Astaroam eSIM Data Plans for Guernsey

Astaroam does not provide an unlimited data eSIM for Guernsey. All of the plans listed for Guernsey have a fixed data cap, such as the Guernsey 20GB 30Days plan, the Europe 10GB 30Days plan, and the Guernsey 5GB 30Days plan, each with a 30‑day validity and 5G coverage.

If a traveler does not need unlimited data, a fixed data plan can be more cost‑effective, especially for moderate usage. For example, the Guernsey 20GB 30Days plan offers a larger data allowance at a higher price, while the Europe 5GB 30Days plan provides a smaller but cheaper option. These fixed plans are suitable for most visitors unless they are extremely heavy data users.

Astaroam does not provide a Guernsey eSIM that includes a phone number or SMS capability. Customers who purchase Astaroam plans for Guernsey receive only a data‑only eSIM.

While voice and text messages via a local phone number are unavailable, travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Because some destinations may block or restrict access to certain apps or VoIP services, travelers should confirm that the apps they need are available in Guernsey before buying a plan.

Astaroam lists five single‑country plans for Guernsey and five multi‑country plans that include the island. Prices range from just over $6 to about $74, while data allocations vary from 1 GB to 20 GB, all valid for between one and four weeks, and several plans allow tethering.
