Astaroam eSIM Data Plans for Guernsey

Astaroam does not provide an unlimited data eSIM plan for Guernsey.
Customers who need data while visiting Guernsey can choose from a selection of fixed‑data plans.
For example, the Guernsey 20GB 30Days plan offers 20GB of high‑speed data for 30 days at $41.54 USD, and the Europe 20GB 30Days plan is available for $39.39 USD, covering Guernsey and 40 additional European countries. These fixed plans are typically more cost‑effective for most travelers unless extremely heavy data usage is anticipated.

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.
