CoreESIM's Australia-specific data plans are geo-restricted to the Australian continent. Service is not provisioned for use in New Zealand. Should your itinerary include travel from Sydney to Auckland, or transit through other nations like Singapore or Indonesia, your Australian eSIM will cease to function outside its designated coverage area. For multi-country journeys encompassing both Australia and New Zealand, CoreESIM recommends exploring our regional Oceania or global eSIM options for seamless cross-border connectivity.
