Is <strong>Guernsey</strong> included in my UK or EU SIM card's roaming allowance?

A common pitfall for even the most seasoned flyers! Despite its close ties to the UK, Guernsey operates as a separate jurisdiction from both the UK and the EU. This means your standard 'Roam Like at Home' benefits from an EU SIM or typical UK carrier plans generally do not extend here. You could face hefty out-of-bundle roaming charges, a definite no-fly zone for your budget. eSIMFlyer offers a dedicated Guernsey plan, providing predictable, cost-effective data from the moment your aircraft touches down at Guernsey Airport (GCI), saving you from unexpected bill shock.
