MobiMatter eSIM Data Plans for Guernsey

MobiMatter does not offer an unlimited data eSIM plan for Guernsey. All of its Guernsey‑coverage plans have fixed data limits.
Instead, MobiMatter provides several fixed‑data options, for example the Europe Asia and USA 40GB Yearly plan, the Best World 25GB 90‑day plan, and the Europe Asia and USA 20GB 30‑day plan. Choosing one of these fixed plans can be more cost‑effective for most travelers unless the user is an extremely heavy data consumer.

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.
