Top 3 Best eSIMs Recommendations for Vietnam

Choosing the best eSIM in Vietnam depends on your data needs and the duration of stay.

1. Viettel (Best Coverage)
Viettel is the largest state-owned provider. If you need a Vietnam eSIM with a phone number, Viettel is the gold standard for signal strength in rural areas like Sapa or Ha Giang.

2. Vinaphone / Mobifone (Urban Reliability)
Excellent for city dwellers in Ho Chi Minh City or Hanoi. Many travelers find these offer the best eSIM for Vietnam from Australia and Europe due to competitive pricing and easy remote registration.

3. Airalo / Holafly (Global Aggregators)
For those who want a Vietnam unlimited data eSIM, aggregators like Holafly offer "fixed-price, unlimited data" packages, though they typically do not include a local phone number.

Vietnam eSIM With Local Phone Number (+84): What You Need to Know

Most international eSIM providers sell data-only plans. For many tourists, this is perfectly adequate — WhatsApp, FaceTime, and Google Maps work without a local number.

However, a Vietnamese phone number (+84) makes certain tasks significantly easier for tourists:

Grab and Gojek (ride-hailing): Drivers frequently call to confirm pickup locations. Without a number, communication is limited to the in-app chat, which can be slow.

Restaurant and hotel reservations: Many local businesses in Vietnam still accept bookings by phone or Zalo (Vietnam’s primary messaging app) rather than via the app.

Some local apps, such as Zalo, work more smoothly with a Vietnamese phone number, especially for long-term stays.

OTP verification: Banking apps, MoMo (digital wallet), and Shopee all require OTP delivery to a local number. Registering for services as a longer-term visitor: Any local app that requires a Vietnamese phone verification.

Coverage & Speed: 5G vs. 4G

Major cities such as Hanoi, Ho Chi Minh City, and Da Nang generally offer strong 4G and expanding 5G coverage, depending on your provider and device.

Rural Regions: If you are trekking in Ha Giang or the Mekong Delta, Viettel is widely considered the strongest option for rural coverage, especially in areas like Ha Giang and the Mekong Delta.

Remote Islands: 5G is now available on Phu Quoc and Con Dao, making them perfect for digital nomads.

Where to Buy a Vietnam eSIM

• Airports: Viettel kiosks at Noi Bai (Hanoi), Tan Son Nhat (Ho Chi Minh City), Da Nang, Cam Ranh, Phu Quoc.
• Official Stores: Viettel, VinaPhone, and Mobifone outlets across major cities.
• Online Providers: International eSIM platforms like Airalo, Holafly, and Saily allow purchase before arrival.

Step-by-Step: How to Use Your eSIM in Vietnam

1. Purchase & Install: Pre-Departure

• Check compatibility at provider sites (e.g., scan QR test).
• Buy your eSIM and receive a QR via email/app while you still have stable Wi-Fi.
• Before flight: Settings > Cellular > Add eSIM > Scan QR (iOS) or + (Android).
• Do not delete the profile once scanned, as most codes are single-use.

2. Activate the Line: Upon Landing

Once you touch down at Tan Son Nhat, Noi Bai, or Da Nang airport, toggle eSIM on, select your data line, and enable roaming/data.

3. Set Default Data: Configuration

Select the Vietnam eSIM as your Primary Data Line. Crucially, turn off home SIM roaming to avoid charges from using your expensive home SIM.

Activation is usually quick once the eSIM profile is installed and connected to a supported network. Hotspot allowed on most.

Pricing Comparison (USD): Finding the Cheapest eSIM Vietnam

• Budget (Local Carriers): $5 - $10 USD for 10GB–30GB (usually requires passport registration).
• Mid-Range (Travel Apps): $15 - $25 USD for 20GB–50GB.
• Premium (Unlimited): $30+ USD for unlimited data packages (ideal for heavy video streaming).

Pro Tip: Airport SIMs are convenient, but prices are often higher than online eSIM plans. They often carry a 2x markup compared to online eSIM prices and may use "recycled" numbers that trigger spam calls.

Tips for Tourists

Short Trips (under 7 days): Choose Viettel’s 5G60T or an international eSIM for convenience.

Longer Stays (15–30 days): Viettel’s 5G150T or 5G180H offers the best value.

Multi-country Travel (Vietnam + Cambodia): Consider Airalo or Holafly for regional coverage.

Unlimited Data Needs: Holafly’s unlimited plan is ideal for heavy users.

Vietnam eSIM for Cambodia (and Regional Southeast Asia Plans)

If Vietnam is one stop on a broader Southeast Asia itinerary that includes Cambodia, Thailand, or Laos, a regional eSIM eliminates the need to buy a separate plan for each country.

Airalo offers the Asialink plan, which is well-suited for multi-country trips across Vietnam, Cambodia, and Thailand. The plan provides data across all three countries without requiring a plan switch at each border.

Other regional options to consider:

• Holafly operates in multiple Southeast Asian countries and maintains consistent speed across borders — useful for overland travelers crossing from Vietnam into Cambodia via the Mộc Bài or Xa Mát border crossings.
• GigSky is particularly well-suited to frequent border crossers, tending to maintain more stable connections when users move frequently between different areas or cross borders during the same trip.
• Airalo's Asia regional plan also covers additional countries, including South Korea and Japan, making it a strong choice for longer multi-country itineraries.
• When evaluating regional plans, check whether Cambodia's network partners are included — Metfone and Smart Axiata are the dominant carriers there, and not all regional eSIM plans include both.

Pro Tips for Using eSIM in Vietnam

Coverage: Viettel generally offers the widest reach, including remote areas like Ha Giang or the Mekong Delta.

Unlimited Data Caution: Many "unlimited" plans have high-speed caps before slowing down.

Hotspot: Most plans allow tethering — confirm with your provider.

Safety: Use trusted providers to avoid scams. Download maps offline as backup.

Buy eSIM for Vietnam: Always compare current deals on official sites, as promotions change frequently.

Common Mistakes When Using an eSIM in Vietnam

Installing too early
Some plans — particularly Viettel-based ones — start their validity countdown the moment the eSIM activates or first connects to the network. Install the profile on your device whenever you like, but do not turn the eSIM line on until you land.

Not setting the eSIM as the default data line
After installation, your phone defaults to your home SIM for data. Go into settings and explicitly set your Vietnam eSIM as the data line. Otherwise, your home SIM roaming charges will accumulate in the background.

Ignoring "Allow Cellular Data Switching."
On iPhones, this setting allows the phone to automatically switch data between SIM lines. Turn it off for your home SIM to avoid unexpected roaming charges.

Buying based on price alone
When it comes to Vietnam eSIMs, price is not the most important factor — the network operator is. A cheap eSIM running on a weaker network costs you more in frustration than the dollars saved.

Not accounting for "unlimited" throttling
As covered above, read the daily speed cap before purchasing any unlimited plan.

Frequently Asked Questions

Can I get a Vietnam eSIM with a phone number?
Most international travel eSIMs for Vietnam are data-only and don't include a local number. GIGAGO is currently the primary exception, offering a local Vietnamese number alongside data on domestic network access.

Can I use my Vietnam eSIM as a hotspot?
It depends on the provider. Holafly caps hotspot at 500 MB per day. Saily includes a hotspot on all plans without speed caps. Airalo's hotspot support varies by specific plan. Always confirm before purchasing if tethering is a priority.

How do I activate an eSIM in Vietnam?
Install the eSIM via QR code before departure (requires Wi-Fi). Upon landing in Vietnam, go to cellular settings, set the eSIM as your default data line, and enable Data Roaming on that line.

Can I use a Vietnam eSIM and a Cambodia eSIM on the same trip?
Yes, either by purchasing a regional Southeast Asia plan that covers both countries, or by installing two separate eSIM profiles on your phone. Most phones allow multiple eSIM profiles, but only one is active at a time — you switch between them in settings at each border.

Is it safe to delete my Vietnam eSIM profile?
Only delete it when you're certain you no longer need it. Most providers issue a QR code valid for one-time use — if deleted, you'll need to contact support for a replacement code.

Is an eSIM better than a physical SIM for Vietnam?
For convenience — yes. For cost, a local physical SIM from Viettel or Vinaphone is slightly cheaper. The right choice depends on how much you value arriving already connected versus saving a small amount at the airport counter.

Final Verdict: Which Vietnam eSIM Should You Buy?

Travelers who prioritize rural coverage usually prefer Viettel-based plans, while regional eSIMs are more convenient for multi-country trips across Southeast Asia.

Vietnam offers affordable, fast, and reliable eSIM options for tourists. Purchase before departure, install the QR code, and activate the moment you land—no passport, no queue, no hassle.
