Noi Bai Airport SIM Card (2026): Where to Buy & Price

If you are landing at Hanoi’s Noi Bai Airport (HAN) and searching for a SIM card, the short version is: yes, you can buy one in the arrivals hall, and it works, but the experience depends heavily on which desk you pick. This page sets out what is known, what travellers report, and what nobody has verified, so you can decide before you board.

---

The quick answer

• You can buy a local SIM at Noi Bai after you clear immigration and collect your bags. You need your passport.
• Prices at the counters are not published anywhere we could verify. Reports range from roughly 180,000 to 500,000 VND for a tourist package.
• The main risk travellers describe is not the price. It is buying a SIM that is not properly registered to you, which can be blocked later.
• If your phone supports eSIM, installing one before you fly avoids the counter altogether.

Where to buy a SIM card at Noi Bai Airport

Commercial guides and traveller reports put the SIM desks in the Terminal 2 international arrivals hall, after customs and baggage reclaim, near the exit. Viettel, VinaPhone and MobiFone are all reported to be present, but the guides disagree on exact positions, operators and opening hours, so we are not giving counter numbers or hours here.

One thing several guides repeat: alongside the carrier-branded desks, there are generic “taxi and SIM” stalls. Travellers say these sell pre-activated or “ghost” cards that carry a risk of being deactivated. The consistent advice is to walk past them and use a desk that is clearly an operator counter or an authorised store.

What we could not verify: how many counters are open today, which are run by the carrier directly and which by resellers, and their current hours.

Noi Bai airport SIM card price (reports, not a price list)

We have no dated photo of a price board and no receipt from Noi Bai. What exists are guide estimates and individual traveller reports:

Source type	What is reported
Commercial guides (2025–2026)	Roughly 185,000–500,000 VND for a tourist package, depending on carrier and length. The same guide pages are not consistent with each other.
One traveller (July 2025)	$18 for a 30-day VinaPhone SIM at Terminal 2.
One traveller (2026)	A cash-only purchase, apparently including a 50,000 VND SIM fee.

Guides also commonly say airport counters cost 30–50% more than city shops. We have not found a primary source for that figure, so read it as a rule of thumb that travellers repeat, not a measured fact.

If you buy at the counter, ask for the package code in writing, confirm whether the data is a daily cap or a total, and ask when the validity starts counting.

What travellers say: registration, queues and reviews

Vietnam requires prepaid SIMs to be registered with a passport, and counter staff typically photograph your passport and sometimes take your photo. Travellers describe the whole process as taking roughly 5 to 15 minutes once you reach the front, though we have no timed data for the queue after a long-haul arrival.

Several recent traveller threads warn that SIMs bought at airport booths were not registered in the buyer’s name, and later stopped working or caused problems. These are individual accounts, not proof that every booth does this. A sensible checklist at the counter:

1. Ask: “Is this registered to my passport?”
2. Ask the seller to show the number on your phone or send a test SMS.
3. Open a web page on mobile data before you walk away.
4. Ask for a receipt.

The alternative: an eSIM installed before you fly

A physical SIM works in any phone. An eSIM only works in an eSIM-capable one, but it skips the arrivals-hall step.

	Counter SIM at Noi Bai	Our Viettel eSIM
Phone needed	Any unlocked phone	eSIM-compatible phone
At the airport	Queue, passport photographed	Nothing to do
Registration	Done by counter staff	Set up by our supplier before you travel
Activation	Staff check it works	Automatic when your phone connects to Viettel
Phone number	Often included	Data only (see MobiFone below)
Price	Reported 180,000–500,000 VND	$9.90 (7 days) to $19.90 (30 days)

Our Vietnam eSIM runs on the Viettel network. Install it on home Wi-Fi, and when you land and your phone connects to Viettel it activates by itself, with no code to dial. The line is registered by our supplier, so there is no passport scan or selfie on your side. Validity starts on first connection, so installing early does not use up any days.

Plan	Data	Price
Viettel 7 days	35 GB (5 GB per day)	$9.90
Viettel 15 days	75 GB (5 GB per day)	$14.90
Viettel 30 days	150 GB (5 GB per day)	$19.90

When the high-speed allowance runs out, data stops. There is no slow-speed fallback on these plans.

Need a Vietnamese number? Our MobiFone plans differ: the 5-day (30 GB, $7.90) and 10-day (50 GB, $10.90) plans carry a real +84 number that receives calls and SMS for free, which is handy for hotel callbacks or verification codes. They are not active before landing: you dial 900 once after you arrive, and you can look up your number with *0#. The 11-day plan (38 GB, $9.90) includes 40 minutes of outbound local calls instead of a full number.

A note on eSIMs in general: a Viettel eSIM from a different provider can behave differently. Some users report that Viettel’s own tourist eSIM only completes activation once you are in Vietnam. If something does not connect, our eSIM not working in Vietnam guide walks through the fixes by symptom.

Which SIM card is best for tourists in Vietnam?

Viettel is the usual pick for coverage, and MobiFone for a local number. As for where to buy it:

• Choose the counter SIM if your phone has no eSIM, you want a physical backup SIM, or you prefer a person to check it works before you leave the hall. Pay attention to registration and the checklist above.
• Choose the eSIM if your phone supports it and you would rather land already connected, skipping the queue and the passport step.
• Choose a MobiFone eSIM if you need a local number that can receive calls and texts.

How we checked this

• Official source: our plan details come from our own catalog and supplier data (Viettel activation, MobiFone dial-900 step, *0# number check, plan allowances). Vietnamese SIM registration comes from the national rules.
• Reported, not verified: counter locations, operators, prices, hours, timings and payment methods at Noi Bai come from commercial guides and traveller threads (reviewed October 2026). We attribute them above and do not present them as fact.

What we couldn’t verify

• Current counter count, branding and hours at Noi Bai.
• Whether each desk is operated by the carrier or a reseller.
• A dated price board or receipt for any package.
• Queue length after a long-haul arrival, and the time from queue to working data.
• Accepted payment methods (cash, card, USD) as a rule.
