You land in Vietnam, clear immigration, and walk straight into a wall of SIM counters before you've even collected your bag. Staff wave you over, promising instant setup, but is that convenience worth what you'll pay for it?
At both Noi Bai (Hanoi) and Tan Son Nhat (Ho Chi Minh City), the counters look almost identical, and so does the markup. Before you join the queue, it's worth knowing what the counters actually charge and that a travel eSIM like Simju can be installed before you even board, so you land already connected
Where the Counters Are (and What You Get There)
-
Noi Bai Airport (Hanoi, HAN): SIM counters sit in the Terminal 2 arrival hall, just past customs, impossible to miss on your way to the exit.
-
Tan Son Nhat Airport (HCMC, SGN): two separate zones instead of one: a set of stalls inside international arrivals before baggage claim, and a second cluster outside near the exit gates.
-
Carriers at both airports: Viettel, Vinaphone, and Mobifone, each running its own branded booth.
-
What happens at the counter: staff take your phone, insert the SIM, and activate it on the spot without fumbling with settings yourself.
-
Package options: data-only or data plus calls, typically valid anywhere from 7 to 30 days depending on what you choose.
-
No extra paperwork: unlike SIMs bought elsewhere in the country, one purchased in person at these counters doesn't require separate registration; the vendor handles it as part of the sale.
Airport SIM Prices
-
Typical range: 250,000–400,000 VND (roughly $10–16) at both Hanoi and Ho Chi Minh City airports.
-
Real spread, same airport: one traveler paid 300,000 VND just past declaration, then saw the same package priced at 430,000 VND outside the terminal, proof that where you buy matters as much as which airport you're in.
-
Data value: around $10 gets you roughly 20GB at the airport, but that same $10 buys double the data once you're in the city.
-
The markup: airport pricing generally runs 30–50% higher than city shops or online eSIMs, with some sources putting the gap as high as 2–3× for certain packages.
| Location | Typical Price (VND) | Approx. Data | Notes |
|---|---|---|---|
| Noi Bai (Hanoi) | 250,000–400,000 | ~15–20GB | Single counter zone, just past customs |
| Tan Son Nhat — Inside Arrivals | ~300,000 | ~15–20GB | Before baggage claim, generally cheaper zone |
| Tan Son Nhat — Outside Terminal | ~430,000 | ~15–20GB | Same package, higher price for the same data |
eSIM Prices for Comparison
-
Vietnam travel eSIMs are affordable: Entry-level plans typically start around $5–6, while unlimited daily data plans generally range from $7–11 for 7 to 30 days.
-
Instant delivery: After payment, the eSIM QR code is delivered to your inbox within minutes, so there's no need to visit a store or wait in line.
-
Ready before you travel: You can install the eSIM before your flight, allowing you to connect as soon as you land without searching for a local SIM vendor.
-
Simju offers a simple setup: Vietnam eSIM plans are available at competitive entry-level prices, and the QR code is sent immediately after checkout.
-
Activation starts on arrival: The validity period begins only when the eSIM first connects to a supported network in Vietnam, so installing it before departure doesn't reduce your plan's duration.
-
Keep your primary number: Like most travel eSIMs, Simju provides a data-only service, allowing your physical SIM and home number to remain active for calls, SMS, WhatsApp, and iMessage.
-
Quick installation: The setup process takes about two minutes. Simply choose Vietnam, complete the purchase as a guest (no account required), install the eSIM before departure, and enable it as your primary data connection after landing.
Counter vs. eSIM, Side by Side
| Comparison | Airport Counter | eSIM |
|---|---|---|
| Price | 250,000–430,000 VND (~$10–17) | ~$5–11 |
| Setup Time | 10–20 min, on the spot | ~2 min, before you fly |
| Data Value | Lower per GB | Higher per GB |
| Passport / Registration | Required | None |
| Scam Risk | Present outside official zones | None |
| Calls / SMS | Yes, local number included | No — data-only |
| Top-up Flexibility | In person, on demand | Online, new plan or add-on |
The eSIM wins on cost and convenience: cheaper per GB, installed before you land, no passport copy, no line. The counter wins on flexibility; it works on any phone, gives you an instant local number for calls and SMS, and a staff member is right there if something goes wrong.
The main hesitation with eSIM is having no one to turn to if setup fails. Providers like Simju address that directly, with 24/7 human support and a 30-day money-back guarantee on unused eSIMs.
Scams to Watch For at the Counter
Airport SIM counters are generally safe, but not every vendor working the arrivals area is playing by the same rules. Here's what to watch for.
Not every SIM vendor near the arrivals hall is official.
Outside the designated counter zones, unlicensed sellers sometimes approach travelers directly, often with more aggressive pricing tactics than the branded booths inside.
The bigger risk isn't overpaying; it's getting a SIM that's already been activated or used before. These can work fine for a day or two, then get blocked by the carrier without warning, leaving you disconnected mid-trip with no easy fix.
Two habits avoid most of this
Buy only from official carrier-branded booths Viettel, Vinaphone, or Mobifone signage, not a loose vendor with a table. And before you walk away, test the SIM: make a call, load a page, confirm data is actually flowing. A working SIM at the counter takes ten seconds to verify.
Which Should You Choose?
-
Choose the counter if your phone isn't eSIM-compatible, you want a local number for calls and texts, or you're landing with nothing arranged and just need connectivity fast. The staff handles setup on the spot, and you walk away with a working number in minutes.
-
Choose eSIM if you want the best data value for your money, zero airport hassle, and you mainly need data for maps, messaging, and staying online, not a local phone number. Install it before you fly, and you're connected the moment you land, no queue involved.
-
There's also a hybrid option worth considering. Grab a small airport package, a counter SIM or a short eSIM plan just to get through the first day or two. Once you're settled, pick up a cheaper SIM in the city for the rest of a longer stay. You get the convenience of arriving connected without paying airport prices for weeks of data.
FAQs
Is it cheaper to buy a SIM in the city than at the airport?
Yes. Airport counters run 30–50% higher than the same SIM bought at a shop in Hanoi or Ho Chi Minh City, and city eSIM plans stretch further per gigabyte too. The airport premium buys convenience, not value. Pay it only for the first day or two, then switch if you're staying longer.
Can I use an eSIM in Vietnam if my phone isn't eSIM-capable?
No, eSIM requires a compatible device, and there's no workaround. Check your phone's settings or specs before you fly. If it's not eSIM-capable, a physical SIM from an airport counter or city shop is your only option.
Is Vietnam shutting down 2G?
Yes. The full 2G shutdown is set for September 15, 2026, only weeks away as of this writing. 2G-only handsets have already been barred from activating on Vietnamese networks since October 2024, so if your phone doesn't support 4G or VoLTE, it may lose service entirely once the shutdown hits.
Conclusion
Airport counters get you connected fast, but you pay for that speed; eSIM costs less and is ready the moment you land. Which one's right depends on how you travel: need a local number or a non-eSIM phone, go counter; want the best value with zero hassle, go eSIM.
If your phone supports it, installing Simju before your flight is the simplest way to skip the counter entirely and land already online.
