Modern SIMs follow the UICC concept (ETSI TS 102 221). They contain one or more file systems:

A: No. The phone number associated with your SIM is a network-level binding, not a changeable file stored on the card. You cannot modify it with any explorer tool.

Think of it like this:

Forensic Analysis and File System Architecture Exploration via SIM Explorer Tools. Abstract: This paper investigates the utility of SIM Explorer tools in digital forensics and mobile network research. It examines the hierarchical file structure of 2G/3G/5G SIM cards, the methods of data extraction using APDU commands, and the efficacy of these tools in recovering evidentiary data such as deleted SMS and contact records. 2. Core Concepts: SIM Card Architecture

The SIM Card Explorer is not merely a tool; it is a paradigm shift in how we treat the SIM card – from a sealed black box to an auditable file system. By providing structured, graphical, and safe access to the UICC's contents, it empowers forensic analysts, security researchers, IoT developers, and advanced users. However, with great power comes great responsibility. The community must adopt strong ethical guidelines to prevent misuse. We release the proposed architecture under a dual-license model: GPLv3 for non-commercial research, and a commercial license for forensic labs with built-in access logging.

In the digital age, we handle our smartphones every day, yet few of us ever stop to think about the tiny piece of plastic that makes the entire device functional: the . It is smaller than a postage stamp, but it holds the keys to your digital identity—your phone number, contacts, text messages, and network authentication keys.

A popular commercial tool designed for deep analysis of GSM, 3G, and LTE SIM cards. It features an intuitive tree-view graphical interface of the file system.

SIM explorers are critical tools for a variety of professional and enthusiast use cases:
