Change Region in Settings auf Realme
The region on a realme phone is set once during initial setup, but it is not locked afterward. Many users assume changing it requires a factory reset, since it feels similar to language selection during onboarding. That is not the case - region is a standalone setting under Realme UI that can be changed anytime.
Region affects which store listings, weather sources, and some default apps appear on the device. It is separate from language and separate from time zone, so changing it will not reset your display language or your clock settings.
To change it, open Tap on Settings ➔ Tap on Additional settings ➔ Tap on Language & region ➔ Tap on Region ➔ Set the Region. Pick the correct country from the list and confirm.
After switching, some apps may need to be reopened or restarted before they reflect the new region. If an app store still shows the old country catalog, check whether that app has its own separate region setting, since some apps manage this independently from the system setting.
