ZenSim eSIM Data Plans for Guernsey

ZenSim does not provide a truly unlimited high‑speed data eSIM for travelers to Guernsey. The plans that carry the “Unlimited” label actually offer a fixed daily allowance of 3 GB per day, after which the data speed is throttled; this does not allow continuous high‑speed usage without a cap.

Customers who need more data can choose one of ZenSim’s fixed‑data plans. For example, a 40 GB plan with a validity of 30 days costs $51.00 USD, and a 20 GB plan valid for 10 days is priced at $26.00 USD. These alternatives give a larger quantity of high‑speed data before any reduction occurs and often prove more economical for frequent data users.

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 offers a mix of single‑country and multi‑country eSIM plans that cover Guernsey. In total the provider lists eight single‑country plans and nine multi‑country plans that include Guernsey in their coverage. The plans vary in price from around $13 to $115, with data caps ranging from 3 GB up to 40 GB and validity periods between 10 and 30 days. Some of the plans are fixed data capping the amount of data you can use (e.g., 3 GB or 15 GB caps), while others allow a daily data limit that resets each day. Tethering is also permitted on several of those plans.
