Can I expect free roaming in Hungary with my UK or US SIM card, or is SouthESIM a better option?

It truly depends on where your SIM card is from. Hungary is part of the EU, so 'Roam Like at Home' applies to EU citizens. However, if you're from the UK (post-Brexit), many major UK carriers such as O2, Vodafone, and Three have reintroduced daily roaming fees, which can quickly add up. For US travelers, plans like those from T-Mobile might offer basic roaming, but often with slower 2G speeds or costly daily passes. SouthESIM offers a straightforward, budget-friendly way to get fast data in Budapest and beyond without unexpected charges.
