abesteSIM eSIM Data Plans for Guernsey

abesteSIM does not provide a truly unlimited data eSIM plan for Guernsey. The only plan that uses the word “Unlimited” in its name—eSIM Europe (49 Destinations) – 1 Day / Unlimited—converts to a fixed allowance of 1GB per day and reduces speed to 5000kbps after that limit is reached. All other available eSIMs for Guernsey have a set data cap and a reduced speed of 128kbps once the cap is met.

If a visitor requires more data, abesteSIM offers high‑capacity fixed plans such as the eSIM Guernsey – 30 Days / Total 30GB for $23.79 USD or the eSIM Guernsey – 30 Days / Total 20GB for $17.21 USD. These plans provide a larger amount of high‑speed data before throttling, which may be more economical for most users unless an extremely heavy data consumer needs an unlimited‑style experience.

abesteSIM does not offer a Guernsey eSIM that includes a local phone number or SMS capability. The provider sells only data‑only eSIM plans for Guernsey, so users cannot receive or make traditional cellular voice calls or text messages. For communication, users can rely on internet‑based messaging and voice apps such as WhatsApp, Telegram, and iMessage, which work over the data connection the eSIM supplies.

abesteSIM provides 40 single‑country plans and 55 multi‑country plans that include coverage of Guernsey. The plans come in two main types: fixed data caps ranging from 500 MB to 30 GB over validity periods of 1 to 60 days, and daily data cap plans that allow a set amount of data each day within the same validity window. Prices span from $1.11 to $64.66 USD, and many plans offer optional tethering with reduced speeds of 128 kbit/s or 5000 kbit/s where applicable.
