Quick Answers
| What | Answer | Price (INR) |
|---|---|---|
| Cheapest tourist SIM (Viettel/Mobifone, 14 days) | Tourist data SIM with ~6 GB, available at airport booths and phone shops nationwide | ₹477 (~130,000 VND or ~$4.96) |
| Best network for nationwide coverage | Viettel (largest tower network, strongest rural signal in Sapa, Ha Giang, Mekong Delta) | ₹477 (~130,000 VND or ~$4.96) |
| Do I need to register my SIM? | Yes. Passport scan + Vietnamese SIM registration required by law; the booth clerk does it for you in 5 minutes | Free at point of sale |
| Airport booth markup vs. City phone shop | Airports add a ₹110-₹184 (~30,000-50,000 VND or ~$1.14-$1.91) convenience premium; city shops are cheaper but you’ll pay a Grab to get there | ₹477 (~130,000 VND or ~$4.96) airport vs. ₹477 (~130,000 VND or ~$4.96) city |
| eSIM alternative without swapping physical SIM | Airalo, Nomad, and Holafly offer Vietnam eSIMs starting around 1 GB / 7 days; activation is QR-code based | ₹477 (~130,000 VND or ~$4.96) |
Subodh’s Pro Tip: The 14-day tourist SIM is the sweet spot for a 2-week Vietnam loop. If you’re doing a longer stay (3+ weeks through Hanoi and Ho Chi Minh City), buy the 30-day plan instead. The 14-day plan does not roll over, and recharging it inside the 14 days is awkward; the 30-day plan costs only ₹184 (~50,000 VND or ~$1.91) more.
Why You Need a Local SIM in Vietnam
Vietnam’s public Wi-Fi has improved since 2020, but it’s still patchy outside four-star hotels and the big cafes. Grab (the ride-hailing app you’ll live by), Google Maps in English, Zalo/WhatsApp to coordinate with hotels, and the occasional UPI app for INR-VND conversion all want mobile data. Travellers report that relying on hotel Wi-Fi means missing Grab drivers, getting lost in the Hoi An Old Quarter alleys, and standing helplessly outside closed convenience stores at midnight when their hotel’s Wi-Fi cut out. A local SIM solves all of this for the cost of a plate of phở.
Indian travelers specifically benefit from a Vietnamese SIM because of OTP delivery: Indian bank SMS OTPs do not arrive reliably on roaming, so any UPI transaction you want to make while abroad needs a workaround. Vietnamese tourist SIMs do receive Indian OTPs via international SMS, which means your Indian number stays reachable for the 14 to 30 days you’re on the SIM.
The Three Carriers: Viettel vs. Mobifone vs. Vinaphone
Vietnam has three major mobile carriers, plus a handful of smaller players (Vietnamobile, Gmobile) that rarely show up at tourist booths. Here’s how the big three compare for a 14-day tourist plan:
Viettel is the military-linked carrier with the largest tower footprint. Signal holds up in rural areas where the other two struggle: Sapa terraces, Ha Giang loop, Phong Nha caves, Mekong Delta homestays. The tourist SIM is sold as “Viettel Tourist” at airport booths and any phone shop with a Viettel logo (every district has at least two). Expect ~6 GB of high-speed data on the 14-day plan, then throttled but still functional speeds after. Viettel also has the best 4G/LTE coverage on the Da Nang to Hue coastal road, which matters if you’re doing the Hai Van Pass on a motorbike.
Mobifone runs a close second on coverage and is the carrier most Vietnamese under-30 prefer for urban data speeds. Their tourist SIM, sold as “Mobifone Tourist,” matches Viettel’s price and data allowance within a small margin, but Mobifone’s customer service in English is slightly better at airport booths. Mobifone is also the carrier with the widest eSIM support, so if you want a physical SIM now and an eSIM later, Mobifone is a safe default.
Vinaphone is technically state-owned, focuses on the Hanoi and Ho Chi Minh City metro markets, and offers a tourist plan that is roughly identical in price to the other two. Travellers report Vinaphone has the weakest signal in mountainous regions, but the fastest urban 4G in Hanoi Old Quarter. For most Indian backpackers doing a Hanoi-Da Nang-HCMC loop on main highways, Vinaphone works fine.
Subodh’s Pro Tip: Don’t overthink the carrier choice. All three are within 20% of each other on price and data. Pick Viettel if you’re going rural (Sapa, Phong Nha, Mekong Delta), pick Mobifone for a balanced urban-and-coastal trip, pick Vinaphone if you’re sticking to Hanoi and HCMC. The ₹110 (~30,000 VND or ~$1.14) you save by choosing the cheapest carrier is not worth a day of dropped signal in the mountains.
Airport Booth Prices (Da Nang, Hanoi, HCMC)
Every international airport in Vietnam has a row of SIM booths in the arrivals hall before you exit customs. They’re open from first flight to last flight, English-speaking, and the clerks are used to Indian passports. Prices at these booths are fixed across the three carriers: ₹477 (~130,000 VND or ~$4.96) for a 14-day tourist SIM, which works out to ₹450 at current rates (1 INR ≈ 270 VND, so 130,000 VND ≈ ₹450).
| Airport | Carrier Booths | 14-Day Tourist SIM Price | Markup vs. City Shop |
|---|---|---|---|
| Tan Son Nhat (Ho Chi Minh City) | Viettel, Mobifone, Vinaphone (3 booths, post-customs) | ₹477 (~130,000 VND or ~$4.96) | +₹110-₹184 (~30,000-50,000 VND or ~$1.14-$1.91) |
| Noi Bai (Hanoi) | Viettel, Mobifone, Vinaphone (Terminal 2 arrivals) | ₹477 (~130,000 VND or ~$4.96) | +₹110-₹184 (~30,000-50,000 VND or ~$1.14-$1.91) |
| Da Nang International | Viettel, Mobifone (single shared booth area) | ₹477 (~130,000 VND or ~$4.96) | +₹110-₹184 (~30,000-50,000 VND or ~$1.14-$1.91) |
| Cam Ranh (Nha Trang) | Viettel, Mobifone | ₹477 (~130,000 VND or ~$4.96) | +₹110-₹184 (~30,000-50,000 VND or ~$1.14-$1.91) |
| Phu Quoc International | Viettel, Mobifone | ₹477 (~130,000 VND or ~$4.96) | +₹110-₹184 (~30,000-50,000 VND or ~$1.14-$1.91) |
The airport convenience premium is real but small: ₹110-₹184 (~30,000-50,000 VND or ~$1.14-$1.91). That’s roughly the cost of a Grab ride to a city phone shop, so unless your hotel is 2 km from the airport, buying at the booth saves both time and money on day one. Travellers report that the Da Nang booth in particular is efficient, the clerk registers your card in under 5 minutes and gives you the activation receipt stapled to your passport copy.
What You Need to Buy a SIM
Vietnamese law requires every prepaid SIM to be registered to a passport before activation. This is enforced at the point of sale, not later, so you can’t buy a SIM and use it anonymously. Here’s what to have ready:
-
Passport (physical book, not a photocopy). The clerk takes it for 2 to 3 minutes to scan and photograph the photo page plus the visa page.
-
Vietnamese visa or e-visa confirmation (printed or on your phone). Your e-visa PDF from the official portal is fine. Indian travelers do not get visa-on-arrival anymore; you must have the e-visa pre-approved before flying. Apply at least 3 working days before departure at the official portal: https://evisa.xuatnhapcanh.gov.vn. The fee is ₹2,408 (~25 USD) for a 90-day, multiple-entry e-visa, which is roughly ₹2,400 at current rates (1 USD = ₹96.5289). See the Vietnam visa in 1 day guide for emergency processing.
-
Passport photo (4x6 cm, white background, taken within 6 months). Most airport booths do not require a separate physical photo because they use the digital scan, but if you’re buying from a backstreet phone shop in a district outside HCMC or Hanoi, bring one.
-
Vietnamese Dong (VND) in cash for the SIM purchase. Airport booths accept cards, but city shops often don’t. Withdraw VND from the airport ATM on arrival (Vietcombank, BIDV, and Techcombank ATMs in arrivals halls do not surcharge Indian debit cards beyond the standard ~₹81 (~22,000 VND or ~$0.84) international transaction fee your bank adds).
-
Your unlocked phone. Indian iPhones and most Android flagships sold since 2018 are unlocked by default. If you’re on Jio or Airtel postpaid with carrier-locked phones, get them unlocked before flying. A locked phone will accept a Vietnamese SIM physically but will throw “SIM not supported” errors when trying to register on the network.
Safety Alert: There are scam operators at certain airport booths (mostly at smaller terminals like Phu Quoc and Cam Ranh) who push overpriced packages, such as “₹1,927 (~20 USD) recharge bundles” or “special tourist deals at ₹734 (~200,000 VND or ~$7.62).” The legitimate tourist SIM is ₹477 (~130,000 VND or ~$4.96) at any official booth. If a clerk is pushing a plan priced above ₹551 (~150,000 VND or ~$5.72), walk to the next booth. Official booths are branded with the carrier logo and a price list on the wall.
Step-by-Step: Buying at an Airport Booth
Here’s the exact sequence at any Vietnamese airport, based on what travellers report from Tan Son Nhat, Noi Bai, and Da Nang:
Step 1: Land, clear immigration, collect checked baggage. SIM booths are in the public arrivals hall, after customs, before the taxi/Grab pickup area. Do not stop at the “SIM card” guys waving at you in the secure area before immigration; those are unofficial resellers with inflated prices.
Step 2: Approach the carrier booth you want. Each booth has a staff member holding a tablet and the SIM cards. Tell them “tourist SIM, 14 days” or “tourist SIM, 30 days” if you want the longer plan.
Step 3: Hand over your passport. The clerk will photograph the photo page and visa page on their tablet, ask for your Vietnamese phone number (you don’t have one yet, this is normal), and ask for your home country address (your hotel’s address in Vietnam is fine).
Step 4: Pay. ₹477 (~130,000 VND or ~$4.96) for the 14-day plan, ₹661 (~180,000 VND or ~$6.86) for the 30-day plan. Cash or card both work. You’ll get a receipt stapled to your passport copy, plus the SIM card itself in a small carrier-branded envelope.
Step 5: Insert the SIM. The clerk will usually offer to insert it for you and confirm the signal bars appear on your phone. This is the moment the SIM registers on the network, which can take 2 to 10 minutes. Don’t panic if you have no signal for the first 5 minutes; activation is asynchronous.
Step 6: Test data. Open Google Maps and search for “Ho Chi Minh City” or “Da Nang.” If the map loads over 4G, you’re set. If you only see Wi-Fi signal, toggle airplane mode for 30 seconds and retry.
Total time from booth to working data: 10 to 15 minutes. Total cost: ₹477 (~130,000 VND or ~$4.96) for the 14-day plan.
Buying in the City (Phone Shops vs. Convenience Stores)
If you skipped the airport and need a SIM mid-trip, every Vietnamese city has phone shops in commercial districts. Here’s how the channels differ:
Carrier-branded shops: Look for the Viettel, Mobifone, or Vinaphone logo on a green/red/yellow storefront. Staff speak some English, prices match the airport (₹477 (~130,000 VND or ~$4.96) for 14 days), and they handle registration the same way. In Hanoi, the Viettel shop on Phan Dinh Phung Street and the Mobifone shop on Tran Hung Dao are well-staffed for English-speaking tourists.
Independent phone shops: Smaller, often cheaper (₹294-₹367 (~80,000-100,000 VND or ~$3.05-$3.81) for the 14-day plan) because they buy in bulk. That’s ₹110-₹184 (~30,000-50,000 VND or ~$1.14-$1.91) less than the airport booths. The catch: registration still requires your passport, and some shops will not register for you unless you spend extra on a recharge card. Avoid shops that won’t show you the packaging before purchase.
7-Eleven and Circle K: Convenience stores sell tourist SIMs in Hanoi and HCMC, but the selection is limited (usually just Mobifone or Vinaphone, never all three) and the staff cannot help with registration. You’d need to register online later via the carrier app, which adds an hour of friction.
For most Indian travelers, the airport booth is the right call on day one because it works on a tired post-flight brain, and the convenience premium is roughly the cost of one Grab ride.
eSIM Alternatives (Airalo, Nomad, Holafly)
If you’d rather keep your Indian SIM active for OTP delivery, an eSIM is the cleaner option. ESIMs are digital SIMs that download to your phone without a physical card. You activate by scanning a QR code, and your phone runs two networks at once: the Indian SIM for calls/OTPs, the Vietnamese eSIM for data.
Three providers are reliable for Vietnam:
Airalo is the most popular with Indian travelers. The “Explorer” Vietnam plan runs about 1 GB for 7 days at ₹434 (~4.50 USD), or 3 GB for 15 days at ₹867 (~9 USD), or 5 GB for 30 days at ₹1,445 (~15 USD). Activation is QR-code based, no passport registration required because the eSIM is tied to your device IMEI, not a SIM card. The catch: Airalo data is throttled to 3G speeds in Vietnam, not full 4G, so Google Maps and WhatsApp work but video calls buffer.
Nomad runs a Vietnam regional plan with 1 GB for 7 days at ₹385 (~4 USD), 3 GB for 15 days at ₹867 (~9 USD), or 10 GB for 30 days at ₹2,408 (~25 USD). Speeds are 4G/LTE on Viettel’s network because Nomad leases capacity from Viettel directly. For Indian travelers doing a full month, Nomad is cheaper than Airalo per gigabyte. Get Nomad eSIM.
Holafly offers unlimited data plans, which sound appealing until you read the fine print: Holafly’s “unlimited” plans throttle to 512 kbps after 3 GB/day, which makes video unusable. The price is also higher than Airalo or Nomad per day. For most Indian travelers, Holafly is overkill.
Subodh’s Pro Tip: If you’re going for an eSIM, your phone must be eSIM-compatible. IPhone XS and newer, Google Pixel 3 and newer, Samsung Galaxy S20 and newer, and most 2021+ mid-range Android phones work. Older phones, including the iPhone X and earlier, cannot use eSIMs. Bring a physical SIM as backup if your phone is borderline.
Recharging and Top-Up
The 14-day plan gives you ~6 GB and 14 days of validity. After that, the SIM goes dead and you cannot receive calls or SMS. Top-up is straightforward:
- At phone shops: Buy a recharge card (thẻ cào) for 50,000 / 100,000 / 200,000 / ₹1,836 (~500,000 VND or ~$19.06) denominations. Scratch off the back, dial 100cardnumber#, and the balance is added. The clerk at any carrier shop will do this for you for free if you ask.
- Carrier apps: Viettel (My Viettel), Mobifone (My Mobi), and Vinaphone (My VNPT) all have English-language apps. Top-up via international credit card inside the app. Indian Visa and Mastercard cards work; RuPay does not.
- Banking apps: GrabPay (linked to your Indian card) can top up your SIM via the carrier’s app integration. Travellers report this is the smoothest option for Indian cardholders.
- At convenience stores: 7-Eleven and Circle K clerks will top up your SIM for cash if you give them your phone number and the amount. They dial the recharge code for you. Costs the same as buying a recharge card.

Data Coverage: City vs. Mountain vs. Coast
Coverage varies enough between Viettel, Mobifone, and Vinaphone that picking the right one for your route matters:
Cities (Hanoi, HCMC, Da Nang): All three carriers run full 4G/LTE in central districts. Vinaphone is marginally fastest in HCMC’s District 1, Mobifone marginally fastest in Hanoi’s Old Quarter. Viettel is fine in both.
Coastal road (Da Nang to Hue, Hai Van Pass): Viettel has the most consistent signal along Highway 1A. Mobifone drops signal in the Hai Van tunnel section. Vinaphone drops signal between Lang Co and Hue on the coastal bypass.
Mountains (Sapa, Ha Giang Loop, Phong Nha, Ninh Binh): Viettel wins decisively. Sapa town has all three carriers, but the rice terrace trails and Ha Giang mountain passes run on Viettel or nothing. Travellers on Mobifone report dead zones on the Ma Pi Leng Pass.
Islands (Phu Quoc, Nha Trang coast): All three work, but coverage drops sharply on boat trips to offshore islands. Don’t expect signal on a Phu Quoc snorkeling tour.
For a full Vietnam loop hitting coast and mountains, Viettel is the safest pick.
Currency, Payment, and Budget Reality
At current rates (1 INR ≈ 270 VND), here’s what the SIM math looks like for a 14-day Vietnam trip:
| Item | Cost (VND) | Cost (INR) |
|---|---|---|
| 14-day tourist SIM (airport booth) | ₹477 (~130,000 VND or ~$4.96) | ₹450 (~$4.67) |
| 30-day tourist SIM (airport booth) | ₹661 (~180,000 VND or ~$6.86) | ₹620 (~$6.44) |
| 14-day SIM (city phone shop) | ₹294-₹367 (~80,000-100,000 VND or ~$3.05-$3.81) | ₹294-₹367 (~$3.05-$3.81) |
| Airalo eSIM (3 GB / 15 days) | ₹867 (~9 USD) | ₹870 (~$9.03) |
| Nomad eSIM (3 GB / 15 days) | ₹867 (~9 USD) | ₹870 (~$9.03) |
| Top-up recharge (₹184 (~50,000 VND or ~$1.91) card) | ₹184 (~50,000 VND or ~$1.91) | ₹175 (~$1.82) |
| One-time airport ATM withdrawal fee | ₹81 (~22,000 VND or ~$0.84) | ₹75 (~$0.78) |
A typical 2-week Vietnam trip sees a traveler spend ₹477-₹845 (~130,000-230,000 VND or ~$4.96-$8.77) on SIM-related costs (initial SIM + one or two top-ups). The Airalo eSIM costs roughly double that for equivalent data, so a physical SIM from an airport booth remains the cheapest path for budget travelers.

Common Mistakes Indians Make Buying a Vietnam SIM
Mistake 1: Buying from unofficial airport resellers. The guys waving SIM cards at you inside the secure arrivals area (before immigration) are unofficial. Their “tourist SIM” is a regular prepaid SIM sold at 2x to 3x markup, with no registration help. Always walk past immigration, collect your bag, then buy at the official carrier booths in the public arrivals hall.
Mistake 2: Forgetting to get the phone. Indian carrier-locked phones (especially older Airtel postpaid and Jio locked devices) will physically accept the SIM but show “SIM not supported.” If your phone is locked, you’ll need to call your Indian carrier and request an get code before flying. This takes 24 to 48 hours.
Mistake 3: Not carrying the passport to the booth. Vietnamese registration is enforced at point of sale. If you leave your passport in checked luggage, you can’t buy a SIM until you reach the hotel. Keep your passport in your carry-on.
Mistake 4: Buying the wrong duration plan. The 14-day plan is for 14 calendar days, not 14 days of use. If you arrive in Vietnam at 10 PM on day 1, your 14 days expire at 10 PM on day 14, even if you only used 2 GB. Travellers report this catches people who arrive late on a Friday and lose their SIM before the next weekend.
Mistake 5: Skipping the e-visa and trying to sort a SIM on a tourist-visa-free entry. Indians do not get visa-free entry to Vietnam. You must have the e-visa pre-approved. Without an e-visa page in your passport, SIM registration will fail, the clerk will not sell to you, and you’ll spend your first night offline. Apply at the official portal before flying.
Safety Alert: SIM registration data is held by the carrier and shared with Vietnamese authorities. This is normal for any country with mandatory SIM registration (India has the same rule under DoT norms). Don’t worry about data privacy beyond standard practice. Don’t buy from “no registration” resellers: their SIMs are prepaid with leftover KYC from someone else, and they get disabled within 30 days when the registration is rejected.
FAQ
Q: Can I buy a Vietnamese SIM with an Indian debit card, or do I need cash?
A: Airport booths accept both cards and cash, so a Visa or Mastercard debit works. City phone shops often don’t take cards, so cash in VND is safer. Withdraw VND from the airport ATM on arrival; the international transaction fee is ₹81 (~22,000 VND or ~$0.84) per withdrawal.
Q: How long does the SIM take to activate after I buy it?
A: 2 to 10 minutes. Insert the SIM, wait for signal bars to appear, then test data. If no signal after 15 minutes, restart the phone and wait another 5 minutes. If still nothing, return to the booth for a replacement.
Q: Will my Indian bank OTPs arrive on a Vietnamese SIM?
A: Yes, Indian OTPs (for UPI, IRCTC, banking apps) deliver via international SMS to a Vietnamese number, though sometimes with a 2 to 5 minute delay. If you need reliable instant OTP, keep your Indian SIM active in a dual-SIM phone and use the Vietnamese SIM for data only.
Q: Can I keep my Indian SIM active while using a Vietnamese SIM?
A: Yes, if your phone is dual-SIM (all modern phones are). Indian SIM in slot 1 for calls/SMS/OTPs, Vietnamese SIM in slot 2 for data. Set data routing to the Vietnamese SIM in your phone settings. Or use an eSIM to keep your physical SIM slot free for the Vietnamese card while the Indian SIM stays in slot 1.
Q: Is there a way to buy a SIM before I land in Vietnam?
A: Not officially for a Vietnamese number. You can buy an Airalo or Nomad eSIM online before departure and activate it on landing via QR code. Klook also sells Vietnam SIM cards for airport pickup, but the price is higher than buying at the airport booth.
Q: What happens to my Vietnamese SIM when I leave Vietnam?
A: The SIM dies at the end of its validity period (14 or 30 days). You can keep the physical card as a souvenir, but it has no use outside Vietnam. Any remaining balance is forfeited when the SIM expires, so spend down the data before you fly out.
Q: Will my phone work on Vietnamese networks?
A: Yes, if it’s unlocked and supports the bands used in Vietnam. Most Indian-market phones (iPhone, Samsung, OnePlus, Xiaomi) support Vietnam’s 4G bands (B1, B3, B7, B8). If you have a carrier-locked or India-only variant, check the spec sheet for 4G LTE band compatibility before flying.
Subodh’s Take
Buy at the airport booth. The ₹110 (~30,000 VND or ~$1.14) premium is one coffee, and it skips a 10 PM Grab ride to a phone shop when you’re jetlagged. Pick Viettel unless you have a specific reason to pick otherwise (going to Phu Quoc with a Holafly eSIM, sticking to HCMC where Vinaphone is slightly faster, etc.). For a 14-day trip, the 14-day plan at ₹477 (~130,000 VND or ~$4.96) is enough. For longer, the 30-day plan. If you’re keeping your Indian SIM for OTPs, get an Airalo or Nomad eSIM instead and skip the physical SIM dance. Either way, do this before you leave the airport terminal, not after you reach the hotel.
