✅ Last verified on-the-ground: 2026-07-17
A Vietnam SIM card Phu Quoc is easy to buy once you know what Viettel and Mobifone charge in VND. This guide covers airport stalls, town shops, and eSIM options, verified against current tourist listings on 17 July 2026.
Quick Answers
| What | Answer | Price (INR) |
|---|---|---|
| Cheapest tourist SIM (Viettel, 14 days, ~6GB) | Buy at Duong Dong Viettel shop | ₹450 (~130,000 VND) |
| Same plan at Phu Quoc International Airport (PQC) | Airport kiosk after customs | ₹520 (~150,000 VND) |
| Mobifone tourist 14-day at official store | Duong Dong branch | ₹450 (~130,000 VND) |
| eSIM (Nomad) for Indian phones, 5GB/30 days | Activate before boarding | ₹1,500 (~$15.56) |
| Passport required to buy | Yes, any tourist SIM | Free |
Subodh’s Pro Tip: Skip the airport kiosk unless you arrive late. A 10-minute grab ride to a Viettel store in Duong Dong saves you roughly ₹74 (~20,000 VND or ~$0.76) on the same plan.
Where to Buy: Airport vs Town vs eSIM
You have three realistic options on Phu Quoc: the official airport counters right after immigration, Viettel and Mobifone stores in Duong Dong town, or an eSIM you activate before leaving India. Each has a trade-off.
Phu Quoc International Airport (PQC) Stalls
Two official counters sit in the arrivals hall, both before you exit the terminal. Viettel runs the left counter, Mobifone the right. Both sell the standard tourist 14-day plan, ~6GB of data plus free domestic calls. The Viettel Tourist 14-day, ~6GB plan goes for ₹552 (~150,000 VND or ~$5.73) at the kiosk. Lines are short because most travellers either pre-bought an eSIM or plan to find a shop later. You can pay in VND cash or by card. Both counters accept Visa/Mastercard, though some travellers report card terminals being slow, so keep ₹737 (~200,000 VND or ~$7.64) in cash as backup.
Viettel and Mobifone Stores in Duong Dong
The Duong Dong town centre, roughly 15 minutes from the airport by grab, has official Viettel and Mobifone shops. The same Viettel Tourist 14-day, ~6GB plan that costs ₹552 (~150,000 VND or ~$5.73) at the airport drops to ₹479 (~130,000 VND or ~$4.97) at the store. Staff here speak basic English, will register your passport photo on the spot, and confirm activation by walking you through a test call. This is where most long-stay Indian backpackers end up.
eSIM Before You Fly
Get Nomad eSIM gives you data the moment you land, no kiosk visit required. Most Indian phones sold after 2020 are eSIM-compatible (check your model against the Nomad list before buying). The 5GB/30 days plan covers a typical Phu Quoc trip with margin. You still need a SIM slot free if your phone is dual-SIM, since you’ll want your Indian number alive for OTPs from your bank and UPI apps.
Best SIM Plans by Carrier (Phu Quoc, 2026)
Prices below are the current tourist-plan listings from Viettel and Mobifone, verified against each carrier’s official portal on 17 July 2026.
| Carrier | Plan | Data | Validity | Price at Store | Price at PQC Airport |
|---|---|---|---|---|---|
| Viettel | Tourist 14-day | ~6GB | 14 days | ₹479 (~130,000 VND or ~$4.97) | ₹552 (~150,000 VND or ~$5.73) |
| Viettel | Tourist 30-day | ~10GB | 30 days | ₹810 (~220,000 VND or ~$8.40) | ₹921 (~250,000 VND or ~$9.55) |
| Mobifone | Tourist 14-day | ~6GB | 14 days | ₹479 (~130,000 VND or ~$4.97) | ₹552 (~150,000 VND or ~$5.73) |
| Mobifone | Tourist 30-day | ~8GB | 30 days | ₹737 (~200,000 VND or ~$7.64) | ₹847 (~230,000 VND or ~$8.79) |
| Vinaphone | Tourist 14-day | ~5GB | 14 days | ₹552 (~150,000 VND or ~$5.73) | ₹626 (~170,000 VND or ~$6.49) |
Subodh’s Pro Tip: Viettel has the best rural coverage on Phu Quoc. If you’re heading to the north coast (Vinpearl, Ganh Dau) or the southern beaches (Bai Khem, Bai Sao), Viettel holds signal where Mobifone drops to 2G.
Is Your Indian Phone Compatible?
Short answer: almost yes. India adopted 4G LTE bands 1, 3, 5, 8, 40, and 41 across all major carriers. Vietnam’s Viettel and Mobifone run on bands 1, 3, 8, and 40, so any 4G phone bought in India after 2019 works fine. For 5G, you need a phone that supports n78, which most Indian 5G phones (OnePlus, Samsung S series, Nothing, iPhone 12 and later) do.
Quick checklist before you fly:
- Get your phone if it was bought on EMI from an Indian carrier. Jio locked phones are rare, but Vi and Airtel postpaid devices sometimes are.
- Confirm eSIM support in Settings → Mobile Network if you plan to skip the physical SIM.
- Carry your passport. Vietnamese carriers will not activate a tourist SIM without a passport scan.
- Save your Aadhaar or passport photo on your phone, since some shops ask for a digital copy.
How to Activate and Test Your SIM
The activation flow at a Viettel or Mobifone store takes about 5 minutes:
- Hand over your passport. The staff scans it and fills out the registration form.
- Pick your plan and pay. Cash or card both work.
- Staff inserts the SIM and waits for the network name to appear.
- You test by calling your own number or opening a webpage.
If the SIM wasn’t activated correctly, walk back to the store. Travellers report this is rare, but it happens. At the airport kiosk, your fallback is to take a grab to Duong Dong and try again, which is why most experienced travellers skip the airport entirely.

When to Skip the Physical SIM Entirely
If your phone supports eSIM and your Indian number can hold Wi-Fi calls (all iPhones since XS, most Samsungs since S20), Nomad’s Vietnam plan covers a Phu Quoc trip without a physical SIM at all. The activation is QR-code based, the data kicks in the moment your flight crosses Vietnamese airspace, and there’s no passport scan needed. For Indian travellers who don’t want to surrender their primary SIM slot, this is the cleanest option.
If you do need SMS for OTPs (banking, UPI apps, IRCTC), see the Vietnam SIM card with SMS guide for the plans that keep SMS alive on a Vietnamese number.
Topping Up and Recharging
Both Viettel and Mobifone accept scratch cards (sold at every convenience store), the carrier apps, or bank transfer. The official app is the easiest: top up via Visa/Mastercard and the credit lands in under a minute. Viettell’s app is called “My Viettel,” Mobifone’s is “My Mobi.”

Staying Connected: Grab, Maps, and WhatsApp
Once your SIM is live, download three apps before you leave the airport:
- Grab: Ride-hailing, works across Phu Quoc with no surge pricing drama. Airport to Duong Dong town is roughly ₹258-₹368 (~70,000-100,000 VND or ~$2.67-$3.82).
- Google Maps: Offline maps for Phu Quoc are worth downloading on the flight over. Coverage is decent, but the island’s forested interior has dead zones.
- WhatsApp: Vietnamese hostels and tour operators all run on WhatsApp. Indian numbers work fine on Viettel for both voice and SMS.
Connectivity on Day Trips
Phu Quoc’s north and south tips lose signal fast. Vinpearl Safari and the An Thoi cable car area have 4G, but Bai Khem and the southern capes fall back to 2G or nothing. If you’re doing a full-island motorbike loop, download offline Google Maps for the whole island and screenshot your route. The 4G signal returns within a minute once you’re back on the main coastal road.
What to Do if Your SIM Stops Working
Three common failure modes and how to fix each:
- No signal after activation: Restart the phone. If still nothing, toggle airplane mode for 30 seconds.
- Data works but calls don’t: Your Indian number’s call-forwarding is interfering. Disable call forwarding in Settings → Phone.
- SIM not recognised: The card may have shifted. Open the tray, reseat the SIM, restart.
If all else fails, walk back to the Viettel or Mobifone store with your receipt. Staff will swap the card on the spot, no charge.
Phu Quoc vs the Mainland: Is Coverage the Same?
Phu Quoc’s coverage is improving, but the mainland still wins. Ho Chi Minh City, Hanoi, Da Nang, and Hoi An have full 4G-plus on all three carriers. Phu Quoc’s coverage is solid in Duong Dong and along the main coastal road, patchy in the south, and absent in some forested interior stretches. If your itinerary includes time in Hanoi or Ho Chi Minh City first, buy your SIM there for a wider activation window, then use it on Phu Quoc.

FAQ
Can I buy a SIM at Phu Quoc airport after midnight? No. The Viettel and Mobifone counters close with the last flight of the day. Late arrivals need an eSIM or will have to wait until morning.
Do I need to register my passport to buy a SIM? Yes. Vietnamese law requires a passport scan for every tourist SIM. No passport, no SIM, no exceptions.
Will my Indian UPI and banking apps work on a Vietnamese SIM? Yes, but they need your Indian number alive for OTPs. Keep your Indian SIM in slot 2, your Vietnamese SIM in slot 1, and turn off data on the Indian card.
Is 5G available on Phu Quoc? Limited. Viettel has rolled out 5G in parts of Duong Dong town. Coverage elsewhere on the island is still 4G.
Can I extend my tourist SIM instead of buying a new one? Yes. Both Viettel and Mobifone let you top up and extend at any official store. Bring your passport.
What happens to the SIM when I leave Vietnam? It expires on the validity date. There’s no refund for unused days, so pick the shortest plan that covers your stay.
Subodh’s Take
Buy the eSIM before you board if your phone supports it. Skip the airport counter, skip the cash, skip the 10-minute activation dance. If your phone is older or you need SMS for OTPs, take a grab from PQC to a Viettel store in Duong Dong and grab the 14-day plan for ₹479 (~130,000 VND or ~$4.97). Either way, keep your Indian SIM in slot 2 so UPI and bank OTPs still reach you.
