eSIMCard eSIM Data Plans for Guernsey

eSIMCard does not provide a true high‑speed unlimited data eSIM for Guernsey. The plans that carry “Unlimited” in the name actually give a fixed amount of high‑speed data—typically 1 GB or 2 GB per day—and the network throttles speed to 512kbps (or 2000kbps for “Unlimited Plus” plans) once that amount is consumed.
Customers who need more data can choose from fixed data plans that come with larger allowances, such as the 50 GB plan for 30 days at $31.39 or the 35 GB plans for the same period and price. These fixed‑data plans keep the full 5G speed until the data cap is reached, after which service stops. Choosing a fixed data plan can be more cost‑effective, especially for travelers who use data heavily but do not require true unlimited usage.

eSIMCard does not provide a Guernsey eSIM that includes a local phone number or SMS capability. Only data‑only plans are available for travel to Guernsey. Travelers can still use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages.

eSIMCard lists 30 data plans that cover Guernsey as a single‑country focus and 90 plans that include Guernsey as part of a multi‑country bundle. Among these options, providers offer both fixed data‑amount plans (77 in total) and daily data‑cap plans (43). The available packages range from as little as 1 GB to 500 GB of data, with prices ranging from roughly $3.41 to $395.07 and validity periods of 1 to 180 days, giving travelers a wide selection of choices suited to different usage needs.
