30 Days Unlimited 4G/5G Data Vietnam eSIM and Physical Card

Landing in Hanoi without mobile data can make the first hour harder than it needs to be. This service gives you unlimited high-speed data from Noi Bai International Airport, with a choice of eSIM or physical SIM and setup by airport staff.

I like the quick counter service, which has helped families set up four phones in just a few minutes. I also like the reported coverage across Hanoi, Hue, Da Nang, Ho Chi Minh City, and more remote areas, using Viettel’s network.

The main catch is simple: this is data only, with no voice calls or SMS. You also need to collect the physical card at Noi Bai if you choose that option, so it is less useful for anyone arriving at another Vietnamese airport.

Key points at a glance

• 30 days of unlimited data: Use 4G, LTE, or 5G without a stated data cap during the 30-day validity period.
• Pickup at Noi Bai Airport: Collect the card at the airport in Hanoi, with service available from midnight to 11:30 p.m.
• eSIM and physical SIM choices: The service supports eSIM, nano, micro, and mini SIM formats.
• Viettel network coverage: Strong signal has been reported across Hanoi, Hue, Da Nang, Ho Chi Minh City, and remote areas.
• Fast airport setup: Staff including Anna, Luong, Pham Diem My, Mai, and Thao have assisted with quick installation and activation.
• $13.80 price: The cost is attractive for a month of data, but less so if you only need a few days or want calls and texts.

Arriving at Noi Bai with data ready

The useful part of this service begins as soon as you reach Noi Bai International Airport. Instead of searching for a phone shop in central Hanoi, you collect your SIM at the airport and have it set up before heading into the city.

That timing matters. You may need maps, ride-hailing, hotel directions, translation tools, or a message to someone meeting you. Airport Wi-Fi can be useful, but it is not something I would want to rely on while handling luggage and figuring out your first ride.

The meeting point is Noi Bai International Airport in the Phú Cường area of Hanoi. The listed operating period runs from May 21, 2025, through February 16, 2027, with opening hours every day from 12:00 a.m. to 11:30 p.m.

Those hours cover most international arrival times. Still, check your booking details before flying, especially if your arrival is close to the stated closing time.

Choosing between eSIM and a physical SIM

You can select an eSIM or a physical card. The physical option includes nano, micro, and mini sizes, so older and newer phones are covered by the supplied formats.

An eSIM is handy because there is no tiny plastic card to remove or store. It can also let you keep your regular SIM in the phone, though the supplied information does not confirm how every handset handles dual-SIM use. Your device must support eSIM for that option, so check the phone specifications before booking.

The physical card is the safer choice if you are unsure about eSIM support. Staff at the airport can help with installation, and the setup process has been described as quick for both individual phones and family groups.

One practical point: the service says it is universally compatible with smartphone models, but you should still make sure your phone can connect to Vietnamese mobile networks. The exact device requirements are not provided, so checking before departure is sensible.

What unlimited data means in practice

The plan provides unlimited high-speed internet for 30 days. Speeds are listed as 4G, LTE, or 5G, depending on network availability and your phone.

That is a good fit for heavy data use. You can use maps throughout the day, upload photos, check transport information, make internet calls, and stay in touch through messaging apps without watching a small daily allowance disappear.

The word unlimited is valuable here, but it does not mean every connection will always run at 5G speed. Your signal will depend on the local Viettel network, your phone, and the area you are visiting. The service describes coverage as nationwide, and the plan has worked across major cities and more remote areas, but no mobile provider can promise identical speed in every place.

There is also no voice or SMS service. You can use WhatsApp, Messenger, email, and other internet-based tools, but you cannot rely on this SIM for ordinary mobile calls or text messages. If a hotel, driver, or tour company needs to call a Vietnamese number, this plan may not meet that need.

Viettel coverage from Hanoi to Ho Chi Minh City

The strongest reason to choose this plan is its stated Viettel network coverage. The service is designed to work throughout Vietnam, not only in Hanoi.

The connection has been used across Hanoi, Hue, Da Nang, and Ho Chi Minh City without reported coverage problems. That range matters if your itinerary includes several parts of the country rather than one city.

It has also handled more remote areas well. You should still expect the usual variation in mobile signal outside towns, but the supplied information points to reliable internet beyond the main urban centers.

For a long Vietnam trip, this is more convenient than buying a city-specific plan and replacing it halfway through your journey. You can move from northern Vietnam to the central coast and then south without arranging a new card each time.

The airport setup process

The counter service is meant to remove the fiddly part of using a foreign SIM. Staff can install the physical card or help with the eSIM, then get your mobile data working before you leave the airport.

Several staff names connected with the service include Pham Diem My, Luong, Anna, Mai, and Thao. Assistance has included setting up Samsung eSIM phones, activating several family SIMs, and explaining useful tips for staying connected.

That personal help is important if your phone menus are unfamiliar or you have never used an eSIM. The process is also useful for families, since four phones can be handled together rather than sending each person through a separate setup process.

The service promises trained staff, official SIM registration, and multilingual support. Vietnamese SIM registration rules can be confusing for a first-time visitor, so having an official airport setup is a practical advantage.

The main limitation is that this is still a counter-based pickup. You need to find the service at the airport and allow enough time for installation. It is not a card that is already active in your phone before you land.

24/7 support and flexible extensions

The provider offers 24/7 multilingual support. That gives you a contact point if the data does not work, you need help with settings, or you have a question after leaving Hanoi.

The plan also allows extensions through top-up or renewal. That is useful if your 30-day trip becomes longer, though the exact extension prices and methods are not provided here.

Do not assume that the plan includes a Vietnamese telephone number. The stated service type is data only, and top-ups or renewals relate to continued data access.

The money-back promise is another reassuring feature. The provider says you receive a full refund if the SIM does not work, subject to its stated terms. You should still test the connection at the airport before leaving the counter, when help is easiest to obtain.

Is $13.80 good value?

At $13.80 per person, the plan offers strong value for a full month of unlimited data. The price works out especially well for a 30-day trip, a family using several cards, or anyone who depends heavily on maps, messaging, and online bookings.

The airport pickup also has a value of its own. You are paying to avoid finding a shop in Hanoi, comparing unfamiliar data plans, and trying to explain your phone settings after a long flight.

The value is weaker for a short visit. If you are in Vietnam for only one to three days and spend most of your time at a hotel with Wi-Fi, 30 days of data may be more than you need. The supplied information mentions plans from 7 to 30 days, so ask about a shorter option if your itinerary does not justify a full month.

The lack of calls and SMS is the other factor to weigh. For app-based communication, the plan is well suited. For traditional calls, it is incomplete.

Who this SIM suits best

I would point this plan toward people who want to keep the first day simple. First-time visitors to Vietnam, families arriving together, and anyone moving through several cities should find the airport setup and nationwide coverage useful.

It also suits people who use a lot of data. If you plan to check maps often, upload photos, stream music, or make frequent internet calls, unlimited data removes the need to count gigabytes.

The eSIM option is a good match for supported phones and confident smartphone users. The physical SIM is better if you prefer a card you can hold, or if you want airport staff to handle installation.

I would be more cautious if you need a local number for calls and texts, arrive at an airport other than Noi Bai, or only need a tiny amount of data. In those cases, another option may suit you better.

What the airport location does and does not offer

This is a connectivity service, not a guided tour. There are no sightseeing stops, transfers, meals, or scheduled route through Hanoi. The activity begins and ends at the airport meeting point.

That makes the duration slightly different from a normal excursion. The plan lasts 30 days, but the airport visit itself should be a short setup stop. The exact time is not specified, though the service is intended to be fast.

The airport location is convenient if Hanoi is your entry point. It is not convenient if you arrive elsewhere or leave the airport before collecting the card.

The activity is near public transportation, and most people can participate. Service animals are allowed. These details matter mainly for visitors who need a simple airport pickup rather than a long organized activity.

Cancellation and booking details

You receive confirmation when you book. The ticket is mobile, so you can keep the booking on your phone and show it at the pickup point.

Cancellation is free up to 24 hours before the start time for a full refund. Cancellations or changes made within 24 hours are not accepted for a refund, and cut-off times use local Vietnamese time.

Since the product depends on an airport arrival, enter your flight information carefully if the booking form requests it. The supplied details do not state how long staff will wait for a delayed flight, so contacting support is wise if your plans change.

Should you book this Vietnam SIM?

Book it if you want 30 days of unlimited data, plan to visit more than one part of Vietnam, and will arrive through Noi Bai International Airport. The price is fair, the airport setup saves time, and Viettel coverage gives the plan a strong practical edge.

I would choose the physical card if you are unsure about eSIM support. I would choose the eSIM if your phone supports it and you want to keep your normal SIM available.

Skip it if you need calls or SMS, do not arrive in Hanoi, or only need a small amount of data. For everyone else, this is a sensible arrival-day purchase that gets you online quickly and keeps your phone useful across Vietnam.
