Vanuatu is a chain of some eighty islands in the South Pacific: blue holes, wreck dives, kava bars and a volcano you can walk up to after dinner. It sits outside most roaming bundles, so install the eSIM before you fly and you are online from the moment the doors open at Port Vila.


Most visitors fly into Port Vila on Efate from Australia, New Zealand, Fiji or New Caledonia; a few land directly at Luganville on Espiritu Santo, and a great many step off a cruise ship for the day. The airport is a short drive from town and the buses are unmarked minivans, so a map and a way to message your hotel are worth having from the first minute.

Port Vila and most of the ring road around Efate have good 4G, and so does Luganville and the east-coast road on Espiritu Santo. On Tanna, expect signal around Lenakel and the airport and a weaker one across the island.
Beyond those three, coverage thins out fast. The outer islands — Pentecost, Ambrym, Malekula, the Banks — usually have signal near the main villages and airstrips and none in the bush or on the far coasts, and what there is can be slow. Between the islands, at sea, there is nothing.

Vanuatu is a small island market far from anywhere, and home operators price it accordingly: usually in the most expensive roaming band, and frequently excluded from "worldwide" and Pacific passes that happily cover Fiji or Australia. Check your price list before you switch roaming on at the airport.
A local SIM is possible in Port Vila, with a queue, a passport and a registration form — a poor use of a cruise day. Resort Wi-Fi tends to be slow once everyone is back from the beach.
A travel eSIM takes the question away: a fixed price, paid before you leave, on a local network.
The wet season, roughly November to April, is also cyclone season, and a big storm can close airports and take down power and phone masts for days on the affected islands. Travel insurance that covers weather disruption is worth having, and so is a flexible last night in Port Vila before your flight home.
Keep a power bank charged, and save offline maps and your bookings while the signal is good.
Volcano visits on Tanna run in the late afternoon so that you are on the rim after dark. Access depends on the activity level that day, and guides will keep you back or cancel when it rises. Bring a torch, a warm layer, closed shoes and something to cover the camera from ash.
Signal at the crater is weak at best: message your lodge and download anything you need in Lenakel.
It may connect, and it will rarely be cheap. Most operators put Vanuatu in their top roaming band and leave it out of daily passes and "worldwide" bundles. Check your own price list before you land — or use a travel eSIM and know the cost in advance.
Do not count on it. There is usually coverage around Lenakel and along Tanna's west coast, but on the ash plain and the crater rim it is faint or absent, and it can drop out altogether when ash or weather affects the mast. Make your arrangements before you set off.
Expect 4G in Port Vila, Luganville and the main settled areas, and slower data on the outer islands. Whether your plan uses 5G is shown on each plan's card.
No — a Vanuatu plan covers Vanuatu. Fiji has its own plans, and if you are island-hopping across the South Pacific or stopping in Australia on the way, a regional plan is the simpler choice.
No. Buying one means finding a shop in Port Vila, queuing with your passport and registering the card, which is a large slice of a short day. An eSIM installed at home connects as the ship comes alongside; turn roaming off on your home line so it does not use the ship's own expensive network at sea.
In Port Vila, less than you might think — hotels, restaurants and tour operators take cards. Everywhere else, yes: the currency is the vatu, and markets, minibuses, village entry fees and outer-island bungalows are cash only. Cash machines are found in Port Vila and Luganville and are scarce beyond them.
One eSIM can cover Vanuatu and the countries around it — no need to buy a plan at every border:
Where the signal is, how roaming treats the place, and what to know before you land.
