YonoSIM eSIM Data Plans for Guernsey

YonoSIM does not provide an unlimited‑data eSIM option for Guernsey. Travelers who need a larger data allowance can choose from the fixed‑data plans listed on the platform. Examples include the 20GB 30‑day and 20GB 90‑day packages, both priced at $63.99 USD, and the 10GB 30‑day option at $36.99 USD. Selecting a fixed plan can be more cost effective unless the user is an extremely heavy data consumer.

YonoSIM does not provide a Guernsey eSIM that includes a local phone number or SMS capability. The provider offers only data‑only plans for this destination, so customers will need to rely on data‑connected VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages. Travelers should verify that these services work reliably in Guernsey, as some destinations may limit or block access to specific apps.

YonoSIM provides a total of 15 data offerings that cover Guernsey, including 5 single‑country plans designed solely for use on the island and 10 multi‑country plans that include Guernsey in a broader geographic package. The available choices span a wide spectrum, with prices ranging from roughly $2.40 to $63.99 and data caps between 500 MB and 20 GB. Some of the plans offer a fixed data amount while others are available as daily data capping options, and a few may apply a reduced speed limit of 384 kbit/s.
