Buying Guide – How to Choose the Best Esim Card for Vietnam
Selecting the right connectivity plan depends on trip length data needs and device compatibility.
Data Allowance
Most options offer either fixed high-speed data or unlimited plans with throttling. Consider your usage habits like streaming versus navigation to choose the right cap.
Select a plan with enough high-speed data to cover your daily needs without interruption.
Validity Period
Plans range from 15 days to 365 days so match the validity to your trip duration. Longer validity helps if you plan multiple visits or return trips.
Ensure the plan covers your entire stay so you do not need to buy another card.
Network Speed
Look for 5G support to ensure fast speeds in major cities like Hanoi or Ho Chi Minh City. Some plans throttle after high speed usage which affects performance.
Confirm the card supports 5G/4G LTE for the best browsing and navigation experience.
Device Compatibility
Ensure your phone is unlocked and supports the required network types. Some options do not work with specific devices like Google Pixel models.
Check device specs before buying to avoid activation issues once you arrive.
Physical vs Digital
Physical SIMs arrive by mail while eSIMs provide QR codes instantly. Digital options are faster to set up but require an eSIM-capable device.
Choose physical if your phone lacks eSIM support and digital for immediate activation.
Hotspot Support
Some plans allow hotspot sharing which connects multiple devices like tablets or laptops. Check if this feature is supported if you travel with others.
Verify hotspot capabilities to ensure you can share data across all your devices.
Activation Method
Plans may require website activation upon arrival or work immediately upon insertion. Some eSIMs activate automatically when connecting to a local network.
Follow setup instructions carefully to ensure you get connected right away.
Multi-Country Coverage
If visiting other Asian nations select a plan that includes those destinations. Some options cover 10+ countries for seamless travel across borders.
Choose a multi-country plan to avoid buying separate SIMs for every stop.
How to Use and Care for Your Esim Card for Vietnam
Install the physical SIM by powering off your device and inserting it into the tray. For eSIM scan the QR code and follow prompts to add the cellular plan in settings.
Enable data roaming and local data settings once in Vietnam to activate the plan. Wait a few minutes for the network to connect and verify signal bars appear.
Keep your SIM safe in its original case to avoid bending or damaging the chip. Contact support if activation fails or network issues arise during your trip.
Frequently Asked Questions
Does the Vietnam esim include a phone number for calls?
Most data plans do not include a phone number and focus on internet access. You can make calls using apps like WhatsApp or Line via the data connection.

Once you reach the high-speed limit the plan throttles to slower speeds for basic tasks. Unlimited data continues at reduced speeds so messaging and email still work.

How do I activate the SIM when I land?
Insert the SIM and turn on data roaming settings. For eSIM scan the QR code and follow the activation steps before or upon arrival.
Are these plans refillable if I run out of data?

Will the SIM work on phones locked to carriers?
No operator locked or regional locked devices are not supported. Ensure your phone is factory unlocked for compatibility.
