Spark Roam eSIM Data Plans for Guernsey

Spark Roam does not provide an unlimited‑data eSIM for Guernsey. Instead, the provider offers fixed data plans that cover the destination, such as a 50 GB plan valid for 180 days or a 20 GB plan valid for 30 days. These options represent only a subset of the plans available and may suit travelers who need a large but not unlimited data allowance. Choosing a fixed data plan can be more cost‑effective for most users, except for those who require very high data consumption beyond the fixed limits.

Spark Roam does not provide a Guernsey eSIM that includes a phone number or SMS capability; the available plans are data‑only. Travelers can still communicate using data‑based services such as WhatsApp, Telegram, or iMessage, which do not require an SMS‑capable number.

Spark Roam offers 4 single‑country plans that cover only Guernsey and 8 multi‑country plans that include Guernsey among other destinations. The plans run from about $1.33 to $45.62, with data caps ranging from 1 GB to 50 GB and validity periods between 7 and 180 days.
