What a Vietnam SIM Card Costs Indians in 2026
For a 7-10 day trip, plan on roughly ₹479 (~130,000 VND or ~$4.97) for a tourist pack from any of the three big networks. At current rates (1 INR = 268 VND), that works out to about ₹450, which is the standard “tourist SIM” everyone quotes.
Three carriers matter to you: Viettel, Mobifone, and Vinaphone. All three run near-identical tourist SIM offers at airports. Viettel has the widest 4G/LTE coverage in rural areas (Sapa, Phong Nha, Ha Giang loop), so most travellers I have spoken to default to Viettel.
Subodh’s Pro Tip: Buy your SIM at the airport even if you have read that city shops are cheaper. Airport kiosks charge a small premium, but you walk out with a working line in five minutes, which matters when you need Grab to your hotel at midnight. If you buy in the city, you must show your passport at a Viettel/Mobifone store, and the staff often push daily tourist packages on you.
Where to Stay and SIM Logistics
Where to Buy on Arrival in Hanoi or Ho Chi Minh City
At Noi Bai International Airport (Hanoi) and Tan Son Nhat International Airport (Ho Chi Minh City), you will find SIM kiosks in the arrivals hall. The official network counters (Viettel, Mobifone, Vinaphone) sit right after immigration. The process takes about 5-10 minutes:
- Hand over your passport (they will photocopy it and register your SIM).
- State your stay length in days (7, 10, 15, or 30).
- Pay in VND (cash) or by card.
- They insert the SIM and test data on the spot.
- You walk out with a local Vietnamese phone number + roughly 6GB of data for ₹479 (~130,000 VND or ~$4.97).
If you arrive late and the official network counters have closed, look for third-party resellers like “Viettel Store” branded booths in the arrivals area; they charge the same ₹479 (~130,000 VND or ~$4.97) for the standard tourist pack.
Subodh’s Pro Tip: Ask the staff to set up data + a working hotspot before you leave the counter. Most travellers leave with data working but no APN configured (this rarely happens in 2026 since staff set it up by default, but if your phone is locked to a non-standard APN, just ask).
The Three Networks: Which One to Pick
All three carriers sell near-identical tourist packs. Coverage is the real differentiator.
| Network | Tourist Pack (7-10 days) | Strength | Weakness |
|---|---|---|---|
| Viettel | ₹479 (~130,000 VND or ~$4.97) | Best rural/remote coverage (Sapa, Ha Giang, Phong Nha) | Slightly slower 4G in dense city centres |
| Mobifone | ₹479 (~130,000 VND or ~$4.97) | Fast in HCMC/Hanoi/da Nang | Patchier in the north |
| Vinaphone | ₹479 (~130,000 VND or ~$4.97) | Decent nationwide, often slightly cheaper promo | Customer service can be slow |
For most Indian travellers doing the standard Hanoi → Ha Long Bay → Ninh Binh → Hoi An → Da Nang → Ho Chi Minh City route, Viettel is the safe pick. If your trip is mostly urban and southern, Mobifone is fine.
What You Get for ₹479 (~130,000 VND or ~$4.97)
The standard tourist pack includes:
- A local Vietnamese phone number (starts with 09, 03, or 08).
- Roughly 6GB of high-speed 4G/LTE data, valid 7 days.
- After 6GB, data throttles to 256kbps (still usable for WhatsApp and Google Maps).
- Free domestic calls within Vietnam (usually 30-50 minutes, network-dependent).
- No international calls included (you use WhatsApp, FaceTime, or Telegram for that).
If you need more data or a longer validity, top-up is cheap. Most networks sell a 1-day unlimited pass for ₹37-₹55 (~10,000-15,000 VND or ~$0.38-$0.57) or a 7-day unlimited pass for ₹184-₹280 (~50,000-75,000 VND or ~$1.91-$2.86).
Safety Alert: Do not throw away the SIM card holder. It contains your phone number and the customer-service hotline. If you lose your phone or SIM, you need that number to block the line and recover it.
eSIM Options for Indian Travelers
If your phone supports eSIM (most phones bought in India after 2022 do, including iPhone 11 onwards and Samsung Galaxy S20 onwards), you can skip the physical SIM entirely and buy a Vietnam eSIM before you land.
Two popular eSIM providers that work in Vietnam:
- Airalo: “Asialink” Vietnam plan, 5GB / 30 days, around ₹1,542 (~16 USD)
- Nomad eSIM: Vietnam plans starting from 1GB / 7 days around ₹482 (~5 USD) up to 10GB / 30 days around ₹2,410 (~25 USD)
For travellers who want data ready the moment they land at Noi Bai or Tan Son Nhat, eSIM is the cleanest option. The activation is QR-code based, you scan it before leaving India, and the line activates when you reach Vietnamese soil. Get Nomad eSIM is the eSIM provider I have seen most Indian backpackers use, and it has plans that cover both 7-day and 30-day stays.
The catch with eSIM: most Indian eSIM-friendly phones are dual-SIM, but the physical SIM slot becomes the eSIM slot. So you still lose one physical slot. Travellers I have spoken to who carry a Jio/Airtel SIM with international roaming often pair it with a Vietnam eSIM, then turn off roaming the moment they land.
Subodh’s Pro Tip: If your phone only has one physical SIM slot and no eSIM, buy the physical SIM at the airport. The eSIM route is only worth it if your phone supports it.
Should You Buy a SIM in India Before Flying?
Short answer: no.
The Vietnam-specific SIMs you see on Indian e-commerce sites (Amazon India, Flipkart) are usually marked up 2-3x vs airport prices, and most are eSIMs from third-party resellers rather than Viettel/Mobifone/Vinaphone direct. You also cannot top them up easily once you are in Vietnam.
What travellers sometimes buy in India is a global eSIM (Airalo Hello World, Holafly, Nomad) for use across Southeast Asia. These work fine but cost more per GB than a local Vietnamese SIM.
The pragmatic approach: buy a Vietnam tourist SIM at the airport on arrival. If you want data the moment the plane lands, add a Nomad eSIM as a backup.
What If You Stay Longer than 7 Days?
For a 10-day trip, the standard 7-day SIM will throttle on day 8. Options:
- Top up with a data pack: ₹110-₹184 (~30,000-50,000 VND or ~$1.15-$1.91) for another 3-5GB / 7 days.
- Buy the 30-day tourist SIM: ₹737-₹1,105 (~200,000-300,000 VND or ~$7.64-$11.46), includes 3-5GB and free calls.
For a 15-30 day trip, the 30-day pack is cheaper per day than buying two 7-day SIMs. If you stay longer, the 30-day tourist SIM runs ₹737-₹921 (~200,000-250,000 VND or ~$7.64-$8.94) and includes 3-5GB plus free domestic calls.
For topping up, you can hand cash to a network store, top up via the carrier’s app (requires a Vietnamese bank card or international card via the app), or use scratch cards sold at any convenience store. Read the Vietnam SIM top-up guide for the full step-by-step on each network.
Do You Need an OTP-Receiving Vietnam Number?
Most Indian travellers use Vietnamese SIMs purely for data. Google Maps, Grab, Be, WhatsApp, Telegram all work over data with your Indian number logged in.
Where it matters: if you sign up for any Vietnamese service (food delivery apps, scooter rentals, some hotel bookings), you may need a local number for SMS OTPs. In that case, the standard tourist SIM with a Vietnamese number (09x, 03x, 08x prefix) covers you. Read more in the Vietnam SIM with SMS guide.
Conversion and Money Basics for Buying a SIM
Tellers at the airport accept Vietnamese Dong (VND) only for cash payments. Bring small VND notes (10000, 20000, 50000, 100000, 200000) to avoid change issues. Most kiosks accept Visa/Mastercard but with a 2-3% foreign-card surcharge, so cash is cheaper.
If you are flying in without VND, you can withdraw from an ATM inside the airport before reaching the SIM kiosks. Most Indian debit cards work at Citibank, HSBC, and Vietcombank ATMs in arrivals. Read the INR to Vietnam currency exchange guide for the ATM-vs-cash-vs-forex-card breakdown.
For the broader “how much money to carry” question across a Vietnam trip, the Vietnam budget guide covers it.
Which Phone Works with Vietnam SIMs
Most phones sold in India in the last six years are global/quad-band GSM and work in Vietnam without any get. Two exceptions:
- Phones locked to Indian carriers (rare in 2026, but still happens with JioPhone 2 and some budget Samsung/Lava models). These will not accept foreign SIM cards until unlocked.
- CDMA-only phones (no longer common, but the original Reliance JioPhone was LTE-only, which works fine).
If your phone accepts an Indian Airtel or Vi SIM (which most phones do), it will accept a Vietnamese Viettel or Mobifone SIM.
Quick Setup Tips at the Airport
- Have your passport ready in hand as you walk out of immigration. The SIM counter staff will need to photograph it.
- State which network you want (Viettel is the safe default; if they push Mobifone, ask why).
- Ask for the SIM to be inserted and tested on the spot. Most staff do this automatically, but ask if they do not.
- Confirm your phone number on the receipt slip. Save it in your phone contacts immediately.
- Set up mobile data + APN if it does not auto-configure (rare on Android, rarer on iOS).
- Top-up with a 30-day pack if your trip is longer than 7 days to save money.
Practical Constraints: What If Your Phone Is Locked?
Phones in India that are “carrier-locked” mostly no longer exist, but if yours is, you cannot use a Vietnamese SIM until you get it. Two workarounds:
- Buy a cheap unlocked Android in Vietnam for a basic Xiaomi/Oppo, use that as your data phone for the trip. Most travellers do not bother.
- Carry a portable WiFi hotspot from India, but this still requires an unlocked phone for the hotspot itself.
In 95% of cases this is a non-issue. The other 5% have a much older or carrier-locked phone.
Common Mistakes Indian Travelers Make with Vietnam SIMs
-
Throwing away the SIM holder. The phone number and customer-service number are printed on it. If you lose it, you cannot easily recover your number at the airport counter when you fly out.
-
Not testing data before leaving the airport counter. Spend 60 seconds opening Google Maps and WhatsApp before walking out. The staff will fix any APN or registration issue right there.
-
Paying by card and getting hit with a 3% foreign-card fee. Cash in VND is cheaper if you have it. If you do not, card is fine for a ₹479 (~130,000 VND or ~$4.97) transaction.
-
Buying a 7-day SIM for a 15-day trip without budgeting the top-up. Plan the top-up so your data does not throttle in the middle of Ha Giang loop with no WiFi.
-
Skipping eSIM because “physical is simpler.” If your phone supports eSIM and you want a backup or faster airport exit, eSIM is worth the extra 100-200 rupees.
Do I Need International Roaming on My Indian SIM as a Backup?
For most of your trip, no. Your Vietnam SIM handles all data needs. But for two cases it helps:
- Receiving OTPs from Indian banks or UPI apps that send SMS OTPs to your Indian number (rare on UPI since UPI is app-based, but some banking OTPs still come via SMS).
- Lost phone scenario: if your phone dies or is stolen, having an Indian SIM active with international roaming means you can use any other phone to receive critical OTPs.
Jio and Airtel both offer ₹600-700/day international roaming packs. One day of roaming during your trip is enough as a fallback.
FAQ
How much does a Vietnam SIM card cost for Indian travellers?
The standard 7-day tourist SIM from Viettel, Mobifone, or Vinaphone costs 130000 VND at airport kiosks. At current rates (1 INR = 268 VND), that is around ₹450.
Is it cheaper to buy a Vietnam SIM in India or on arrival?
On arrival at Hanoi (Noi Bai) or HCMC (Tan Son Nhat) is cheaper. SIMs marked as “international” on Amazon India or Flipkart are usually third-party eSIMs marked up 2-3x or older-stock physical SIMs with limited data. The airport kiosks sell fresh stock at standard tourist pricing.
Which network has the best coverage in Vietnam?
Viettel. It covers rural areas (Sapa, Ha Giang, Phong Nha, Mekong Delta) more reliably than Mobifone or Vinaphone. For urban-only trips, Mobifone works fine.
Can I use my Indian phone in Vietnam?
Most phones sold in India since 2018 work in Vietnam. Phones locked to a specific Indian carrier (rare in 2026) need to be unlocked first.
Do I need a Vietnam SIM or is eSIM enough?
A Vietnam SIM is the most affordable option for data-heavy trips (around ₹450 (~$4.67) for 6GB / 7 days). ESIM from Airalo or Nomad is a good alternative if your phone supports eSIM, especially if you want data ready at landing. Both work, and many travellers carry both.
How do I top up my Vietnam SIM?
You can top up by paying cash at any Viettel/Mobifone/Vinaphone store, buying a scratch card at convenience stores (7-Eleven, Circle K, Winmart), or via the carrier’s app. The scratch card method is the most common with backpackers. The full step-by-step is in the Vietnam SIM top-up guide.
What happens if I lose my Vietnam SIM?
Keep the SIM holder with your phone number. If you lose the SIM, visit any Viettel/Mobifone/Vinaphone store with your passport, and they will block the old line and issue a replacement with the same number. The replacement cost is around ₹184 (~50,000 VND or ~$1.91).
Subodh’s Take
Buy a Viettel SIM at the airport counter as you exit immigration. Pay cash in VND if you have it. If your phone supports eSIM and you want data the second you land, layer a Nomad eSIM on top. Do not overthink this; the SIM is the cheapest gear decision on the trip.
