Saily eSIM Data Plans for Guernsey

Saily does not have a truly unlimited data eSIM plan for Guernsey. The plans labeled “UNLIMITED” are actually fixed‑data offerings with a 30‑GB cap; once the cap is reached the speed drops to 1024 kbps. Travelers looking for high‑volume data can instead choose from several fixed‑data options, such as the Guernsey 10GB 30‑day plan at $29.99 USD, the Guernsey 5GB 30‑day plan at $16.99 USD, or the longer‑term Global 20GB 365‑day plan at $66.99 USD. These plans may be more cost‑effective for most users, unless a truly unlimited data experience is required.

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 provides four single‑country data plans for Guernsey and an additional six multi‑country plans that include Guernsey alongside other destinations.
Across all the offerings the price varies roughly from $4.99 to $66.99, with data caps ranging from 1 GB up to 30 GB.
The single‑country plans give users a dedicated data allowance for Guernsey only, while the multi‑country options bundle Guernsey with other covered locations, often at a lower per‑GB cost but with a shared data pool.
Some of the plans also include a “reduced speed” option of 1024 kbps, which applies to selected entries within the range.
