Is roaming free in Aland Islands with my UK or US SIM card?

For travelers with an EU SIM card, roaming in the Aland Islands is typically included under EU "Roam Like At Home" regulations, meaning you might not incur extra charges. However, if you're traveling with a UK or US SIM card, it's highly unlikely that roaming will be free. Your home carrier will almost certainly charge you expensive daily rates or per-MB fees for data, calls, and texts. Using an Aland Islands eSIM is a far more cost-effective and predictable solution. It gives you dedicated data access via local networks like Telia, letting you explore Eckerö without worrying about a huge phone bill upon your return.
