Which SIM card is best for Phu Quoc?

Viettel has the widest coverage across Phu Quoc, including the north and remote beaches, so it is the safest choice for travellers who ride around the island. Vinaphone and Mobifone also work well in Duong Dong and Long Beach.

Where can I buy a SIM card in Phu Quoc?

You can buy a tourist SIM at Phu Quoc Airport arrivals, at official Viettel/Vinaphone/Mobifone shops in Duong Dong, and at many convenience stores. Bring your passport — registration is required. A data-heavy tourist package usually costs 100,000-200,000 VND.

Can I use an eSIM in Phu Quoc?

Yes. If your phone supports eSIM, apps like Airalo or Holafly let you buy a Vietnam data plan before you arrive and connect on landing — convenient, though often pricier per GB than a local physical SIM.

SIM Card & Internet in Phu Quoc — The 2026 Guide

By Alex Nguyen · Updated May 2026 · 5 min read

A working data connection makes Phu Quoc far easier — for maps while you ride around the island, for booking and for messaging us on WhatsApp. Here is how to get online quickly and cheaply.

Best network: Viettel

Viettel has the strongest, widest coverage on Phu Quoc — including the northern roads and remote beaches where other networks weaken. If you plan to explore beyond town, Viettel is the safest pick. Vinaphone and Mobifone are also fine around Duong Dong and Long Beach. All three offer cheap, data-heavy tourist packages.

Where to buy & how much

At the airport: SIM counters in arrivals — quickest option, slightly higher price.
Official shops in Duong Dong: best prices and proper registration.
Convenience stores: widely available across the island.

Expect to pay roughly 100,000-200,000 VND ($4-$8) for a tourist package with plenty of high-speed data for a week or two. Bring your passport — SIM registration is legally required in Vietnam.

eSIM — connect before you land

If your phone supports eSIM, apps like Airalo or Holafly let you buy a Vietnam plan in advance and connect the moment you arrive — handy for getting your airport bike delivery sorted without hunting for a SIM counter. It is convenient but usually costs more per GB than a local SIM.

Staying online while you ride

Download Google Maps offline for Phu Quoc before you set off, mount your phone on the handlebars (we include a holder with every rental), and you will have navigation even in patchy-signal areas up north. WiFi is common in hotels, cafés and restaurants, but mobile data is what keeps you moving on the road.
