nextSIM does not offer plans that provide truly unlimited high‑speed data in Australia. Plans that include the word “Unlimited” in their name give only 1 GB or 2 GB of high‑speed data during their validity period, after which the speed is reduced to 512 kbps or 2000 kbps.
For travelers who need more data, nextSIM offers fixed‑data plans. A 100GB plan for 30 days costs $55.53 USD, and a 50GB plan for the same period costs $31.67 USD. These fixed‑data options can be more cost‑effective, especially for heavy data users, and are available in a range of other sizes and validity periods.
