nextSIM eSIM Data Plans for Australia

nextSIM does not provide a truly unlimited high‑speed data eSIM for Australia. Plans that carry the “Unlimited” name, such as the eSIM Unlimited Plus 1 Day Australia, give a fixed amount of high‑speed data—up to 2GB per day—but after that limit the speed drops to 2000kbps. Other Unlimited Standard plans supply 1 GB per day with the speed reduced to 512kbps once the cap is reached, which means the data is not truly unlimited.

For travelers who need a larger, non‑restricted data allowance, nextSIM offers fixed‑quantity plans. The eSIM 100GB 30 days Australia plan costs $54.98 USD and the eSIM 50GB 30 days Australia plan costs $31.37 USD. These fixed‑data options can be more cost‑effective for heavy data users than the scaled‑down Unlimited packages.

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 lists 36 single‑country data plans for Australia, covering data amounts from 1 GB to 100 GB at prices ranging from $1.68 to $1, 284.42. In addition, there are 83 multi‑country plans that include Australia, offering similar data ranges and price points. These plans come in two main styles: fixed‑data caps, where a set amount of data is allocated for the validity period, and daily‑cap plans, where a maximum amount of data can be used each day; roughly half of the offerings are fixed‑cap and the other half are daily‑cap styles.
