Nrfr is a root-free Android tool that changes the SIM card country code by calling native system APIs (CarrierConfigLoader) with Shizuku permission support. It helps fix carrier configuration mismatches, roaming compatibility issues, and region-locked apps like TikTok and Samsung Health.

Use cases

change SIM country code without root
fix TikTok region restriction errors
pass Samsung Health SIM region check
fix carrier config mismatch while roaming abroad
make an overseas SIM card behave like a local one
unlock carrier-specific features on Android
fix apps detecting the wrong SIM region

When to choose

you need to change SIM country code on Android without root or Xposed/Magisk
you have Shizuku set up and want a reversible, system-API-based solution
you need per-SIM (dual SIM) country code configuration that survives reboot

When to avoid

you cannot or do not want to install Shizuku
you need to actually rewrite the SIM card itself
you are on a non-Android platform or Android below 8
