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

Reliable internet in Christchurch helps tourists navigate the city, check local buses, contact accommodation, collect rental cars and plan journeys across the 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, travel style, trip length and whether you need a local telephone number.

Quick answer: a travel eSIM is usually the most convenient 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 prepaid SIM when you need a New Zealand number, traditional calls or SMS.
