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.
