Setting up your eSIM? The installation and activation guide walks through it step by step, and the full FAQ covers device compatibility, hotspot, dual SIM and topping up.

Two seasons and they matter. The dry season runs November to April, hot and bright at 26-32C, and is the reason to come. The wet season, May to October, brings heavy afternoon rain, rough seas and cancelled boat trips
Phu Quoc runs on Viettel, Vinaphone and Mobifone, and your eSIM rides one of them as its host. Vietnamese mobile data is fast and among the cheapest anywhere, and coverage along the island's developed west coast is good - our Ho Chi Minh City and Da Nang guides cover Vietnamese networks and the remote-working question in more detail. The thing that makes Phu Quoc genuinely different from anywhere else in Vietnam is not the network. It is that the island has its own immigration rules, and they are unusually generous and unusually easy to break by accident.
This is the single most useful thing to know about the island, and it is specific to here.
All nationalities get 30 days visa-free on Phu Quoc. Not a subset, not a list - everyone, without a visa, without a fee and without an application. It has been the case since 2020 and it flows from the island's status as a special economic zone.
You must arrive directly. An international flight or sea arrival straight to Phu Quoc qualifies. Transiting airside through Hanoi or Ho Chi Minh City is fine, provided you do not clear mainland immigration.
And you must stay on the island. The exemption covers Phu Quoc only. The moment you travel to the Vietnamese mainland you need a proper visa, and this is where people come unstuck - a day trip to Ha Tien or a couple of nights in Saigon on the way home is not covered by it.
Passport validity of at least six months is required as usual.
If you want mainland Vietnam too, get the standard Vietnamese e-visa before you fly and ignore the exemption entirely. It is inexpensive and removes the whole question.
Check the current position before booking. Vietnam has adjusted its visa rules repeatedly in recent years, and while this exemption has been stable, it is a policy rather than a treaty.
Worth knowing so the photographs you booked from match what you find.
Phu Quoc is developing extremely fast. The south of the island in particular has gone from fishing villages to large resort complexes in about a decade, and construction is visible and audible in places.
Vietnam is hosting APEC on the island in 2027, and infrastructure work has accelerated sharply towards that.
What this means practically: some beaches are quiet and beautiful, others sit next to a building site, and the gap between a listing photograph and the current view can be wide. Read recent reviews rather than the gallery.
The north is still relatively undeveloped, and Phu Quoc National Park covers more than half the island - it is a UNESCO Biosphere Reserve and the forest is genuinely protected.
The cable car to Hon Thom is the longest over-sea cable car in the world at nearly eight kilometres, and the ride is worth doing for the view over the An Thoi archipelago even if the theme park at the end is not your thing.
The west coast strip - Duong Dong, Long Beach, Ong Lang - is well covered, as is the south around An Thoi and Sunset Town.
The national park in the north and centre thins quickly on the forest tracks.
The east coast is quieter and patchier, including some of the better beaches.
On the water, island-hopping boats to the An Thoi archipelago drop in and out; the cable car itself has coverage for much of its span, which is a strange place to have bars.
In the wet season, heavy rain and storms degrade things temporarily, and power cuts are not unusual.
Download offline maps. Island roads are improving fast, which means mapping data is often out of date in both directions - roads that exist and are not shown, and roads shown that are building sites.
The currency is the dong, and the numbers are large - a mid-range meal runs into the hundreds of thousands. Watch the zeroes.
Cards work at resorts and larger restaurants, and cash is what everything else runs on. ATMs are widespread in Duong Dong.
Vietnamese QR payments dominate locally but generally need a local bank account.
Bargaining is expected at markets and with unmetered taxis; Grab operates on the island and removes the question.
As for the sauce: Phu Quoc fish sauce is a protected designation of origin in the EU, one of very few Asian products to hold that status. It is made from anchovies caught in these waters and fermented in wooden barrels for a year, and the distilleries in Duong Dong will show you the barrels. A bottle is the island's genuine souvenir - buy it at the source, and pack it very carefully.
Phu Quoc International (PQC) sits in the south of the island and has been substantially expanded. Direct international flights come from across Asia and seasonally from further afield, which is what makes the visa exemption usable.
Domestic flights from Hanoi and Ho Chi Minh City are frequent and cheap - but note that arriving on a domestic flight means you have already cleared mainland immigration and the exemption does not apply.
Fast ferries run from Ha Tien and Rach Gia on the mainland, and take two to three hours.
On the island, taxis and Grab cover everything. Renting a motorbike is common and the roads are better than they were, though traffic and construction traffic make it less relaxed than it looks.
Modest. Resort wifi is generally good, the island is small, and Vietnamese data is cheap enough that there is no reason to buy tightly. Where it earns its place is maps and Grab, both of which run constantly if you are exploring rather than sitting on a beach.
Beach clothes and very little else, most of the time.
Something covering shoulders and knees for the pagodas and for Duong Dong town, which is a working Vietnamese town rather than a resort.
Reef shoes for the rockier beaches and for boat landings.
A rain shell in the wet season, which arrives in the afternoon and is torrential rather than persistent.
Serious sun protection. You are ten degrees north of the equator.
Long sleeves for the evening in the forest and near water, for mosquitoes.
Sao Beach, the white crescent on the southeast coast, early before the day boats.
The Hon Thom cable car, from the gondola, over the fishing boats and the strung-out islands beneath.
Sunset Town at An Thoi, the built-from-scratch Mediterranean-style development, which is either charming or bizarre and photographs well either way.
Fishing boats at Ham Ninh on the east coast, at dawn.
Duong Dong night market, for the seafood and the noise.
A fish sauce distillery, with its rows of enormous wooden barrels.
Ganh Dau, the northwest headland, where you can see Cambodia across the water.
The pepper farms inland, with their rows of climbing vines.
Phu Quoc is closer to Cambodia than to mainland Vietnam, sitting in the Gulf of Thailand a few kilometres off the Cambodian coast.
Its fish sauce has EU protected designation of origin status, which puts it in the same legal category as Champagne and Parma ham.
The Phu Quoc ridgeback is one of only three ridgeback dog breeds in the world, alongside the Rhodesian and the Thai, and they are still bred on the island.
More than half the island is national park and UNESCO biosphere reserve, which is why the north still looks the way it does.
The Hon Thom cable car is the longest over-sea cable car on the planet, at close to eight kilometres.
And the island grows some of Vietnam's best black pepper, on farms you can visit, which is a considerably less glamorous export than the sauce and just as good.
Tet, the Vietnamese lunar new year in January or February, when the island fills with domestic visitors and much closes for several days.
The dry season, November to April, is the whole tourist calendar - calm seas, reliable sun and every boat trip running.
The wet season, May to October, brings heavy rain, rough water and cancelled crossings, and prices fall accordingly.
APEC in 2027 will bring significant disruption and infrastructure work in the run-up.
The love: Phu Quoc gives you genuinely good beaches, warm clear water, excellent and very cheap seafood, and an immigration rule that lets anyone in the world turn up for a month without paperwork. The national park in the north is real forest, the island-hopping in the south is excellent, the fish sauce and pepper are world-class products with actual provenance, and the whole place is inexpensive by regional standards.
The complaints are consistent and worth taking seriously. The construction is extensive and some resorts sit beside it. The development is fast and uneven, and parts of the island now look like a building site with a beach attached. Some beaches have litter, particularly after the wet season. It is not "undiscovered" despite being marketed that way. The wet season genuinely ruins trips if you book without checking. And visitors comparing it to Thailand's islands often find it less polished in service and infrastructure.
Come between December and March, stay north of Duong Dong if you want quiet, take the cable car, and buy the fish sauce at the distillery.
Not if you fly or sail in directly and stay only on the island - all nationalities get 30 days visa-free under the island's special economic zone status. Transiting airside through Hanoi or Ho Chi Minh City is fine. But the exemption covers Phu Quoc only, so any travel to mainland Vietnam needs a proper visa, and arriving on a domestic flight means you already cleared mainland immigration and it does not apply.
Yes. Vietnamese data is fast and among the cheapest in the world, and the developed west coast and south are well covered. The national park, the east coast and boat trips are where it thins. Download offline maps, because the island's roads are changing faster than mapping data can keep up.
The eSIM will, since it is a Vietnamese network either way. The visa is the problem, not the phone - the Phu Quoc exemption does not extend to the mainland, so plan a proper e-visa if the trip includes both.
For a beach holiday, largely yes. The argument for data here is Grab and offline-resistant navigation while you are moving around an island where the roads are actively being rebuilt.
