and if for some reason that doens't work, make do:

qmicli -v -p -d /dev/cdc-wdm1 --wds-start-network=3gpp-profile=1,ip-type=4 --client-no-release-cid
qmicli -v -p -d /dev/cdc-wdm1 --wds-start-network=3gpp-profile=2,ip-type=6 --client-no-release-cid

(eg, swap the V6 request to profile #2)

We've never been able to figure out what PolicyMismatch actually is,
but perhaps the firmware doesn't like something about the specific
attributes during the start call, when it would be happier if we just
pointed it to one of the existing profiles and it could use those.

Another thought, perhaps the default bearer is already activated, and
attempting to activate another bearer conflicts with the default bearer
options or something.  But lets figure that out later.
