What are the major mobile networks available for a travel eSIM in Guernsey?

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.

Can I get a travel eSIM with a phone number and SMS for Guernsey?

Travel eSIM plans that include a phone number and SMS are available for Guernsey. Providers such as JamboSim, ESIM.DOG, Roamify, Airhub, eSimfly, and Orange Travel offer these plans, with validity periods from 7 days up to 180 days and data amounts ranging from 1GB to 100GB. Prices for the earliest plans start around $11.99 USD, while larger data packages are priced between $15.00 USD and $70.00 USD.

The telephone numbers on these plans use a range of dialing codes. Plans that list a +44 dialing code give the holder a local Guernsey phone number, which is useful for local voice calls and SMS. Plans that use +33 (France) or +1 (United States/Canada) provide foreign numbers; while they still support inbound and outbound voice and SMS, the number will appear as a France or US/Canada number when displayed locally. All plans support both voice and SMS, and most also allow data tethering. Travelers who prefer a purely local number should select a plan with the +44 dialing code.
