ZenSim eSIM Data Plans for Guernsey

ZenSim does not provide a true unlimited high‑speed data eSIM for Guernsey. All of the plans listed for this destination have a fixed data cap; for example the plans labeled “Unlimited” allow 3 GB of high‑speed data per day, after which the speed is reduced.

Travelers who need a substantial amount of data can choose one of ZenSim’s fixed‑data options instead. A 20 GB plan lasts 10 days and costs $42.00 USD, while a 20 GB plan lasting 30 days costs $48.00 USD. Other fixed plans include 10 GB for 10 days ($27.00 USD) and 5 GB for 10 days ($17.00 USD). These options may be more cost‑effective for most users, unless one requires continuous high‑speed data beyond the capped limits.

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.
