ZenSim eSIM Data Plans for Guernsey

ZenSim does not provide a truly unlimited data eSIM for Guernsey. All plans that carry an “Unlimited” label actually offer a fixed amount of high‑speed data, after which the speed is throttled. For example, the Guernsey Unlimited STANDARD plans deliver 3 GB per day for 10 or 30 days, and the same applies to the Europe+ Unlimited STANDARD plans that also cover Guernsey.

If a user needs more data, ZenSim offers large fixed‑data alternatives such as 20 GB for 10 days or 20 GB for 30 days, both of which include tethering. These plans can be more economical for regular travelers, although very heavy data users may still find the capped “unlimited” plans preferable.

ZenSim does not provide Guernsey eSIM plans that include a phone number or SMS capability. The provider offers only data‑only eSIM plans for Guernsey. Travelers who need voice or text services can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages.

ZenSim currently lists 8 single‑country data plans and 8 multi‑country data plans that cover Guernsey. The available plans range in price from about $13 to $115 and include data caps from 3 GB up to 20 GB for a validity period of 10 to 30 days. Some plans use a fixed data allowance, while others deliver a daily data cap, providing different options for how data can be consumed during the validity window.
