ZenSim does not provide a truly unlimited data eSIM for Oceania. The only plans that carry the word โUnlimitedโ in their name are the Asia+ Unlimited STANDARD options, which actually allow 3GB of highโspeed data per day and then throttle traffic after that limit. These Asia+ plans are not intended for use in Oceania.
For travelers to Australia and NewโฏZealand, ZenSim offers fixed data plans such as the Oceaniaโฏ20GB plans for 10 or 30 days and the Oceaniaโฏ10GB 10โday plan. These options provide a large data allowance at a predictable price and are typically more costโeffective unless a user requires a large continuous data budget.
