In the following guide, Taimienphi will instruct you on how to change the Country Region for your App Store account.
For instance, if your App Store account is registered in Vietnam, you won't be able to search and download Google Maps. To download Google Maps, you need to use a US account. Therefore, we need to change the Country Region for your App Store account.
Step 1: On your iOS device, go to Settings > iTunes & App Store
Step 2: Tap on your account and select View Apple ID
Step 3: Enter your Password to confirm
Step 4: Select 'Country/Region' and modify the desired Country Region.
Note: If your account still has a balance (remaining credit), you cannot change the region. Apple will notify you to use up the remaining balance before the region change can be implemented.
