The Seychelles are a scatter of granite and coral islands in the Indian Ocean, a thousand miles from the African coast and outside every roaming zone there is. Install the eSIM before you fly and you are online from the arrivals hall on Mahé — and still online when the ferry reaches Praslin and La Digue.


Almost every visitor arrives at the international airport on Mahé, on the coast a few miles south of Victoria. Some stay on the island; many go straight on — by small plane or by fast ferry from the capital's harbour — to Praslin and then La Digue. Cruise ships call at Victoria too. Either way the first things you need are a transfer, a ferry ticket on your phone and a message to your guesthouse.

The Seychelles count more than a hundred islands, but nearly all the people, and nearly all the masts, are on three. On Mahé the coast road, Victoria, the airport and Beau Vallon have strong 4G; Praslin and La Digue are well covered around their villages, jetties and main beaches.
Granite is what gets in the way. In the mountain forest of Morne Seychellois, on the hiking trails, and on beaches walled in by boulders and steep hills — several of the famous ones — expect the signal to weaken or drop. On boat trips it fades as you leave the main islands, and the remote coral Outer Islands have little beyond what a resort provides itself.

The Seychelles are an independent republic in the middle of the Indian Ocean. No European roam-like-at-home rule reaches them, British and American plans treat them as a far-flung rest-of-world destination, and the daily passes that make other trips affordable often do not apply here or cost considerably more. This is the kind of place where a week of ordinary phone use can produce a memorable bill.
Cruise passengers should note that the ship's own cellular-at-sea network is a separate satellite service at maritime rates, which no land plan covers.
A travel eSIM takes the question away: a fixed price, paid before you leave, on a local network.
Island-hopping is the whole point of the Seychelles, and the crossings are where the signal goes. The fast ferry from Mahé to Praslin takes about an hour across open water and can be lively; the onward hop to La Digue is short. Expect to lose data in mid-crossing and pick it up again as the next island approaches.
Book ferry seats ahead in high season, keep the tickets saved on the phone rather than in your email, and download offline maps of all three islands before you leave the hotel Wi-Fi.
The trade winds swap sides during the year, and with them the seaweed, the waves and the currents: a beach that is glassy in one season can be rough in the other. Several of the most photographed — Grand Anse and Petite Anse on La Digue, Anse Intendance on Mahé — have strong currents and no lifeguard.
Check conditions locally before you swim, and keep in mind that these wilder beaches are also where the signal is weakest.
It will probably connect, but at rest-of-world rates. The Seychelles are outside the EU's roam-like-at-home area and outside the usual roaming bundles of British and American operators; where a daily pass exists it tends to sit in the most expensive band. Check the price list before you go — or use a travel eSIM.
Yes. A Seychelles plan works across the country wherever there is coverage, and all three main islands are well served around their villages and main beaches. Expect gaps on the ferry crossings, on forest trails and on beaches closed in by granite.
Yes, once you are ashore — switch data to the travel eSIM and it connects to the local network. At sea it will not work, and nor will any land plan: the ship's maritime network is the only signal on the open ocean, and it is billed separately and very expensively.
No — a Seychelles plan covers the Seychelles. Mauritius has its own plans, and if one trip takes in several Indian Ocean countries, a regional or global plan is the simpler choice.
Expect good 4G around Victoria, along the coasts of Mahé and in the villages of Praslin and La Digue. Whether a plan uses 5G is shown on each plan's card.
No. A local SIM means a queue at the airport counter, a passport registration and a number you will never use again. A travel eSIM is installed before you leave home, connects to a local network when you land, and leaves your own SIM in place for calls and bank codes.
One eSIM can cover Seychelles and the countries around it — no need to buy a plan at every border:
