Can’t change my Apple ID country

Start here: Change your Apple ID country or region - Apple Support

Hey there,

its a simple way to change the country if mistakenly added wrong, and possible due to apple.

here is the method to change it,

Go to settings,

click on name which is visible on the top in settings,

click on media & purchases,

view account,

there you will get the option of country region,

select your correct country.

hope it might help.

cheers.
