Tan Son Nhat International Airport (SGN) in Ho Chi Minh City handles more international arrivals than any other airport in Vietnam. The moment you clear immigration, you will be hit by a long wall of SIM card kiosks.
The question isn’t where to find them, but which counter to trust and how to avoid getting ripped off. This Tan Son Nhat Airport SIM Card guide covers what is actually at the airport, how much it costs, and when it makes more sense to skip the airport entirely.
I. Can You Get a SIM at Tan Son Nhat Airport?
Yes. There are exactly two distinct zones in SGN airport where SIM cards are sold:
1. Before immigration (1F – 1st floor)
Several stalls are located inside the international arrival area, before you collect luggage and clear customs. These are generally legitimate and competitively priced.
Stalls here have higher security oversight, more consistent pricing, and zero aggressive vendors. It’s best if you want to land with active data immediately.
2. After Customs (GF – Ground floor)
Once you exit through A1 or A2 into the main arrival hall, you will see a long row of shops (number 1-15). These sell SIM cards alongside tour packages, currency exchange, and transport bookings. This zone is loud, highly competitive, and has the highest price markups.
⚠️The Layout Trap: The official, carrier-branded Viettel and MobiFone counters are at the far left end of this walkway. You will have to walk past several aggressive reseller stalls first, so do not stop until you reach the very end.
Both zones sell legitimate SIMs from the major operators; the difference is price and pressure.
II. Which Carriers Are Available at SGN airport?
All three major Vietnam mobile operators – Viettel, Vinaphone, MobiFone – have official kiosks here:
- Viettel: Best nationwide coverage, strongest in rural areas and mountainous regions. Best choice if your trip includes anywhere outside major cities.
- Vinaphone: Strong urban speeds, now with Southeast Asia’s top-ranked 5G network. Good for city-focused trips. Tourist SIM includes a local phone number and international call minutes.
- MobiFone: Solid urban performance. Also available via the Hi Vietnam app with eKYC registration for large data packages.
For most tourists arriving at Tan Son Nhat who’ll be in HCMC and the surrounding region, any of the three works. For trips heading to Da Lat, Mekong Delta, or beyond, Viettel is the safer option.

IV. Buying a SIM at Tan Son Nhat Airport: Step-by-Step Guide
1. What to bring
- Passport (original — required by law for registration)
- Cash in VND or USD (most counters accept both; some take Visa/Mastercard but cash is more reliable)
- Your unlocked phone
► Do they ask for photo and passport at airport SIM counters in Vietnam?
2. The Process
- Choose a carrier counter — Viettel, Vinaphone, or MobiFone
- Tell staffs your needs (staying duration, mainly needs – data only or calls)
- Ask to see the plan options — most counters have printed menus or tablets showing plans
- Present passport for registration – takes 1–2 minutes
- Staff inserts the SIM and configures your phone
- Test the Apps: Open Grab and try to register before leaving the counter to ensure the number isn’t blacklisted.
- Dial
*101#or*098#to display your actual +84 phone number
3. Opening hours
Most SIM counters operate from 6:00 AM to 10:00–11:00 PM.
⏰ Late-Night Arrivals: Some stay open later for late-night arrivals. If you arrive after midnight, you may still find one or two counters open – but it is not guaranteed.
A better alternative for physical SIM cards is a Vietnam eSIM set up before your flight. This is a reliable option for very late arrivals.
V. Airport SIM Scams to Watch Out For
Travel forums (Reddit/Facebook) are packed with warnings about airport SIMs. Here are 4 realistic things to watch out for:
1. Pre-activated SIMs
Some kiosks at Tan Son Nhat sell SIM cards activated days (or weeks) before your purchase, cutting into your validity period. Always ask the seller to verify the activation status before paying.
2. Used Numbers (The Grab Nightmare)
Airport stalls frequently sell recycled numbers. Many travelers report being unable to register for Grab, Zalo, or Shopee because the number was already blacklisted by a previous owner.
3. Passport Misuse (High Risk)
A traveler on Reddit whose passport was used to register an additional SIM card without their knowledge — discovered only when they went to an official Viettel store to troubleshoot. Official stores can disconnect unauthorized SIMs from your passport, but it’s a hassle you don’t want mid-trip.
4. Aggressive Resellers
Right outside the sliding doors after baggage claim, resellers actively direct travelers to shops in the main hall — they’re working together and often push overpriced packages. Walk away and choose your own counter.
How to protect youself from airport scams:
- Buy before immigration when possible.
- Walk to the far end of the row to reach official Viettel/MobiFone counters – don’t stop at the first stalls calling out to you.
- Stick to single-brand official kiosks rather than multi-brand resellers.
- Always test the SIM — confirm data is working and (if applicable) you can receive a call — before leaving the counter.
- Pre-order via SASCO online and pick up at the airport.
- Choose a Vietnam eSIM before your flight for a total piece of mind.
VI. Should You Buy at the Airport or Wait?
Buy at SGN Airport if: You are on a short trip (3–5 days), need a working Grab car immediately, or arrive during normal daytime hours. The convenience outweighs the $5–$10 markup.
Wait for the City if: You are staying in Vietnam for weeks, need an absolutely clean number for local banking/Zalo apps, or want the ultra-cheap local 5G data packages.
Note: If you choose to wait for buying at the city stores and use free WiFi at the airport instead, note that multiple travelers report it’s unreliable or unavailable at times. Don’t count on it as a guaranteed fallback for good connectivity.
VII. eSIM – Alternative to Physical SIM at SGN Airport
If your phone supports eSIM, buying online before your flight offers you instant connection upon arrival in Ho Chi Minh City airport – no counters, no passport, no testing whether the SIM works. The single disadvantage is that it works on esim-compatible devices only.

VIII. What You Need the SIM For After Landing
Most travelers landing at Tan Son Nhat need connectivity for three things immediately:
- Grab: The ride-hailing app that gets you from the airport to your hotel without negotiating with taxi drivers. You can register Grab with your home number before departure; in-app chat handles driver communication without a Vietnamese number. However, getting a local number helps if a driver calls. → Read more: Grab, Xanh SM & Be in Vietnam: Which App to Use?
- Google Maps: Works on mobile data. Download the HCMC offline map before you land as a backup for areas with poor signal.
- Hotel confirmation / WhatsApp: Most hotels and guesthouses respond on WhatsApp, which runs on data — no local number needed.
Buying a SIM at Tan Son Nhat is convenient and gets you connected immediately. The stalls are legitimate, but you’ll pay 2–3x city prices for the same data. For a short trip, that premium is usually worth the convenience. For longer stays, buy at the airport to get through day one, then switch to a better-value plan at a city store.
For the cleanest experience, you should get a Viettel or Vinaphone or MobiFone eSIM before you fly. There, you will land with instant connection, skip the counters entirely.
