Can I expect free roaming in Guernsey with my existing UK or EU SIM card?

It's a common misconception, but Guernsey, while a British Crown Dependency, operates independently of the UK and the European Union for telecommunications. This means that standard 'Roam Like at Home' benefits from your UK or EU carrier typically do not apply. You could incur significant roaming charges. For a worry-free and budget-friendly connection during your stay, a HotelESIM specifically for Guernsey is your ideal choice, offering clear, predictable costs and reliable service.
