eSimfly eSIM Data Plans for Guernsey

eSimfly does not currently offer a truly unlimited data eSIM for Guernsey. The plans available for the destination are fixed data plans, each with a hard data cap and a 30‑day validity period. For example, the Bouygues Telecom 120GB plan gives 120GB of high‑speed data for 30 days and is priced at $42.47 USD, while the Orange World 100GB 30 Days plan offers 100GB for 30 days at $69.07 USD. These plans provide a set amount of data that must be used within the validity window; once the data cap is reached, the plan terminates and no further high‑speed data is available. The O2 Unlimited (International) plan listed in the catalogue has a 35GB data cap, so it is not truly unlimited. Travelers who anticipate very high data usage may find a larger fixed plan more cost‑effective than opting for pay‑as‑you‑go billing.

eSimfly supplies eSIMs for travel to Guernsey that include a phone number with full telephony functions. The plans range in price from $22.69 USD for a 20 GB package valid for 15 days to $42.47 USD for a 120 GB package valid for 30 days. Each plan provides a phone number with the dialing code +33 (French) or +44 (British); incoming and outgoing voice calls can be made and received, and incoming and outgoing SMS are also supported.

The dialed numbers are not local Guernsey numbers but partner numbers from France or the United Kingdom, so they will not show as a local Guernsey number. Users who require a specific type of call or SMS capability should confirm the exact details with eSimfly directly before purchase.

eSimfly offers 6 single‑country data plans that cover Guernsey, in addition to 36 multi‑country plans that include the island. The plans range in price from roughly $3.56 to $121.38 and provide data amounts between 1 GB and 200 GB, with validity periods spanning 5 to 365 days. Some of the plans allow tethering.
