Updated about 4 years ago.
Description
Even after a SIM REFRESH with SIM Init, the SIM still uses the previous TMSI.
Find out how the SIM applet can forget the TMSI or use an invalid one.
- Status changed from New to In Progress

We can update "EFLOCI (Location Information)", which consists of (3GPP TS 31.102, 4.2.17):
- Temporary Mobile Subscriber Identity (TMSI);
- Location Area Information (LAI);
- Location update status.
- Status changed from In Progress to Resolved
- % Done changed from 0 to 100
Patches added to invalidate the TMSI, TMSIGPRS, KC and KCGPRS.
I've verified with wireshark, that the SIM now directly sends the IMSI instead of trying the TMSI.
