Hi Rafael,
as Vadim pointed out, you won't be able to do Authentication without the actual
auth tuples, which you most likely do not know for an arbitrary SIM.
In 2G however, it is possible to connect without Authentication. I think
that's done by 'auth-policy closed' and using 'ismi-acl add
<your-imsi>', in
the osmo-sgsn.cfg under 'sgsn'. Then you're not using the HLR at all.
In the MSC, we have added a configuration option 'authentication optional' so
that you can use the HLR and allow missing auth data there, but the SGSN hasn't
seen attention to that detail yet. There it's all or nothing, IIRC.
Looking forward to hear your results on it...
