WonderConnect eSIM Data Plans for Guernsey

There are no unlimited data eSIM plans from WonderConnect for travel to Guernsey.
WonderConnect offers fixed‑data options instead, such as the Jersey plan with 20GB for 30 days that costs $38.99 USD, or the Global plan with 20GB for 30 days that costs $116.99 USD. Choosing a fixed data plan can provide a more cost‑effective solution for most travelers unless you are an extremely heavy data user.

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.
