WonderConnect eSIM Data Plans for Guernsey

WonderConnect does not offer an unlimited data eSIM plan for Guernsey. All available plans have a fixed data cap, such as the Jersey 20GB plan that lasts 30 days and costs $44.99 USD, or the Jersey 10GB plan for $23.99 USD. These fixed data plans provide a clear amount of high‑speed data and can be more cost effective for most travelers, unless you need very high data usage.

WonderConnect does not offer a Guernsey eSIM plan that includes a phone number or SMS capability. Travelers who need a local number for voice or text messages will need to use alternatives.

If a data‑only plan is purchased, popular VoIP applications such as WhatsApp, Telegram, and iMessage can usually be used over the data connection to make calls and send messages. Some destinations may restrict access to certain apps or services, so it is wise to confirm that the required VoIP options are available in Guernsey before purchasing.

21 WonderConnect offers 15 multi‑country eSIM plans for Guernsey, none of which are dedicated single‑country offerings. The available plans vary widely in price, from $4.49 up to $134.99, and in data allowance, ranging from 1 GB to 20 GB. The plans are valid for between 7 and 30 days and include an option for tethering.
