ChillaxSIM does not provide a truly unlimited data eSIM for Austria. All of its so‑called unlimited plans limit usage to 1GB per day. Once that limit is reached, the connection speed drops to a reduced speed of 5120kbps. The plans are available for various validity periods—from 3 days up to 30 days—and all include tethering.
Travelers who need more data can choose one of ChillaxSIM’s fixed‑data plans. For example, the Orange Europe (51 countries) Total plan offers 20GB, 50GB or 100GB of data for 30 days, with a reduced speed of 128kbps after the allowance is used. The O2 Europe (48 Countries) plan gives 35GB for 30 days, also with a throttled speed of 128kbps. These fixed‑data options may be more cost‑effective for heavy data users than the daily‑limit “unlimited” plans.
