Everything you need to know about using eSIMs in Guernsey
More than two hundred travel eSIM providers and over five thousand prepaid data plans are available for use in Guernsey, offering a wide variety of options that make it easy for travelers to find an eSIM that meets their needs.
Yes. There are unlimited data eSIM options that cover Guernsey. The providers that offer such plans are ESIM.DOG, Roamify and Orange Travel. These plans generally allow tethering and may have speed throttling after certain thresholds, with ESIM.DOG specifying a maximum speed of 384 kbps. Prices for the unlimited packages vary widely, starting around $2.18 and going up to roughly $74.99, so travelers can choose a plan that fits their budget while ensuring sufficient data for browsing, streaming and other online activities.
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 for Guernsey that include a phone number and SMS support are available from several providers. Providers such as JamboSim, ESIM.DOG, Earth Esim, Roamify, CocoRoam and LineCast offer contact numbers, SMS, and voice calls. Most of these plans use the dialing code +33, which is the code for France, so the phone number is not locally local to Guernsey. Only plans with the +44 code (e.g., RedEx eSIM, Earth Esim UK data plans) provide a UK‑style number that is closer to the local Guernsey area code, although Guernsey’s own code is listed as +44 in the dataset, not the +33 used by many providers.
Typical pricing for these plans starts around $11.99 USD for a 1‑GB, 7‑day data package with outbound voice and SMS, and ranges up to several dollars more for larger data caps or longer validity periods. All plans allow data usage and, in many cases, tethering or Wi‑Fi hotspot functionality. They also offer inbound and outbound calls and SMS, enabling travelers to maintain regular communication while visiting Guernsey.
