simpleSIM does not provide an unlimited‑data eSIM specifically for Guernsey. All listed plans have a finite data cap, the largest being 50 GB for a 30‑day period.
Travelers who need a high‑capacity plan can choose from the fixed data options, such as the 50 GB eSIM Europe plan ($44.73 USD for 30 days) or the 20 GB eSIM Guernsey plan ($33.55 USD for 30 days). These fixed bundles are usually more cost‑effective for most users, unless the traveler expects to consume data well beyond the allotted amount.
