Flysimio eSIM Data Plans for Guernsey

Flysimio does not offer an unlimited data eSIM for Guernsey.
The provider’s catalog contains fixed data plans that range from 1GB for 7 days up to 20GB for 30 days. Each plan has a set data allowance and a fixed validity period, and the data cap is hard‑capped until the plan expires. Travelers who need more data can choose the higher‑cap options, such as the 20GB 30days plan, or supplement usage with a pay‑as‑you‑go plan if available. Fixed data plans are generally more cost‑effective unless the traveler is an extremely heavy data consumer.

Flysimio does not provide eSIM plans for Guernsey that include a local phone number or SMS capability; only data‑only eSIMs are offered. Travelers who want to use messaging or voice apps can use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that those services are accessible and not blocked in Guernsey beforehand.

Flysimio offers five single‑country eSIM data plans for Guernsey and does not provide any multi‑country coverage plans for the island. The available plans range in price from roughly $7 to $84.48 USD and provide data caps between 1 GB and 20 GB, with validity periods that span 7 to 30 days. The plans are typically fixed‑data offerings, meaning the data allowance does not replenish daily but remains available for the entire validity window, and tethering is permitted on most of them.
