Avelis eSIM does not provide any plan with a data cap of unlimited for Oceania. The available plans for that region are fixed data plans, such as a 50GB bundle valid for 180 days and several 20GB bundles ranging from 30 to 90 days in validity. Each of these plans includes a set amount of data that must be used within the specified validity period and covers Australia and New Zealand (with some bundles extending to additional nearby countries).
Choosing a fixed data plan can be more cost‑effective for most travelers, especially if a user does not expect to consume very high volumes of data. For very heavy data users, a different pricing strategy might be more appropriate, but within Avelis eSIM’s Oceania offerings unlimited data is not available.
