Saily eSIM Data Plans for Guernsey

Saily does not provide a truly unlimited data eSIM for Guernsey. The plans that carry the “UNLIMITED” label actually have a hard cap of 30GB; once that amount is reached the speed is throttled to 1000 kbps.

Travelers who need a large data allowance can choose from Saily’s fixed data plans for Guernsey, such as the 30GB plan valid for 90 days, the 20GB plan valid for 365 days, or the 15GB plan valid for 90 days. These fixed plans offer a set amount of high‑speed data and can be more cost‑effective for most users unless an extremely heavy data consumer is required.

Saily does not offer an eSIM for Guernsey that includes a phone number or SMS capability. The provider only sells data‑only plans in this destination. 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 certain apps, so it is advisable to check that the services you rely on are accessible in Guernsey before purchasing.

Saily offers four single‑country plans that cover Guernsey and eleven multi‑country plans that include Guernsey as part of a broader regional package. The plans vary from 1 GB to 30 GB of data, cost between roughly 4.99 USD and 159.99 USD, and are valid from 7 days to 365 days.
