ZenSim eSIM Data Plans for Guernsey

ZenSim does not provide a truly unlimited data eSIM for Guernsey. The plans that carry “Unlimited” in their name actually give 3GB of high‑speed data per day and then throttle the speed to 1000 kbps once that daily limit is reached, so the data is not unlimited.

Travelers who need a larger, fixed amount of data can choose from ZenSim’s fixed data plans for Guernsey, such as the 40GB plan valid for 30 days or the 20GB plan valid for 15 days. These plans offer a set amount of high‑speed data that must be used within the specified validity period, and they can be more cost‑effective for most users unless very heavy data consumption is expected.

ZenSim does not offer a Guernsey eSIM with a local phone number or SMS capability. Only data‑only eSIM plans are available for Guernsey. Travelers who need voice or text services can usually use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these apps are accessible in Guernsey before purchasing a plan.

ZenSim provides 12 single‑country plans and 18 multi‑country plans that cover Guernsey. The plans range in price from about $6 to $119 and offer data caps between 1 GB and 40 GB. Some plans use a fixed data amount, while others apply a daily data cap, giving customers flexibility depending on their usage patterns.
