How can I change Vietnam App Store to another country App Store ,I ' m very bore of this incident and upset of Apple service shop because can't help me changing to Thailand App Store,help me ,please

Basically you will have to create a new Apple ID for every store i.e. one ID per country-specific store. You will also need a credit card (or iTunes gift card) from the relevant country for payment (so for the free stuff, you are all set).

It's a bit of a hassle but you can sign in and out of the App store in order to download/update apps to your device(s).

This is certainly another option (which I considered). However, the OP *might* lose access to previously purchased apps/products (see below)...

Redownload any past purchases that you want to keep on your device. Your Purchased section no longer shows items that you purchased from the store in the previous country or region. You won't be able to update these apps or content without downloading or purchasing them again in your new country or region. Additionally, if you use iCloud Music Library, the content in your library won't appear in your library after you change your country or region.

You can only change the AppleID associated with the iTunes, App or iBook stores on any given device once every 90 days. So if you sign in with AppleID-1 and then sign out and sign in with AppleID-2, you cannot sign back in with AppleID-1 again until 90 days has passed.

See the bottom of View and remove your associated devices in iTunes - Apple Support

Change your iTunes Store, iBooks Store, or App Store country or region: https://support.apple.com/en-ca/HT201389

You cannot change store just to get apps from a different country.

You can only download apps in your country where you live have billing address in that country.

You have to be physically in that country.

If you sign in with an apple id created in Thailand, it should take you to the Thailand app store.
