In the early days of Windows Phone development, Vietnam lacked its own app region format for selection. Consequently, our app store couldn't match the variety found in the US or Singapore.
Thankfully, you can still download and install apps not tailored for Vietnam by changing your device's region settings directly on your Windows Phone. It's just a little effort.
Here's how you can change your region settings to download apps on Windows Phone:
Step 1: Go to Settings > Language + region from the Menu screen.
Step 2: Select the Region format, and you'll see a list of countries to choose from. You can opt for the United States since it supports most apps.
Step 3: After selecting the desired region format, restart your device.

Tap Restart phone to complete the setup.
Changing your region format for app downloads also grants you access to top-rated apps popular in that country. You might discover many apps and games that suit your preferences from around the world.
