Astaroam eSIM Data Plans for Guernsey

Astaroam does not offer any unlimited data eSIM plans for Guernsey. Travelers looking for a data plan with Astaroam will find fixed data options instead. For example, the Europe 20GB 30Days plan costs $68.56 USD and includes tethering with 5G coverage across Guernsey plus 40 other countries, while the Guernsey 20GB 30Days plan costs $72.35 USD and is available only in Guernsey.

Choosing a fixed data plan can be more cost‑effective for most users unless the traveler is an extremely heavy data consumer, in which case a larger allowance like 20GB may cover their needs for the duration of their visit.

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.
