AlpineSIM eSIM Data Plans for Guernsey

AlpineSIM does not offer a truly unlimited high‑speed eSIM plan for Guernsey. The only “Unlimited Europe” plans listed provide a capped daily allowance such as 500MB/day or 1GB/day; once that daily quota is used the speed is throttled. Because of this cap, the plans are not considered unlimited data.

Instead, AlpineSIM offers fixed‑data eSIM options for travelers to Guernsey. For example, a 20GB plan valid for 30 days costs $40.55 USD, and a larger 50GB plan for 180 days is priced at $93.62 USD. These plans give a predictable high‑speed data allowance and can be more cost‑effective for users who plan to consume significant amounts of data.

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 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.
