AlpineSIM eSIM Data Plans for Guernsey

AlpineSIM does not provide an unlimited‑data eSIM for Guernsey. All of its Guernsey‑specific offerings have fixed data caps, such as a 20GB plan valid for 30 days or a 50GB plan valid for 180 days, with 5G coverage in Guernsey and a nearby network of 40 countries. If more data is required, the fixed‑data plans can be more cost‑effective than the lower‑capacity “Unlimited” variations that only provide a fixed amount of high‑speed data per day.

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.
