Root Cause
Under the EU 'roam like at home' rules, SIMs issued in any EU/EEA country work in Austria at domestic prices - calls, SMS and data incur no roaming surcharge (fair-use caps can apply to data on unlimited plans). Buying a new SIM per country is unnecessary for EU/EEA SIM holders; non-EU visitors need only one EU/EEA SIM or eSIM for the whole bloc.
genericWorkarounds
-
90% success EU/EEA SIM holders: just enable roaming and check your plan's fair-use data allowance; non-EU visitors: buy ONE EU/EEA SIM or eSIM for the whole trip
Check the operator's roaming fair-use terms before departure. A single EU/EEA prepaid SIM or travel eSIM covers all EU/EEA countries at domestic rates - no per-country SIM churn.

Dead Ends
Common approaches that don't work:
-
Buy a separate local SIM for Austria while already holding an EU/EEA SIM
70% fail
Roam-like-at-home has applied across the EU/EEA since 2017 (extended to 2032): domestic-rate calls, SMS and data follow your SIM across the bloc, so the extra SIM costs money and a new number for nothing.
-
Assume unlimited home data roams without limits, or that the rule covers non-EEA SIMs
60% fail
Operators may apply fair-use data caps abroad on unlimited/cheap plans (with small surcharges beyond the cap), and the regulation only binds EU/EEA-issued SIMs - US/Asian SIMs get no protection. Switzerland and the UK are outside the scheme.
