Hi Rafael,

Please pay your attention at the following warnings:

> hlr.c:79 250026920931392: IMSI known, but has no auth data;
> Returning slightly inaccurate cause 'IMSI Unknown' via GSUP

and

> sgsn_auth.c:236 MM(250026920931392/e550701e)
> Missing auth tuples, authorization not possible
> sgsn_auth.c:248 MM(250026920931392/e550701e)
> Got authorization update: state unknown -> rejected

Are you sure you do have all required auth information in HLR?

> IMSI 250 02 6920931392

BTW: is it a random IMSI? Otherwise, this IMSI belongs to a
Russian carrier - Megafon. If I am correct, and this SIM is
a commercial SIM, you won't be able to get the auth data for them.

With best regards,
Vadim Yanitskiy.
