# CellularInfo 蜂窝网络数据

[简体中文 ➡️](https://github.com/DevelopCubeLab/CellularInfo/blob/main/README_Zh.md)

## Introduction

This app is a cellular network diagnostic and analysis tool for iOS, capable of querying over **160+** cellular network data points from CoreTelephony and underlying system frameworks.

The app provides detailed analysis of device information, SIM card information, carrier configurations (IPCC), radio access technologies (RAT), network status, and various low-level cellular parameters. By combining public system APIs with reverse-engineered private interfaces, the app is able to visualize data that is normally inaccessible on standard iOS devices.

The app also provides features such as IPCC management, IPCC compatibility checking, and network type configuration.

This project supports iOS **12.0 and later**, and is designed only for **iPhone and cellular-enabled iPad devices**.

Devices without cellular capability are not supported, including iPod Touch, Wi-Fi-only iPads, Xcode Simulators, and virtual machine environments (such as VPhone).

Jailbreak or TrollStore installation is required.  
Installing via a developer certificate provides access to only a limited subset of data.

This project will not support iOS versions below 12.0 because `CoreTelephonyClient` requires iOS 12.0+.

This tool is mainly intended for developers, security researchers, and advanced users who require deeper insight into iOS cellular network mechanisms.

To help protect your device data security, do not download installation packages for this project from unofficial sources, and do not share app data with others unless it is properly protected.

If you are interested in CoreTelephony, you can directly browse the organized source files below:

[`CoreTelephonyClient.h`](https://github.com/DevelopCubeLab/CellularInfo/blob/main/CellularInfo/Head/CoreTelephonyClient.h)  
[`CoreTelephonyController.swift`](https://github.com/DevelopCubeLab/CellularInfo/blob/main/CellularInfo/Controller/CoreTelephonyController.swift)  
[`CellularDataController.swift`](https://github.com/DevelopCubeLab/CellularInfo/blob/main/CellularInfo/Controller/CellularDataController.swift)

These files include status descriptions, comments, and documented error cases.

Most comments in the source code are written in Chinese, but you can easily translate them using translation tools or LLMs.

> [!NOTE]
> Some professional cellular network terms and technical details in this app may not be fully accurate, as certain areas are still being researched and verified.  
> If you are a telecom or networking professional and notice any incorrect information in the app, please feel free to submit an issue. Corrections and improvements are always welcome.

> [!WARNING]
> Due to the extensive use of private APIs in this project, testing may not cover every iOS version completely.  
> If you encounter crashes, error codes, or unexpected behavior, please provide the crash log (`.ips` file) and submit an issue.

## Installation

| System Version | Installation Method | Notes |
|----------|------|------|
| iOS 17.0+ devices without jailbreak support | Developer certificate sideloading ([limited data access](#10-Data accessible without extra entitlements)) | Can be installed using AltStore, SideStore, LiveContainer, LCSign, Esign, and other signing tools |
| iOS 17.0+ jailbreakable devices (A10 / A11) | Jailbreak + TrollStore Lite | - |
| iOS 14.0 - iOS 16.6.1 and iOS 17.0 | Install using TrollStore | - |
| iOS 12.2 - iOS 13.x | Jailbreak installation | Requires separate RootHelper installation |
| iOS 12.0 - iOS 12.1.x | Jailbreak installation | Requires an IPA compatible with iOS 12.0 and separate RootHelper installation |
