MobileSIM eSIM Data Plans for Guernsey

MobileSIM does not provide an unlimited data eSIM for travelers in Guernsey. All of the plans it offers for the island have a fixed data allowance, ranging from 5GB to 60GB, and each plan comes with a specified validity period.

Travelers who need large data volumes can choose one of MobileSIM’s fixed‑data plans. For example, the 60 GB plan is valid for 125 days and costs $165 USD, while a 20 GB plan is available for 30 days at $66 USD. These fixed‑data options can be more cost‑effective for most users unless one expects to use data at a rate that would exceed the plan’s cap.

MobileSIM does not provide a Guernsey eSIM that includes a local phone number or SMS capability. Only data‑only plans are available for Guernsey.

Travelers who need to make voice calls or send messages can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict certain VoIP services, so it is advisable to confirm that the apps you rely on are accessible in Guernsey before purchasing a MobileSIM plan.

MobileSIM offers ten multi‑country data plans that include coverage in Guernsey, with no single‑country plans available. The plans span a price range from $2.30 to $165.00 and offer data caps between 200 MB and 60 GB, giving users a broad selection of options from low‑cost, minimal‑data packages to high‑capacity plans suitable for heavier usage.
