AlpineSIM eSIM Data Plans for Guernsey

AlpineSIM does not provide an unlimited data eSIM for Guernsey. The provider’s available plans for the island all have specific data caps, such as 50GB for 180 days, 20GB for 30 days, 20GB for 90 days, and 10GB for 30 days. Each plan includes tethering and is delivered over a 5G network covering Guernsey.

Choosing a fixed data plan can be more economical unless a traveler expects to use very large amounts of data. Examples of the larger fixed plans are the 50GB 180‑day option and the 20GB 30‑day option, both of which give the user a sizable data allowance and a clear validity period.

AlpineSIM does not provide a Guernsey eSIM that includes a phone number or SMS capability; the provider offers only data‑only plans. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but should verify that those services are accessible in Guernsey before purchasing.

AlpineSIM lists 5 single‑country data plans and 32 multi‑country plans that cover Guernsey. The pricing for these options ranges from about $2.33 to $166.83, while the data caps vary from 500 MB up to 50 GB over validity periods that can be as short as one day or as long as 180 days. Some plans apply a daily data cap, delivering a fixed amount each day of the validity, whereas others offer a single, fixed amount that can be used at any point during the period. Many of the plans also allow tethering, enabling the data to be shared with other devices.
