eSIM Mayotte

Mayotte is a French overseas department in the Indian Ocean between Madagascar and the Mozambique coast — an archipelago of two main islands enclosing the world's largest lagoon, with a fringing coral reef that is among the healthiest in the Indian Ocean. Orange provides 4G and 5G coverage across the island, and as an EU overseas department, all EU digital services work normally. Data is essential for navigating the complex lagoon boat tours, booking trips to the sandbar of Saziley, and using maps for the forest hikes on the extinct volcano Bénara.

Orange's 4G/5G covers Mamoudzou (the main town on Grande-Terre), Dzaoudzi (the prefecture capital on Petite-Terre), and the main coastal roads. The Bénara volcano (660m — the highest point) has coverage at the trailhead and partial coverage on the ascent. The mangrove forests around M'tsangamouji have coverage near the water.

Mayotte's lagoon — 1,100 km² of protected water — is one of the world's best snorkelling and diving destinations. The dive operators in Bandraboua and the main beach areas all have Orange coverage. The distant lagoon islets (Ilot de Sable Blanc, the white sand atoll) have no coverage — download offline nautical charts before departure.

Grande-Terre's interior roads through the ylang-ylang plantations (Mayotte supplies a significant share of the world's ylang-ylang essential oil) have basic coverage. The weekly market in Mamoudzou is well-covered and a compelling cultural experience.

Mayotte uses the Euro. French is the official language and Shimaore is widely spoken. The island has notable demographic complexity — a large migrant population and the EU's highest birth rate per capita.
