The availability of free roaming in Finland depends on your SIM card's origin. For EU citizens, the 'Roam Like at Home' regulation generally applies. However, following Brexit, many UK-based carriers, including O2, Vodafone, and Three, have reinstated daily roaming charges for non-EU destinations like Finland. Travelers from countries outside the EU/EEA, such as the USA, Canada, or Asia, will invariably incur international roaming fees. CoreESIM offers a cost-effective alternative to avoid these variable charges.
