Hello Rafael,
sorry that it took me some time to answer, I was on holiday.

This is expected if you have set the default access mode to "none"
(something like "subscriber-create-on-demand 5 none" in osmo-hlr.cfg).
The new subscriber was created, but a location update request fails
because it is not allowed to access the (circuit or packet switched)
network:
https://git.osmocom.org/osmo-hlr/tree/src/hlr.c?id=28f0774e341c3dbe1045ca61…
And after giving "cs+ps" permission, when
trying to set to "none" again,
I get:

This looks like a bug. I've pasted your report here (please extend if
you have more details):
https://osmocom.org/issues/4163
Anyway, in it is working as expected! I'll
investigate the logs further.
There is a word missing, but it seems that for the most part it is
working as expected? ;)
Thanks for the feedback!
Cheers,
Oliver

Hello Rafael,
you're welcome. I've just merged the new VTY command and manuals update
to master:
https://gerrit.osmocom.org/q/topic:subscr-on-demand-manual
So if you rebuild your osmo-hlr packages from master, you should have
the command (if I understood correctly that you are building the
packages yourself, otherwise it will be in the nightly packages tomorrow).
After a subscriber has been created on demand, with network access mode
set to "none", you can give the subscriber access to circuit and packet
switched services as follows:
OsmoHLR> enable
OsmoHLR# subscriber imei 35761300444848 show
ID: 1
IMSI: 123456789023000
MSISDN: 58192
IMEI: 35761300444848
CS disabled
PS disabled
OsmoHLR# subscriber imei 35761300444848 update network-access-mode cs+ps
OsmoHLR# subscriber imei 35761300444848 show
ID: 1
IMSI: 123456789023000
MSISDN: 58192
IMEI: 35761300444848
Cheers,
Oliver

Thanks a lot, Oliver!
The VTY commands for changing nam_cs and nam_ps will be useful.
; )
Any problems I let you know!
