RedSim eSIM Data Plans for Guernsey

RedSim does not provide an unlimited data eSIM for Guernsey.
The provider offers fixed‑data plans that must be used within a 30‑day validity window, such as the Guernsey 20GB 30‑Days plan or the Guernsey 10GB 30‑Days plan. These fixed plans can be more cost‑effective for most travelers, unless a visitor requires a very high data volume that would exceed the fixed allowances.

RedSim does not provide eSIM plans for Guernsey that include a phone number or SMS capability. Only data‑only eSIM plans are available from this provider for the destination.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging. However, some destinations may block or restrict access to specific apps or VoIP services, so travelers should verify that the apps they rely on are accessible in Guernsey before purchasing.

RedSim offers four single‑country plans and five multi‑country plans for Guernsey. The plans range in price from about $4.23 to $62.70 and provide between 1 GB and 20 GB of data, with validity periods from 7 to 30 days. Some plans give a fixed data amount for the entire validity, while others may cap data usage on a daily basis, allowing users to manage consumption day by day.
