Does my home SIM card (e.g., from the UK or US) offer free roaming in Greece, or should I use SouthESIM?

It’s a common misconception that roaming is free! For many UK travelers post-Brexit, carriers like O2 or EE have reintroduced daily roaming charges for Greece, which can add up quickly. Similarly, US carriers such as AT&T often have expensive daily passes or per-MB rates that aren't very budget-friendly. SouthESIM offers a much more affordable and predictable way to stay connected in Greece, letting you enjoy your trip without worrying about surprise roaming bills from your home provider.
