This specific WestESIM plan is exclusively provisioned for use within Jersey. The 'Bailiwick of Jersey' and the 'Bailiwick of Guernsey' are distinct jurisdictions with separate mobile network infrastructures. Should your travel plans include visiting Guernsey, you will need a separate eSIM plan tailored for that location. We encourage you to review our comprehensive range of eSIM options to find a suitable solution for multi-island itineraries within the Channel Islands.
