eSIMzio eSIM Data Plans for Guernsey

eSIMzio does not provide an unlimited data eSIM for Guernsey. The provider’s catalog for Guernsey consists of fixed data plans, each with a specified data cap and validity period. Examples include the Global 60 GB plan valid for 125 days, the Global 20 GB plan valid for 30 days, the Global 20 GB plan valid for 365 days, and the Global 10 GB plan valid for 30 days.

Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user expects to consume data at a very high rate. In that case, a larger data allowance such as the 60 GB plan may be preferable, but it still has a hard cap and a set validity window.

eSIMzio does not provide a Guernsey eSIM that includes a phone number or SMS capability. The provider only offers data‑only eSIM plans for Guernsey.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict these services. It is advisable to confirm that the apps you rely on are accessible in Guernsey before purchasing a plan.

eSIMzio offers 19 multi‑country data plans for Guernsey, with prices ranging from about $2.03 to $228.34 and data caps between 200 MB and 60 GB. All plans allow tethering, and no single‑country plans are available.
