Horizon eSIM eSIM Data Plans for Australia

Horizon eSIM does not provide an unlimited data eSIM for Australia. All of its Australian‑specific plans have a hard data cap, as shown in the data cap column of the provider’s offerings.

Travelers who need a large amount of data can choose from Horizon eSIM’s fixed data plans, such as the World 200 GB 360 days plan, the World 100 GB 360 days plan, the Australia 50 GB 180 days plan, the Australia 50 GB 30 days plan, or the World 50 GB 180 days plan. These fixed data plans offer substantial data allowances and can be more cost‑effective for most users unless they are extremely heavy data consumers.

In Australia, Horizon eSIM does not offer any eSIM plan that includes a phone number or SMS capability. Only data‑only plans are available. Travelers can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these apps are accessible in Australia before purchasing, as some destinations may block or restrict specific VoIP services.

Horizon eSIM offers 12 single‑country plans for Australia and 21 multi‑country plans that also cover Australia. Prices range from about $0.27 to $275.89, while data caps span from 100 MB to 200 GB. Single‑country plans provide a fixed amount of data for the plan’s validity, whereas multi‑country plans often use daily data caps that reset each day across the covered regions.
