French Polynesia is more than a hundred islands scattered across a stretch of the South Pacific as wide as Europe — Tahiti, Moorea, Bora Bora and a great many atolls where the supply ship is still an event. It is French, but not in the European Union, and roaming here is priced accordingly. Install the eSIM before you fly and you are online from the arrivals hall.


Every international flight lands at Faa'a, on Tahiti, a few minutes from the centre of Papeete; cruise ships dock on the town's waterfront. From here the country fans out: the ferry to Moorea leaves from the quay down the road, and the small planes to Bora Bora, the Tuamotus and the Marquesas from the domestic terminal next door. Connections are often tight, and a working phone helps.

On Tahiti the towns and the coast road that circles the island have solid 4G, strongest around Papeete. Moorea and Bora Bora are well covered around their shores, and the resort sandbars in Bora Bora's lagoon usually are too.
It fades where the people stop. Tahiti's interior valleys and the wild end of Tahiti Iti have little or nothing. On the Tuamotu atolls there is signal in the village and around the airstrip, and none across a lagoon that can be as big as a small sea. In the Marquesas each valley village has its mast and the ridges between them do not. Between islands, on the open ocean, there is no mobile network at all.

French Polynesia is a French overseas country, but it is not part of the European Union, and the EU's roam-like-at-home rules stop half a world short of it. A plan from Paris or Berlin roams here like any other foreign plan — and for most operators, European, British, American or Australian, this is one of the most expensive roaming zones on the list, often excluded from bundles and day passes altogether. A few minutes of background data can cost more than dinner.
A travel eSIM takes the question away: a fixed price, paid before you leave, on a local network.
The islands are a long way apart — the Marquesas are a flight of several hours from Papeete — and the further you go, the slower and patchier the connection tends to get. What takes a minute in town can take an evening on an atoll.
Before you leave Tahiti, download offline maps for every island on your route, your boarding passes and bookings, and anything you want to read or watch. On the outer islands, use the data for messages and keep the big files for later.
Cruise ships and some larger vessels carry their own maritime network, which takes over once the islands are out of range. A home SIM with roaming on will join it without asking, at rates that make even Pacific roaming look cheap.
Turn data roaming off on your home line and leave it on only for the travel eSIM, which connects to the Polynesian network when there is land in range and simply waits when there is not.
No. It is French, but outside the European Union, so roam-like-at-home does not apply — even to a plan from mainland France, unless that plan says so explicitly. Most European operators put it in their most expensive zone. Check your price list, or use a travel eSIM and skip the question.
Often it will connect, but seldom cheaply. French Polynesia is frequently left out of roaming bundles and day passes or placed in a high-priced zone, and some plans do not roam here at all. It depends on the operator — look the country up by name before you leave.
Yes. Both islands are covered around their coasts, including the ferry quay and villages on Moorea and the main island and most resort sandbars on Bora Bora. Expect it to weaken on mountain trails and far out on the lagoon, and to vanish on the open sea between islands.
No — the plan covers French Polynesia, across all its archipelagos wherever there is a network. New Zealand has its own plans, and for a Pacific cruise or a trip that combines several countries, look for a regional plan that lists each of them.
Count on 4G on Tahiti, Moorea and Bora Bora and in the main villages of the other islands, with slower service in the remotest places. Whether your plan uses 5G is shown on each plan's card.
The currency is the Pacific franc, which is tied to the euro. Cards are accepted at hotels, restaurants and shops on Tahiti, Moorea and Bora Bora; on the atolls and in the Marquesas, family guesthouses and snack bars often want cash, and cash machines are few — withdraw before you fly out.
