You can bring your Gmail and Outlook to Vietnam and use them as you do at home, both sync over Wi-Fi or mobile data, and you don’t need a VPN. What needs a little preparation is signing in, because Google and Microsoft may ask you to verify a login from a new place, and a text code sent to your home number doesn’t always arrive abroad.
In this article, we answer “Does Gmail & Outlook Work in Vietnam?” in practical terms: what to set up before you fly, how to keep getting codes on your home number with a Vietnam eSIM, and what to do if your inbox won’t load or sign in.
Are Gmail and Outlook blocked in Vietnam?
No. Gmail and Outlook are accessible in Vietnam. You can use their mobile apps or websites to read, send and sync emails over Wi-Fi or mobile data without a VPN.
OONI network tests conducted in Vietnam between January and October 2026 found no confirmed blocking of Gmail or Outlook. The tests covered major networks, including Viettel, VNPT and FPT, although results may vary across networks and connections.
If you use a work or school email account through Google Workspace or Microsoft 365, check with your IT team before traveling. Your organization may have separate rules for signing in from abroad.
- Set up Microsoft Authenticator. You can use its verification codes offline, although approval notifications require an internet connection.
- Set up a passkey if available for your account.
- Save your Microsoft account recovery code somewhere safe.
For work or school email:
- Ask your IT team whether you can access your account from Vietnam, whether you need a company VPN and which verification methods are available.
On your phone:
- Keep Gmail and Outlook signed in throughout your trip.
- Avoid deleting and reinstalling the apps unless necessary, as you may need to sign in and verify your identity again.
Can you still get codes on your home number with a Vietnam SIM or eSIM?
Yes. You can receive verification codes on your home number while using a Vietnam eSIM for mobile data, provided your phone supports dual SIM, your home SIM remains active and your carrier supports receiving SMS in Vietnam.
On a dual-SIM phone, set your Vietnam eSIM as the mobile data line and keep your home SIM for calls and text messages. Turn off data roaming on your home SIM to avoid unexpected data charges. Check with your carrier about international roaming and SMS charges before departure.
If you remove your home SIM or it cannot receive SMS abroad, codes sent to that number will not reach you. This is why setting up an authenticator app and saving backup codes before traveling is important.
Avoid changing your account recovery number to a Vietnamese number just for a short trip. The phone number included with our Vietnam eSIM plans is not guaranteed to work for app registration or verification.
If you want to keep receiving messages on your home number while using mobile data in Vietnam, a data-only Vietnam eSIM can work well with this setup. See our guides on using your home SIM and a Vietnam eSIM at the same time and turning on data roaming when you land.
What should you do if Gmail or Outlook won’t load or sign in?
First, check whether your internet connection works by opening another website. If other websites load normally but Gmail or Outlook will not let you sign in, the issue may be related to account verification rather than your connection.
- Neither Gmail nor other websites load: Switch between Wi-Fi and mobile data. If you’re using an eSIM, check that it is activated and selected as your mobile data line. See our Vietnam eSIM troubleshooting guide.
- The verification code doesn’t arrive: Try another available method, such as an authenticator app, Google prompt or backup code. Avoid repeatedly requesting new codes.
- You cannot access your account: Use Google’s account recovery page or Microsoft’s account recovery form. Submit the request from a device you have used to sign in before, if possible.
Why is my Gmail or Outlook showing Vietnamese?
Your Gmail or Outlook interface may appear in Vietnamese because of the language settings in your account, app or device. Being in Vietnam does not automatically mean your email language has to change.
To switch back to English:
- Outlook.com or new Outlook: Go to Settings > General > Language and time.
- Classic Outlook for Windows: Go to File > Options > Language.
- Gmail on a computer: Open Settings > See all settings > Language.
- Gmail on a phone: Check your device’s app language settings. On recent Android versions, this is usually under System > Languages > App languages. On iPhone, Gmail may follow the language settings configured for the app or device.
Conclusion
Gmail and Outlook work in Vietnam without a VPN, so you can stay on top of your emails throughout your trip. The main thing to prepare is account verification, especially if Google or Microsoft asks for a code sent to your home phone number.
Before you fly, check your recovery details, set up an alternative verification method and keep your home SIM active if you need to receive SMS codes. You can then use a Vietnam eSIM for mobile data while keeping your regular number available for important messages.
