A SIM card explorer refers to the combination of hardware (a smart card reader) and software used to navigate, view, and modify the internal file system of a SIM card. No standard command returns all files under a DF

No standard command returns all files under a DF. The Explorer must maintain a lookup table of known EF IDs (from 51.011, 31.102, 102 221) and optionally attempt to SELECT from 0x0000 to 0xFFFF. This brute force can lock cards if too many failed SELECTs occur. Use known file ID ranges and only SELECT with p2=0x0C (return FCI, no data) to avoid triggering security logic.
