Forgetting what I have done in the past as its been a few years since last visit.
I need to get a SIM card with EU data roaming and fair amount of data (20-30GB). I've read past posts using search fxn and see that A1, Drei, and Magenta are my best bets. ....BUT all apparently need me to go to fixed store to register AND the cards I see offered are renewing every 28 days (not a self expiring card after sqy 2 weeks or 30 days which I know I have used in the past).
I just need the SIM for a couple weeks in AT and neighboring EU countries, and hope to avoid getting rebilled a monthly fee or having to go back to store to inactivate card (unless its easy to do online).
Any advice ???
