SIM Country Spoofer is a root module that rewrites common Android SIM and operator country properties during the boot process. It allows users to easily change their Mobile Country Code, Network Code, ISO, and carrier name to bypass basic region checks.

I've been running this on my daily driver to test region-restricted services. It handles the basic property overrides surprisingly well under the hood, and while it won't fool heavy apps checking GPS or IP data, having a visual WebUI to swap between fake carriers like T-Mobile or NTT DOCOMO is incredibly handy.

Core Features

Spoofs system properties like gsm.sim.operator.numeric and iso-country automatically during boot.
A visual interface built for KsuWebUIStandalone lets you edit carrier identities without touching a text editor.
Full dual-SIM compatibility easily handles comma-separated properties for devices with two active slots.
Persistent boot application ensures the spoofed values are forcefully reapplied shortly after Android fully starts up.

Support & Requirements

Root: Magisk, Magisk Alpha, or KernelSU
Requirements: KsuWebUIStandalone (optional, but required for the WebUI feature)

How to Install

Download the latest module .zip file from the GitHub releases page.
Flash the file through your Magisk or KernelSU manager app.
Reboot your device to activate the default US/T-Mobile configuration.
