otherwise the SMS should not be processed further.
The SIM applet registers a timer with min_sleep_time from the SMS. When the
timer triggers, the IMSI of the SIM is overwritten with the new pseudonymous
IMSI, the TMSI and GSM Ciphering key Kc (3GPP TS 31.102, Section 4.4.3.1) are
invalidated. The current imsi_pseudo_i from the SMS is stored in the SIM applet
timer triggers, EF~IMSI~ of the SIM is overwritten with the new pseudonymous
IMSI. The TMSI and related data (EF~LOCI~, EF~PSLOCI~) and ciphering keys
(EF~Kc~, EF~KcGPRS~, EF~Keys~, EF~KeysPS~) are invalidated (see 3GPP TS
31.102). The current imsi_pseudo_i from the SMS is stored in the SIM applet
to compare it with the next SMS. imsi_pseudo_lu is reset to 0. Afterwards,
the EF~IMSI~ changing procedure in 3GPP TS 11.14, Section 6.4.7.1 is executed
to apply the new IMSI.
