Will the eSIM work on the ferry to Phu Quoc?

For much of the crossing, yes - you'll hold 4G near the mainland and island, with a weaker patch mid-sea. It's the national plan, so it reconnects automatically as you approach port.

Can I use it on the Nam Du islands?

Usually, on slow 4G, but it's the patchiest part of Kien Giang. Download maps, save your boat schedule and let photos upload once you're back on Phu Quoc or the mainland.

Good to know in Kien Giang

Ferries between Rach Gia, Ha Tien and Phu Quoc get cancelled in rough weather, so keep data on to check operator updates on Zalo and rebook through Baolau rather than queuing at the pier.

Best time to visit Kien Giang

November to March is dry, sunny and calm - peak beach season on Phu Quoc; the May-to-October wet season brings rougher seas and island ferry cancellations.

Two simple ways to buy

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.
