eSimfly eSIM Data Plans for Guernsey

eSimfly does not provide a true unlimited‑data eSIM for Guernsey. All of its Guernsey plans that are labeled “Unlimited” are capped at a maximum of 1 GB per day, so once that daily threshold is reached the plan’s speed will be throttled. For travelers who need more data, eSimfly offers fixed‑data options such as the 100 GB 30‑day plan for $228.56 USD or the 50 GB 30‑day plan for $134.08 USD. A fixed‑data plan can be more cost‑effective for most users unless they require truly unlimited high‑speed data.

eSimfly does not provide any Guernsey eSIM plans that include a phone number or SMS capability. All eSimfly offers for Guernsey are data‑only plans. Travelers can still use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages without requiring a local phone number or SMS service.

eSimfly provides a range of plans that include Guernsey. Among its options, 16 single‑country plans are available, while 12 multi‑country plans cover the island. These plans span a price range from about $5 to $229 and offer data caps between 1 GB and 100 GB, with validity periods that can last from a single day up to a full year. Flow‑based options are also present, with 6 plans featuring daily data caps and 22 offering fixed data amounts. Only a subset of the 16 single‑country plans and 12 multi‑country plans are relevant to Guernsey; the exact split depends on the specific provider listing in eSIMDB.
