eSimfly eSIM Data Plans for Guernsey

eSimfly does not provide a truly unlimited data eSIM for Guernsey. The available plans have fixed data caps. For example, the Bouygues Telecom 120 GB plan gives 120GB of high‑speed data for 30 days and costs $42.47 USD. Another option is the Global 100 GB 31 Days plan, which offers 100GB for 31 days at $68.07 USD. Fixed data plans can be cost‑effective unless you are an extremely heavy data consumer.

eSimfly offers several Guernsey eSIM plans that include a phone number and SMS. Prices range from $22.69 USD for the 20 GB 15‑day bundle to $42.47 USD for the 120 GB 30‑day bundle, and validity periods span 15 days for the smallest plan and 30 days for all other options.

All plans carry an international dialing code – Bouygues Telecom plans use +33 and O2 International plans use +44 – and each allows inbound and outbound voice calls as well as inbound and outbound SMS. The numbers are issued by the provider rather than being local Guernsey numbers, so travelers should confirm the exact capabilities they need directly with eSimfly.

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.
