nextSIM eSIM Data Plans for Australia

nextSIM does not provide a truly unlimited high‑speed data eSIM for Australia. All plans that carry the “Unlimited” name in the provider’s catalog actually include a fixed data allowance, after which the speed is throttled to a reduced rate (512 kbps for the Standard tier, 2000 kbps for the Plus tier).

Travelers who need more data can use one of nextSIM’s fixed‑cap plans, such as the 100 GB 30‑day plan priced at $57.06 USD or the 50 GB 30‑day plan priced at $32.55 USD, both delivering full‑speed 3G/4G/5G service throughout Australia. These larger data packs offer a cost‑effective alternative for heavy data users who prefer a predictable data ceiling rather than a managed “unlimited” option.

nextSIM does not provide an Australia eSIM that includes a phone number or SMS capability. The provider only offers data‑only plans for the destination, meaning that travelers can use mobile broadband but cannot receive or send regular SMS or make traditional voice calls through a carrier number.

Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages, but these services do not rely on a local phone number.

nextSIM offers 33 single‑country plans for Australia and 55 multi‑country plans that include Australia. The single‑country options range from about $1.71 to $1, 269.33 USD, with data caps from 1 GB to 100 GB, while the multi‑country offerings are comparable in price and data ranges. Plans come in both fixed‑data and daily‑data‑cap variants; fixed‑data plans provide a set amount of data for the validity period, whereas daily‑data‑cap plans limit data usage each day. Overall, the price spectrum spans a few dollars to over a thousand dollars, and the data cap spectrum extends from a single gigabyte to one hundred gigabytes.
