RedEx eSIM does not provide a true unlimited‑data eSIM for Austria. All of its plans listed for Austria have a defined data cap, such as 2 GB, 3 GB, 100 GB, or 200 GB for a 30‑day period.
Travelers who need a large amount of high‑speed data can choose one of RedEx eSIM’s fixed data plans, for example the 200 GB plan or the 100 GB plan, both valid for 30 days. These plans offer a substantial data allowance and do not have a speed reduction after a low threshold. For lighter usage, shorter‑term plans with 1 GB, 2 GB, or 3 GB are also available and include tethering permission.
