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 Roamify, Earth Esim, LinkeSIM, SimOptions and MoreMins eSIM offer these plans. All of them support inbound and outbound voice and SMS. The majority use the +33 dialing code, meaning the phone number is from a foreign country. Two plans use +44 (provided by MoreMins eSIM), which shares the country code of Guernsey and therefore acts as a local number for the island. The remaining plans from Roamify that use the +1 dialing code provide US‑based numbers, which are also foreign to Guernsey.

Prices for these plans start around US$15 for a 15GB data package valid for 30 days and extend to about US$120 for a 500GB data package valid for 90 days, with a wide range of validity periods from 7 days up to 365 days. The data caps and validity can vary within that price range depending on the specific provider and plan selected.
