GulfData does not provide a truly unlimited data eSIM for Australia. The plans that carry the “Unlimited” name give 1 GB per day at full speed, after which the speed is reduced to 512 kbps, so the data allowance is capped.
Travelers who need more data can choose fixed‑data plans. For example, GulfData offers a 50 GB plan valid for 30 days at $34.00 USD and a 20 GB plan valid for 30 days at $16.50 USD. These plans give a larger data allowance without the speed reduction that applies to the “Unlimited” plans.
