The Three Main Carriers: Who They Are
Vietnam’s mobile market is a near-tie between three state-backed carriers. As a tourist you only need to know the differences in their tourist packs.
- Viettel is the largest, with the best rural and mountain coverage. International call rates to India are also lowest on Viettel.
- Mobifone has solid urban 4G in major cities. Slightly cheaper tourist SIMs during promotional months.
- Vinaphone is the smallest of the three and strongest in northern Vietnam. Tourist packs are almost always priced identically to Mobifone, with a few extra freebies (sometimes a free Grab voucher or a week of free Spotify).
In Hanoi and HCMC, you’ll have working 4G on all three. In the Mekong Delta, Phu Quoc, or the central highlands, coverage is uneven. The base 14-day tourist SIM listed in the canonical price registry is ₹479 (~130,000 VND or ~$4.97) for around 6GB of data, available at all three carriers. That’s the single most common price point an Indian backpacker will see on the shelf in 2026.
Tourist SIM Price Comparison: Daily, Weekly, Monthly
The “tourist SIM” is a fixed plan, not à la carte. You pick a pack, pay once, get data and minutes bundled. Here is what each carrier sells in 2026, in the plan windows Indian backpackers use.
| Carrier | Plan | Data | Validity | Price (VND) | Price (INR) |
|---|---|---|---|---|---|
| Viettel | Tourist 7-day | 3GB/day, 30GB total | 7 days | 100,000 | ₹370 (~$3.84) |
| Viettel | Tourist 14-day | 4GB/day, 56GB total | 14 days | 180,000 | ₹665 (~$6.90) |
| Viettel | Tourist 30-day | 3GB/day, 90GB total | 30 days | 250,000 | ₹925 (~$9.60) |
| Mobifone | Tourist 7-day | 3GB/day, 21GB total | 7 days | 90,000 | ₹333 (~$3.45) |
| Mobifone | Tourist 14-day | 4GB/day, 56GB total | 14 days | 170,000 | ₹630 (~$6.54) |
| Mobifone | Tourist 30-day | 3GB/day, 90GB total | 30 days | 230,000 | ₹850 (~$8.82) |
| Vinaphone | Tourist 7-day | 3GB/day, 21GB total | 7 days | 90,000 | ₹333 (~$3.45) |
| Vinaphone | Tourist 14-day | 4GB/day, 56GB total | 14 days | 170,000 | ₹630 (~$6.54) |
| Vinaphone | Tourist 30-day | 3GB/day, 90GB total | 30 days | 230,000 | ₹850 (~$8.82) |
Subodh’s Pro Tip: The “daily X GB” framing on the carrier websites is genuinely per-day, not a single chunk. If you use all 4GB on day one, your speed drops to a near-unusable 256kbps until midnight, then resets. Travellers report this trick catches first-time buyers off guard.
For a standard 2-week Hanoi to Hoi An to HCMC route, the 14-day pack at any carrier covers it. For a longer trip that includes the south (Phu Quoc, Mekong) or north (Sapa, Ha Giang), get the 30-day pack and don’t risk running out on day 12 in a sleeper bus.
Airport Kiosk vs. City Store: The Real Markup
The airport desk price is consistently higher. From traveller reports, the markup ranges from ₹110-₹184 (~30,000-50,000 VND or ~$1.15-$1.91) on the same pack.
| Plan | Airport price (VND) | City store price (VND) | Markup (VND) | Markup (INR) |
|---|---|---|---|---|
| 7-day tourist | 130,000 | 90,000 | 40,000 | ₹148 (~$1.54) |
| 14-day tourist | 200,000 | 170,000 | 30,000 | ₹111 (~$1.15) |
| 30-day tourist | 280,000 | 230,000 | 50,000 | ₹185 (~$1.92) |
The reason is straightforward: the airport desk has a captive audience, no price comparison, and high rent. The desk staff are on commission. The only advantage of buying at the airport is that your SIM is working before you leave arrivals, which matters if your hotel isn’t pre-booked and you need Grab right away.
Subodh’s Pro Tip: If you have a Vietnam e-Visa, your passport, and a working phone, wait until you reach your hotel. Walk into any Viettel/Mobifone/Vinaphone branded store in central Hanoi or District 1 HCMC. Show your passport, pick the 14-day pack, pay in cash, and walk out with 4GB/day for ₹626 (~170,000 VND or ~$6.49). Total time: 10 minutes. Saving: ₹110 (~30,000 VND or ~$1.15) on the spot.
If you do need the SIM immediately, the airport is fine, just pick the cheapest counter (the three carriers are usually clustered together, compare and haggle politely).
How to Activate and Get Set Up
All three carriers follow the same process:
- Passport check (mandatory, photo taken or scanned).
- Pick the tourist pack and pay in VND cash. Most city stores also accept card, but cash is smoother.
- SIM swap in the store, they do it for you.
- Top up at the cashier if you want extra data or minutes beyond the pack.
- Register your phone with the carrier if you bought the SIM yourself at a convenience store. For tourist packs bought at official carrier stores, this is automatic.
Your phone will work the moment the staff hand it back. 4G usually kicks in within 30 seconds. APN settings are sent via SMS automatically, no manual config needed on modern iPhones or Androids.
International Calls Back to India
This is the part most guides skip, and it’s the difference between staying in touch with family or not. Viettel wins on IDD (international direct dial) rates to India, by a clear margin.
| Carrier | India landline (VND/min) | India mobile (VND/min) | India mobile (INR/min) |
|---|---|---|---|
| Viettel | 1,800 | 2,500 | ₹9 (~$0.09) |
| Mobifone | 2,500 | 3,200 | ₹12 (~$0.12) |
| Vinaphone | 2,500 | 3,200 | ₹12 (~$0.12) |
Subodh’s Pro Tip: The catch is that the IDD rates only apply when you use the carrier’s USSD code or call from the dialler with the international prefix. If you use WhatsApp, Telegram, or FaceTime Audio on your 4G, calls to India are free. Most Indian backpackers I know have used exactly zero paid minutes back home, they just use WhatsApp on the 4G they already paid for.
If you do need a real call (some Indian banks require OTP voice calls, and Vietnam’s SMS delivery for foreign numbers is patchy), see our Vietnam SIM with SMS guide for the workaround.
eSIM: The Airport-Skip Alternative
If your phone supports eSIM (iPhone XR and newer, most 2020+ Androids), you can skip the airport counter entirely. Order a regional SEA eSIM before you fly, land, scan the QR, and you’re online in the arrivals hall.
The single best option for India-to-Vietnam travellers is Nomad. The data-only regional packs cover Vietnam, Thailand, Laos, and Cambodia on one eSIM, which is useful if you’re combining Vietnam with a Bangkok leg. Get Nomad eSIM before you board your flight from India, and you’ll have data the moment the plane’s wheels touch the runway.
The downsides: eSIMs are data-only, you get no Vietnamese phone number, and IDD voice calls won’t work the same way. For most Indian backpackers running WhatsApp, this is fine.
Topping Up Your SIM Mid-Trip
Run out of data on day 8 of a 14-day pack? All three carriers sell daily and weekly add-ons. You can top up at any branded store, at Circle K and 7-Eleven, or via the carrier’s app.

Common Mistakes Indians Make With Vietnam SIMs
- Buying the 7-day pack for a 2-week trip. The per-GB cost of the 14-day pack is meaningfully lower. If you know your trip length, skip the 7-day.
- Skipping the passport. Vietnamese law requires SIM registration. Convenience stores and street sellers will not activate a SIM without your passport in hand.
- Trusting “unlimited” claims. The “high-speed” data is capped daily, after which speeds throttle hard. Use the daily allowance for maps and WhatsApp, and rely on hostel WiFi for streaming.
- Skipping USSD balance checks. Dial *100# (Viettel), *101# (Mobifone), or *100# (Vinaphone) to see remaining data. Don’t guess.
- Losing the SIM tray ejector pin. Most modern phones need a pin to swap SIMs. If your hostel doesn’t have one, the front desk usually does.
Data Usage on a 2-Week Vietnam Trip
A rough realistic budget for an Indian backpacker doing Hanoi → Ha Long Bay → Ninh Binh → Hoi An → HCMC:
- Google Maps with navigation: 200-300MB/day
- WhatsApp voice and video calls: 200-400MB/day
- Instagram and Reels scrolling: 200-500MB/day
- Grab, food delivery, translation apps: 50-100MB/day
- Hotel/hostel WiFi offloads the heavy stuff (Netflix, YouTube, video calls)
Total: 1-2GB/day. The 14-day pack at 4GB/day is more than enough.
For a full month including Phu Quoc and Mui Ne, expect 1.5-2.5GB/day, and the 30-day pack is the only sensible choice.
eSIM vs Physical SIM: Which One for India Departures
| Factor | eSIM (Nomad) | Physical SIM (Viettel/Mobifone/Vinaphone) |
|---|---|---|
| Buy before flying from India | Yes | No |
| Activation time | 2 minutes after landing | 10 minutes at a store |
| Local phone number | No | Yes |
| IDD voice calls to India | Limited | Yes, full rate |
| Price for 2 weeks, ~30GB | ₹1,200-₹1,500 (~$12.45-$15.56) | ₹630-₹665 (~$6.54-$6.90) |
| Best for | Short trips, data-only | Trips needing SMS/OTP/voice |
FAQ
Can I use my Indian SIM in Vietnam with international roaming? Yes, but it’s expensive. Airtel and Jio charge around ₹650-₹1,200 (~$6.74-$12.45) per day for international roaming, far above the ₹626 (~170,000 VND or ~$6.49) you’d pay for a 14-day Vietnamese tourist SIM with 56GB. Roaming is only worth it for emergencies.
Does my Indian eSIM work in Vietnam? Airtel and Jio eSIMs do roam, but again at international data rates. A local eSIM is 80-90% cheaper.
Can I get a SIM at Da Nang or Hoi An, or only at the airports? Yes, all three carriers have branded stores in central Da Nang, Hoi An, and most major Vietnamese cities. Walk-in, passport, 10 minutes.
Will my Vietnam SIM work across the border in Cambodia, Laos, or Thailand? No. Vietnamese tourist SIMs are domestic-only. If you’re doing a multi-country loop, either get a regional eSIM (Nomad covers all four) or buy a new SIM at the border.
What if my phone is locked to Jio or Airtel? You’ll need to get it before leaving India. Both carriers allow unlocking after 12 months of usage. Airtel processes gets you faster (usually 24-48 hours via the Airtel Thanks app).
How much cash should I carry in VND for the SIM? At the city store, ₹847 (~230,000 VND or ~$8.79) covers the most expensive 30-day pack. Carry that much in small notes and you’ll be sorted.
Subodh’s Take
If your trip is 2 weeks or less and you stay on the Hanoi to HCMC corridor, buy the Mobifone 14-day pack at a city store in Hanoi. It’s ₹110 (~30,000 VND or ~$1.15) cheaper than Viettel and the coverage on the main tourist route is identical. If you’re heading to Sapa, Ha Giang, or any mountain stretch, pay the ₹37 (~10,000 VND or ~$0.38) premium for Viettel, the rural coverage difference is real. And if you have a modern phone with eSIM, the Nomad regional pack genuinely beats both on convenience, just remember you’ll have no Vietnamese phone number for SMS OTPs.
