AdventureSIMs eSIM Data Plans for Guernsey

AdventureSIMs does not provide an unlimited‑data eSIM for Guernsey. All of their offerings for the island have a hard data cap, ranging from 10GB to 50GB, and come with fixed validity periods of 30 to 180 days.

If you need a large data allocation, you can choose one of AdventureSIMs’ fixed data plans. For example, the “Guernsey 20GB 30 Days” and the “Europe Complete 50GB 180 Days” plans give significant bandwidth and may be more cost‑effective for most travelers, especially those who are not exceptionally heavy data users.

AdventureSIMs does not offer a Guernsey eSIM plan with a local phone number or SMS capability. Their Guernsey plans are data‑only, so travelers will need to rely on VoIP or messaging apps over the data connection for calls and text. Apps such as WhatsApp, Telegram, and iMessage can usually be used in Guernsey, but availability can vary and should be confirmed before purchase.

AdventureSIMs offers five single‑country plans and eight multi‑country plans for Guernsey. The plans vary in price from roughly $4.75 to $92.78 and in data cap from 1 GB up to 50 GB. Validity periods range from 7 to 180 days, and several of the plans allow tethering.
