Saily eSIM Data Plans for Guernsey

Saily does not provide a truly unlimited data eSIM for Guernsey. Plan names that include “UNLIMITED” actually grant a fixed data allowance of 30GB; once that limit is reached the data speed is reduced to either 1024kbps or 1kbps.

Travelers who need more data can choose from Saily’s fixed‑data plans, such as 30GB for 30 days or 90 days, 20GB for 365 days, and 15GB for 90 days. These fixed‑data options are typically more cost‑effective for most users unless a traveller expects to use data well beyond 30GB during the trip.

Saily does not provide a Guernsey eSIM that includes a phone number or SMS capability. Only data‑only eSIMs are offered for Guernsey. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calling and messaging.

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.
