That's a common query, especially with changing roaming rules! If you're using a SIM from the UK or US, free roaming in Austria is unlikely. Post-Brexit, many UK carriers (like Vodafone or EE) have reintroduced daily roaming charges. For US carriers (like T-Mobile or AT&T), international roaming usually comes with hefty daily fees or expensive pay-per-use rates. This is precisely why a SouthESIM is a budget-friendly choice, giving you affordable data without those surprise charges when exploring places like beautiful Austria.
