Can I expect free roaming in Guernsey if I'm using my regular UK or EU SIM card?

This is a common misconception for many travelers! Despite its close ties to the UK, Guernsey operates its own telecom networks and is not part of the EU's "Roam Like at Home" scheme. This means your standard UK or EU mobile plan will likely incur significant roaming charges. To avoid any bill shock and enjoy reliable, budget-friendly data, a SouthESIM plan for Guernsey is a smart choice for staying connected without the worry.
