eSIMCard’s “Unlimited” eSIMs for Australia actually provide a fixed data allowance that is capped at 1 GB per day for regular plans and 2 GB per day for the “Unlimited Plus” variants. Once the daily limit is reached the connection speed drops to a reduced rate (500 kbps or 512 kbps for standard plans, 2000 kbps for Plus plans). Because the data volume is limited and speeds are throttled after the cap is hit, these plans are not truly unlimited high‑speed data options.
If a traveler needs more than 1 GB or 2 GB of data for an extended stay, eSIMCard offers fixed‑data plans that provide larger allowances without throttling. For example, a 100 GB plan is available for 180 days, and a 50 GB plan for 90 days, both unthrottled and suitable for heavy data usage. These fixed‑data plans can be more cost‑effective for users who expect to consume more data than the capped “Unlimited” plans allow.
