No, gosimless does not provide an unlimited data eSIM plan for Guernsey. Travelers who need large data allowances can choose from fixed‑data plans that are valid for a specified number of days.
For example, the 50GB plan is valid for 180 days and the 20GB plans are available for either 30 or 90 days. These fixed data plans typically offer a lower price per gigabyte than adding credit, making them a more cost‑effective option for most users unless they require truly unlimited data.
