ViaConecta does not provide a truly unlimited data eSIM for Australia. The plans that include “Unlimited” in their name actually give a fixed allowance of 1GB per day, after which the speed is reduced, so they are not unlimited.
Travelers can instead choose from fixed data plans that offer larger data allowances. For example, the Global 80GB 365‑day plan, the Australia 30GB 30‑day plan, or the Global 40GB 180‑day plan give a set amount of high‑speed data that must be used within the validity period. These fixed data plans can be more cost‑effective for most users unless they are extremely heavy data consumers.
