Great question for island-hoppers! Our specific SouthESIM plan for Guernsey is designed to keep you connected within its unique network. The Bailiwick of Guernsey and the Bailiwick of Jersey are distinct jurisdictions with separate mobile networks. If your adventure includes a trip to Jersey, you'll want to either look for a multi-island SouthESIM bundle (if available) or pick up a separate plan for Jersey to ensure continuous, affordable data across both beautiful islands.
