Astaroam eSIM Data Plans for Guernsey

Astaroam does not provide an unlimited data eSIM for Guernsey. All of its plans for the island feature a fixed data allowance and a 30‑day validity period.

If a fixed data plan better suits your needs, Astaroam offers several large‑capacity options. For example, the Europe 20GB 30Days plan gives 20GB of data for $69.77 USD, while the Guernsey 20GB 30Days plan offers the same amount of data for $73.62 USD. Other available plans include 10GB and 5GB packages for $41.69 and $24.43 USD respectively. Choosing a fixed data plan can be more cost effective unless you are an extremely heavy data consumer.

Astaroam does not provide an eSIM for Guernsey that includes a phone number or SMS capability. The provider only offers data‑only plans for that destination. Travelers can still use popular VoIP services such as WhatsApp, Telegram and iMessage over the data connection for calls and messaging, but there is no built‑in telephony feature with a local number or SMS support.

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.
