MTX Connect does not provide an unlimited‑data eSIM for Oceania. The provider offers fixed data plans instead, such as 10 GB for 30 days, 4 GB for 14 days, and 2 GB for 7 days. These plans have a hard data cap and a defined validity period. Choosing one of these fixed data plans can be more cost‑effective for travelers unless they require large amounts of data beyond the available allowances.
