(Since i do not speak polish, I've used translate.google.com)
The 5 field (the state of the SIM card)
0 - invalid SIM card or PIN code blocked
1 - normal SIM card
2 - SIM card not valid in CS mode
3 - SIM card not valid in PS mode
4 - SIM card not valid in PS or CS mode
255 - SIM not present 

The SIM is present, but still PIN code blocked.
The notify_sim_state function needs be changed.

pseudo code:
 If sim_state == 0 then 
   if 'AT+CPIN?' returns 'CPIN: SIM PIN' then
     sim_state = 'present but sim locked'
   else
     sim_state = 'invalid SIM'
   endif
 else if sim_state == 255 then
   sim_state = 'SIM not present'
 endif

I don't see any ^SIMST:1 or ^SYSINFO message.
