Yes, several eSIM providers offer unlimited data plans that cover Guernsey. The available options come from abesteSIM, Truely, Roamify, Yoho Mobile, and esimzon.

Pricing for unlimited plans varies widely, with the lowest starting around $4.46 and the highest going up to about $449.07, while most plans fall between roughly $5.52 and $180.00 depending on the provider and validity period.
In Guernsey, the primary Mobile Network Operators (MNOs) are:
Sure (Guernsey) Limited: "The largest telecoms operator in the Channel Islands, providing mobile, fixed-line, and broadband services."
JT (Guernsey) Ltd: "Offers a range of telecom services, including mobile, broadband, and fixed-line connectivity."
Guernsey Airtel Ltd (Airtel-Vodafone): "Provides mobile services to both residents and visitors."
In addition to these MNOs, Guernsey has Mobile Virtual Network Operators (MVNOs) that offer mobile services by leasing access from major carriers. For example, the Channel Islands Co-operative Society has announced plans to launch "Coop Mobile," an MVNO utilizing Sure's network infrastructure. However, most travel eSIMs rely on MNO infrastructure, not MVNOs.
Travel eSIM plans that include a phone number and SMS are available for Guernsey from Roamify, SimOptions and MoreMins eSIM. These plans provide inbound and outbound voice and SMS and come in various data sizes from 1GB to 100GB. The phone numbers use international dialing codes: Roamify offers plans with +33, SimOptions uses +33, and MoreMins eSIM supplies a +44 number, while some Roamify Global Premium plans use +1. All of these numbers are foreign to Guernsey, so they are not local Guernsey numbers. Prices start around $15 and can be bought for validity periods ranging from 7 days to 365 days.
