Good To Know

- Affordable Price: At just $3.22 per person, this eSIM provides excellent value considering its 30-day duration.
- High Compatibility: Works with eSIM-compatible devices not locked to a local carrier; check your device before purchasing.
- Global Coverage: Supports major networks in Vietnam and over 200 countries, making it ideal for multi-destination trips.
- Data Management: Offers both daily reset and fixed plans, with reduced speeds after high-speed data is used.
- No Refunds: Once purchased, the eSIM isn’t refundable or cancellable—make sure your plans are firm.

Overview of the Experience
Setting up the Hanoi Data eSIM is refreshingly simple. After purchase, most travelers receive their QR code within minutes—perfect for last-minute plans or those arriving unexpectedly. According to the provider, you just scan the QR code, and your device will automatically configure the eSIM profile. Since the plan starts immediately upon installation, it’s wise to confirm your travel dates before activating.
This eSIM’s focus is purely on mobile data, with speeds up to 4G LTE or 5G depending on local network availability. For many, that might be enough to navigate Hanoi’s busy streets, upload photos, or stream music during quiet moments. It’s a solid option if you primarily rely on internet-based communication apps like WhatsApp or Messenger, as most reviews highlight the ease of messaging even after the high-speed data pool is exhausted.

Detailed Breakdown of the Data Plans

The eSIM provides a range of options to suit different usage patterns. You can choose a plan that resets every 24 hours, or a fixed plan with a set high-speed data allowance. After exceeding your allotted high-speed data, the plan shifts to a reduced speed of 128 kbps, which is still enough for messaging apps but not ideal for streaming or video calls.
Travelers can expect unlimited data at reduced speeds after their high-speed cap is used up. This is a practical feature for those who want to stay connected without constantly monitoring their data use. The daily reset option is particularly convenient for those with unpredictable data needs—perhaps on days with more sightseeing versus days with less.
Compatibility and Device Considerations

This eSIM is compatible with devices that support eSIM technology and are not carrier-locked. If you’re traveling with an iPhone XR or newer, or a recent Samsung Galaxy, chances are good you’ll be able to use it without issues. However, most devices bought in China or Hong Kong may not support eSIM, so it’s worth checking online or asking your provider.
You’ll want to ensure your device can activate the QR code without problems—some reviewers mentioned difficulty with old or incompatible devices. The setup process is straightforward but double-check your device’s compatibility beforehand.
Coverage and Network Quality

The eSIM claims to connect to major local networks at 4G LTE or 5G speeds, depending on what’s available in Hanoi. Most reviews indicate stable, fast connections that support browsing, messaging, and even some streaming. Since it supports hotspots, you can share your internet with other devices or friends if needed, which adds an extra layer of convenience.
Coverage spans not only Hanoi but also major airports and various regions across the city, ensuring you’re connected whether you’re exploring the Old Quarter or heading out to less central areas.
Price and Value Analysis

At just $3.22 per person for 30 days, this eSIM offers remarkable value. For less than the cost of a coffee in many cafes, you get enough data to last your entire stay—assuming moderate use. It’s especially attractive compared to local SIM options, which might require more complex setup or higher prices for similar data packages.
However, bear in mind this is data only—if you need to make calls or send SMS, you’ll need a separate plan. For most travelers who mainly rely on WhatsApp, Facebook Messenger, or Google Maps, this isn’t a big deal.
The one-time prepaid setup means no hidden costs or auto-renewals, making it easy to control your budget. Just be aware that, according to the provider, no refunds or cancellations are available once purchased, so double-check your travel plans beforehand.

Who Should Consider This eSIM?
