Internet in Dunedin for Tourists: eSIM, SIM Cards, WiFi and Mobile Data

Reliable internet in Dunedin helps tourists navigate the city, check local transport, confirm wildlife tours, contact accommodation and organise journeys around the Otago Peninsula and the wider South Island.

You can stay connected with a travel eSIM, a New Zealand prepaid SIM card, international roaming or public WiFi. The best option depends on your phone, trip length, expected data use and whether you need a New Zealand telephone number.

Quick answer: a travel eSIM is usually the easiest option for tourists who mainly need mobile data. Install it before departure, select it for Mobile Data after arriving in New Zealand and enable Data Roaming on the travel eSIM. Choose a local prepaid SIM when you need a New Zealand number, traditional calls or SMS.
