SIM/SAT simulator (Soft SIM)

simLAB supports USIM/ISIM card simulation and SIM application toolkit (SAT). SIM file-system is saved in ./sim_soft/sim_backup.xml. To backup live SIM filesystem use shell command backup.

When registering in Network Simulator use dummy xor authentication algorithm. Security codes are configured in ./sim/sim_codes.py

SAT simulation

simLAB implements basic SAT functionality useful for testing SAT features from UE perspective.

• terminal profile (hardcoded)
• setup menu list
• display text
• refresh with modes:
  • SIM init and full file list notification
  • SIM init and file list notification
  • SIM reset
• SAT initiated USSD code

Some of the SAT commands like refresh might be triggered with shell command sat

Limitation

• 2G SIM support is limited.
• SFI is not implemented
• SQN validation is not implemented in dummy XOR authentication
• Milenage authentication is not implemented
