Yes, esimzon offers unlimited data eSIM plans for Austria. The plans are available with validity periods ranging from 1 day to 30 days and prices from $4.50 to $62.00. Each plan provides unlimited data, allows tethering, and has a maximum speed of 10000kbps; speeds may be throttled after heavy usage.
Because the plans are subject to a Fair Usage Policy, speeds can be reduced if data usage is high. Travelers who want to confirm the exact limits and typical data available at normal speed should contact esimzon directly.
