MobileSIM eSIM Data Plans for Australia

MobileSIM’s plans that include “Unlimited” in the name give customers 3GB of high‑speed data each day. After that limit is reached the speed drops to 1000kbps, so the plans do not provide truly unlimited high‑speed data for Australia.

Instead, MobileSIM offers several fixed‑data eSIM options for Australian travelers. Examples include a 10GB plan for 30 days priced at $18 and a 20GB plan for 30 days for $30, both of which deliver full‑speed data until the cap is reached. A Global 60GB plan for 125 days also covers Australia and may be preferable for users who need larger capacity. These fixed‑data plans can be more cost‑effective unless a user requires very high data consumption and would benefit from the higher daily limit offered by the “Unlimited” plans.

MobileSIM does not offer an eSIM plan for Australia that includes a phone number or SMS capability. The provider only supplies data‑only eSIM plans, so travelers must use data connections for messaging and calling through VoIP applications such as WhatsApp, Telegram, or iMessage.

MobileSIM lists 12 single‑country plans and 20 multi‑country plans for Australia. The available plans range from $2.30 to $165.00 in price and provide between 200 MB and 60 GB of data, with validity periods spanning 3 to 125 days. MobileSIM offers both daily‑cap and fixed‑cap data models; daily‑cap plans reset their data allowance each day, whereas fixed‑cap plans provide a total data quota for the entire validity period, and some plans include reduced speed once the cap is reached.
