One thing most people don’t realize about Phu Quoc: it’s bigger than it looks on the map. Long Beach and the resort strip are just a sliver of the island. The National Park covers the entire north. Sao Beach is a 30-minute drive south. The An Thoi Archipelago is a boat ride away. In these remote areas, your carrier choice actually matters – a signal that works in town might disappear the moment you start your scooter. This article explains all the basics about Phu Quoc SIM cards and eSIMs to ensure you stay connected for navigation and safety, whether you sort it before or after landing.
The Quick Win:
- For Explorers (Scooters, National Park, Ganh Dau): Get Viettel. It has the only signal that survives the northern trails.
- For Resort Stayers (Long Beach, Duong Dong, Vinpearl): MobiFone or Vinaphone are faster and cheaper.
- Best Convenience: Buy a Vinaphone eSIM before you land to skip all airport queues.
I. Which Carrier Should You Get in Phu Quoc?
Choose Viettel if you’re renting a scooter or heading off the beaten track. MobiFone or Vinaphone if you’re staying resort-side.
Here is the details:
- Viettel, the biggest carrier in Vietnam, is the winner of coverage. It holds a signal where others give up – National Park trails, the northern coast near Ganh Dau, and remote beaches. If you’re renting a scooter to find an empty beach on the far side of the island, get Viettel.
- MobiFone covers all the places that most tourists actually go to: Long Beach, Duong Dong, Vinpearl, Hon Thom Cable Car, and Sao Beach. It’s usually cheaper per GB than Viettel and offers excellent 5G speeds in town. MobiFone is fine for 80% of Phu Quoc trips.
- Vinaphone is similar to MobiFone in the main zones but slightly weaker in remote zones. The biggest advantage: it is the cheapest option that offers plans with both data and a local number for tourists to Vietnam.
| Your trip | Go with | Reasons |
| Resort stay, Long Beach, Phu Quoc beaches | MobiFone or Vinaphone | Cheapest & fastest in developed zones. |
| Scooter trips, national park, remote spots | Viettel | Only network with rural coverage. |
| Island hopping, An Thoi | Viettel or MobiFone | Best signal on the water. |
| Working remotely, need reliability | Viettel | Most reliable back-up. |

II. Buying a MobiFone physical SIM card on Phu Quoc island
1. At the airport (Fast but costly)
After walking out of the baggage claim, you will see kiosks for Viettel, MobiFone, and Vinaphone in the arrivals hall.
- Price: Tourist bundles cost $20–$25 USD (500,000–625,000 VND) for 10–20GB.
- Pros: Most take Credit Cards/Apple Pay.
- Cons: You’re paying a 100% markup for convenience.
- Requirement: Bring your passport to register the SIM. That’s Vietnamese law for all carriers.
- Pro-tip: For a short 3-day trip, just buy it here and save your time. For longer stays, wait until you reach Duong Dong.

3. At your hotel
Hotels and guesthouses in Phu Quoc sometimes sell SIM cards for tourists. It is convenient but the price is expensive – equal to airport level or worse. This option is only worth it if you are genuinely stuck.
III. Getting an eSIM (get it before arrival)
If your phone supports eSIM, a Vietnam eSIM better alternative to physical one. Get the QR code by email within 5–10 minutes, install it at home, activate it when you land. Skip the airport kiosks and the passport registration hassle. You land in Phu Quoc already connected.
Most iPhones from XR onwards and Android flagships from 2020+ support eSIM. You check if your phone works with eSIM by using our updated eSIM compatible device list.

IV. Signal Dead Zones in Phu Quoc: What to Avoid
- Reliable Everywhere: Long Beach, Duong Dong, VinWonders, Hon Thom Cable Car, Night Market.
- Patchy (Viettel only):Ganh Dau, Bai Dai, National Park outer trails.
- Black Holes (No Signal): Deep National Park interior and the middle of the ocean between small islands.
💡 Pro-tip: Before heading anywhere remote, download Offline Maps for the whole island on Google Maps. It only takes 2 minutes and saves you when the signal drops mid-navigation.
V. Things you need to know for tourists to Phu Quoc
- If you already have a SIM before going to Phu Quoc, like Vietnam SIM bought in Hanoi or HCMC, it still works perfectly in Phu Quoc. Coverage follows the carrier nationally, not the city you bought it in.
- How much data do you actually need? 1–3GB/day covers maps, messaging, social media, and some streaming for most people. The 5GB/day plans are more than enough even if you’re posting everything to Instagram in real time.
- If you need more data during the Phu Quoc trip, you can find top-up cards at any Circle K and Winmart on the island.
- Every physical SIM requires a Passport Scan and a Live Photo at the counter (2026 Law). If a street vendor says you don’t need it, your SIM will likely be blocked in 48 hours.
For convenience and smooth experience of connectivity in Phu Quoc, eSIM is the best option if your phone supports it. If you are going to explore Phu Quoc’s wild north, grab a Viettel plan. If you come as part of a longer Vietnam trip, your existing SIM from Hanoi or HCMC already covers you.
