AlpineSIM eSIM Data Plans for Guernsey

AlpineSIM does not provide a truly unlimited data eSIM for Guernsey. The plans that list “Unlimited” in their names give a fixed amount of high‑speed data per day (for example 500MB/day or 1GB/day). After the daily quota is reached the speed is reduced, so the data are not unlimited.

Travelers who need high data volumes can choose one of AlpineSIM’s fixed‑data plans, such as the 20GB plan for 30 days or the 50GB plan for 180 days, both of which are available for Guernsey. These options give a larger data allowance without the throttle applied to the “Unlimited” plans.

AlpineSIM does not sell a Guernsey eSIM that includes a phone number or SMS capability. The provider offers only data‑only eSIMs for Guernsey. Travelers who need to communicate while abroad can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which provide voice and messaging without the need for a local phone number or SMS service.

AlpineSIM offers five single‑country plans and thirty‑two multi‑country plans for users travelling to Guernsey. The available plans cover a price range from about $2.28 to $164.19 and a data cap range from 500 MB up to 50 GB. Within these options, users can choose either fixed‑data plans that provide a set amount of data for the validity period or daily‑data‑cap plans that allow a maximum data amount each day.
