eSIM for Phu Quoc
Phu Quoc is Vietnam's largest island, off the southern coast in the Gulf of Thailand, with resort beaches, fishing towns and a national park interior. The main towns of Duong Dong and An Thoi are well covered, but the island's northern and eastern roads have more limited infrastructure, where Viettel performs best.
An eSIM Vietnam gives you access to the same plans in Phu Quoc as in the rest of the country. 5 GB is generally enough for maps, messaging and social media, while video streaming and hotspot use require more data. The plans shown range from 1 to 20 GB and start at $1.90. They are fully refundable within 30 days provided the eSIM has not been used on a network at the destination. The activation link is sent by email after purchase.
Getting connected in Phu Quoc
Phu Quoc has an international airport with direct flights from the mainland and abroad, so most arrive by air into well-covered territory and an eSIM activated beforehand has you connected on landing. You can book a Grab or resort transfer straight away. The main resort areas are well covered; if you plan to explore the quieter north or the national park, download offline maps for the less developed roads where signal thins.

Coverage in Phu Quoc
Phu Quoc's developed areas are well connected. Duong Dong, the main town, and An Thoi in the south, plus the Long Beach resort strip and the Sunset Town area, all have strong 4G with 5G in the main areas on all networks. VNPT and Vinaphone cover the resort areas well too. The island's character changes in the north and east: the national park interior, the quieter beaches like Bai Sao and Bai Thom, and the less developed northern and eastern roads have more limited infrastructure, where Viettel performs best. The cable car to Hon Thom and the boat trips to the An Thoi archipelago lose signal over open water.
Best network here
All networks fine in the towns; Viettel best on the northern and eastern roads
| Area | Best network | What to expect |
|---|---|---|
| Duong Dong (main town) | Viettel / Vinaphone | Strong 4G and 5G across the main town and night market. |
| Long Beach resort strip | Viettel / Vinaphone | Good coverage along the main west-coast resort beach. |
| An Thoi / Sunset Town | Viettel / Vinaphone | Reliable in the south near the cable car and harbour. |
| Northern roads / Bai Thom | Viettel | Less developed north; Viettel performs best where others thin. |
| Eastern roads / Bai Sao | Viettel | Quieter east-coast beaches; Viettel the steadier network. |
| Cable car / An Thoi islands | Viettel | Signal drops over open water on the cable car and island boats. |
Where to stay and connect in Phu Quoc
Long Beach (Duong Dong)
The main resort strip on the west coast near the town, with the best coverage and sunset views. A comfortable, well-connected base for most visitors.
Duong Dong town
The island's main town with the night market and harbour, reliably covered. A more local, practical base near the beach.
An Thoi / Sunset Town
The developed south with the cable car, Sunset Town and harbour, well covered. The base for the An Thoi island trips.
North / Ong Lang
Quieter beaches and eco-resorts in the less developed north. Scenic and calm, but coverage is Viettel-dependent on the northern roads.
Staying online while you move
Around the developed west coast and the main towns, coverage is good on all networks and Grab keeps you connected. The island is large, and the north and east are where it thins: the national park interior, the quieter beaches and the less developed roads favour Viettel, especially on the island's northern and eastern routes where infrastructure is more limited. The cable car to Hon Thom and the boat trips to the An Thoi archipelago for snorkelling lose signal over open water. For exploring the north or island-hopping, an eSIM on Viettel plus offline maps is the safe combination.
How much data in Phu Quoc
A beach holiday on Phu Quoc runs on 6 to 8 GB, mostly in the well-covered west coast and towns. Exploring the quieter north and east, or island-hopping the An Thoi archipelago, is where coverage thins, so a Viettel-based eSIM helps and offline maps matter for the northern roads. Use the resort coverage for uploads, and treat the snorkelling boat trips as partly offline over open water.

Phu Quoc eSIM FAQ
Is there good mobile coverage on Phu Quoc?
Yes, in the developed areas. Duong Dong, An Thoi, Long Beach and Sunset Town all have strong 4G with 5G in the main areas on all networks. The quieter northern and eastern roads have more limited infrastructure, where Viettel performs best.
Which network is best on Phu Quoc?
All networks are fine in the towns and resort areas. Viettel performs best on the island's less developed northern and eastern roads, where other networks are usable in towns but inconsistent outside them.
Will I have signal on the cable car or An Thoi island trips?
It drops over open water. The Hon Thom cable car and the boat trips to the An Thoi archipelago lose signal offshore, returning near the islands. Viettel reconnects best. Prepare offline before these trips.

How much data do I need on Phu Quoc?
6 to 8 GB covers a beach holiday. Most data is used in the well-covered west coast and towns; exploring the north and island-hopping lean on Viettel and offline maps more than extra volume.
Is Phu Quoc well covered for an island?
The developed west coast and main towns are well covered on all networks, better than many islands. The difference is the large, less developed north and east, where Viettel is the reliable choice as infrastructure thins.
