* The assumption here is that if sim manager is being initialized,

* then sim commands are implemented, and the sim manager is then
|
|
* responsible for checking the PIN, reading the IMSI and signaling
|
|
* SIM ready condition.
|
|
*
|
|
* The procedure according to 31.102 is roughly:
|
|
* Read EFecc
|
|
* Read EFli and EFpl
|
|
* SIM Pin check
|
|
* Read EFust
|
|
* Read EFest
|
|
* Read IMSI
|
|
*
|
|
* At this point we signal the SIM ready condition and allow
|
|
* arbitrary files to be written or read, assuming their presence
|
|
* in the EFust
