eSimfly eSIM Data Plans for Guernsey

eSimfly does not provide a truly unlimited data eSIM for Guernsey. The plans labelled “Guernsey Unlimited” actually allow only 1GB of high‑speed data, with the name being a marketing convention rather than a data cap statement. After the 1GB limit is reached, the speed is throttled, although a specific reduced speed is not listed.

If a higher data allowance is required, eSimfly offers fixed‑data alternatives. For example, a 100GB 30‑day plan is priced at $228.56, a 50GB 30‑day plan at $134.08, and a 20GB 30‑day plan at $59.85. These plans provide a larger amount of high‑speed data and can be more cost‑effective for most travelers to Guernsey.

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 18 single‑country data plans and 12 multi‑country plans for Guernsey. The available offerings span prices from roughly $5.01 to $228.56 while data caps range from 1 GB up to 100 GB and validity periods extend from 1 day to a full year.
