New Caledonia eSIM

Manageable, but prepare for it. English works at hotels and on the main tours, yet signs, menus and ferry or bus timetables are mostly in French. Download the French pack in a translation app for offline use, and save your accommodation address in French to show a driver.

Book before you fly. Domestic flights and ferries both have limited seats and fill quickly around holidays, and ferry schedules are adjusted for sea conditions. Leave a spare day before your international departure and check the sailing status on the morning of travel every time.

In Noumea the Taneo buses and walking are enough. Once you head up either coast of Grande Terre, public transport is sparse and the distances are long, so most visitors rent a car. Download offline maps first, because some of the mountain crossings have no service at all.

Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.

No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
