Which network should I pick for the best coverage: Viettel, Vinaphone, or Skyfi?

Viettel is Vietnam's largest mobile network by coverage and subscriber base, a strong default if your trip includes rural or mountainous areas like Sapa or Ha Giang.
Vinaphone and Skyfi (MobiFone MVNO) also offer solid nationwide coverage and are good options if you want a local phone number included.

What Customers Say About Gigago eSIM?

Over 1,000,000 customers have experienced and are satisfied.

I traveled through 7 countries in Europe in just 15 days, and Gigago eSIM was a lifesaver! Instead of buying multiple SIM cards, I had one eSIM that worked seamlessly in France, Germany, Italy, and beyond. The local network support meant I had 5G speeds in major cities, which made navigation, video calls, and social media uploads effortless. Saved over $100 on roaming fees!

James T.

Great purchase! No regrets in choosing eSIM from Gigago. It was convenient, easy to set up and reliable. I was skeptical at first, but after using Gigago eSIM in Japan, I’m convinced this is the best way to stay connected while traveling. The prices are much cheaper than my carrier’s roaming fees - only over $35 for a 30-day trip with 20GB of high-speed data. Highly recommend this for budget-conscious travelers!

I had trouble installing the eSIM on my Samsung Galaxy S22, but Gigago’s customer support was amazing. I contacted them via live chat at midnight, and they responded in less than 2 minutes! They walked me through the steps, and within 5 minutes, I was connected to 4G LTE in Thailand. I didn’t have to stress about data limits, and the connection was fast and stable everywhere in Bangkok, even in crowded areas like Chatuchak Market and the Grand Palace.

I used Gigago eSIM for a 10-day adventure in Indonesia, and overall, it worked great. The internet was fast in Jakarta and Bali, but when I visited Komodo Island, the signal dropped to 3G. If you’re staying in cities, Gigago is perfect, but for rural areas, expect some fluctuations.

Sophie M.

Germany

As a digital nomad, I need fast and reliable internet. I used Gigago's unlimited eSIM in Vietnam for a full month and had 99% uptime! I worked remotely, joined Zoom meetings without lag, and even streamed Netflix in HD. Plus, I could share data with my laptop without any issues. This eSIM is a must-have for remote workers!

Lucas R.

Singapore

When I was in Paris, I realized that many restaurants and taxi services only accept local phone numbers for reservations. Thanks to Gigago’s France eSIM, I had a French number, which made it easy to book tables at popular restaurants and call local taxis without using expensive international calls. If you're traveling in France, this is a must-have!

Frequently Asked Questions

Answer common questions about Vietnam eSIM as well as Gigago eSIM.

Do I need a passport to buy the eSIM?

It is not necessary to show your passport when buying eSIMs at Gigago.com.

When does my Gigago eSIM start?

The activation time depends on the network provider for your chosen plan:
– Viettel plans: Your eSIM service begins as soon as you scan the QR code and activate it on your device. We recommend scanning and installing the QR code only one day before your trip or upon arrival in Vietnam to make the most of your validity period.
– Vinaphone plans: Your eSIM service starts automatically when your device connects to the local network for the first time.
– Skyfi (MobiFone MVNO): Your eSIM starts upon arrival in Vietnam and connect to the Skyfi network.
– Local/MobiFone plans: Your eSIM service starts from the moment you press the Activate button in the eSIM QR code link or follow the sent activation guide.
This ensures your plan’s validity period begins exactly when you’re ready to use it.

Does the eSIM come with a phone number?

Yes, the plans covered by Vinaphone (for receiving only) and Local/MobiFone come with a phone number while the ones covered by Viettel and Skyfi do not.

Can I make phone calls or send texts using Vietnam eSIM?

It depends on the plan you choose. Gigago Local/MobiFone’s eSIM plans offer phone number while Vinaphone’s (also having number but for receiving only), Viettel’s and Skyfi do not. With all plans, you can make a call and send text messages via apps like Skype, WhatsApp, Telegram, etc. using the mobile data available in the eSIM plan.

Can I share Internet using Vietnam eSIM?

Yes. You can use hotspot/tethering feature with a Gigago eSIM for Vietnam.

What phone supports eSIM?

To know which mobile devices support eSIM, please read our full list of eSIM-compatible devices.

How to install an eSIM?

After payment, you will receive an email that includes a QR code and user guide for installation on phones. Then, you just need to follow the guidelines and you are all set to go. See details: How to install eSIM.

Do I have to turn on my eSIM data roaming?

Yes, you are required to do so to get the best coverage. This will not incur any additional fees, as long as you have already set up the Gigago eSIM.

What happens if I use up my data or my days of validity?

If your data has been used up or your eSIM validity comes to an end, your eSIM card will no longer work and you will not be able to connect to the internet. If you want more data, buying a new plan is the best choice.

When should I set up my eSIM for Vietnam?

As you need Wi-Fi to set up your eSIM, we recommend that you install your eSIM before departure. And then, activate your eSIM data plan when you land in your destination.

How many times can I scan the eSIM QR code?

The QR code can only be scanned once. If you encounter any issue during the installation and activation of your eSIM, please do not delete the eSIM. Instead, contact GIGAGO at email: [email protected] or Hotline (WhatsApp): +1 657-571-1199.

How early can I buy the eSIM?

The eSIM plan covered by Viettel should be bought no more than 15 days before the intended date of use while the others (covered by Vinaphone and Local/Skyfi/MobiFone) are for 30 days, so you can buy it in advance and keep it in your email for up to 15-30 days (depending on the chosen plan). However, do not purchase eSIM too early, as the QR code will expire after this period.

Can I use the included Vietnam phone number to verify apps like Zalo or my banking app?

Not necessarily. The included Vietnam number is not guaranteed to work for app registration or verification purposes (e.g. Zalo, banking apps), since it’s a prepaid tourist eSIM rather than a fully registered local line.

Which mobile networks does the Vietnam eSIM use, and is coverage reliable nationwide?

Gigago’s Vietnam eSIM runs on Viettel, Vinaphone, and Skyfi (a MobiFone MVNO) – Vietnam’s leading domestic carriers – giving you genuine local network access (not international roaming) for better speed and stability in Hanoi, Ho Chi Minh City, Danang, Nha Trang, Sapa, and nationwide.

Do I need to keep my original SIM card, or will I lose my current number?

No, you keep your primary SIM in your phone and continue to receive calls, SMS, and bank verification codes as normal, while the eSIM handles your data (and local number, if included) in Vietnam.

Do I really need an eSIM for Vietnam, or can I rely on public Wi-Fi and buy a SIM locally?

Public Wi-Fi in Vietnam is common in cafes and hotels but isn’t reliable once you’re out sightseeing or need maps and ride-hailing apps on the go. A physical SIM bought informally also carries the registration risk mentioned above. An eSIM bought in advance solves both – it’s ready the moment you land, with no store visit or registration step needed for our data-only plans.
