MobiMatter eSIM Data Plans for Guernsey

MobiMatter does not offer an unlimited data eSIM for Guernsey. The plans it offers for the island are fixed data plans with explicit caps. For example, the Europe Asia and USA 40 GB Yearly plan provides 40 GB of high‑speed data for 365 days and costs $59.99 USD, while the Best World 25 GB 90 Days plan gives 25 GB for 90 days at $69.99 USD. These fixed‑plan options can be more cost‑effective for most travelers unless they need very heavy data usage, in which case an unlimited plan would be preferable.

MobiMatter does not provide an eSIM plan for Guernsey that includes a phone number or SMS capability. The only plans available are data‑only eSIMs, which can be used with VoIP applications such as WhatsApp, Telegram, or iMessage for calls and messaging. Travelers should check that the apps they intend to use are accessible in Guernsey before purchasing.

MobiMatter offers 17 multi‑country data plans that include coverage of Guernsey, while no single‑country plans are listed. The available options range from about $3.99 to $67.49, with data caps between 1 GB and 40 GB, and validity periods spanning 7 to 365 days. Several plans allow tethering, enabling the data to be shared with other devices.
