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 eSIMs that include a phone number with full inbound and outbound voice call and SMS support are available for Guernsey. Providers such as Roamify, Airhub, Orange Travel, Stixrs, and RedEx eSIM offer dedicated Guernsey plans. These plans deliver a local Guernsey‑dialed number (for example, Airhub, Stixrs and RedEx eSIM use a +44 phone number) or a French‑dialed number (Roamify and Orange Travel use +33). All listed packages include both inbound and outbound voice and SMS capabilities.

The plans vary in data allowance and price. Small‑data options start around $15 for a 15‑GB package, while larger bundles can cost around $50 for a 100‑GB package and above. Some plans offer 30‑day validity, others 60 days, and prices generally increase with data volume. When choosing a provider, decide whether a local +44 number is preferable or whether a foreign +33 number will suffice; both will work for calling and texting while you are in Guernsey.
