abesteSIM eSIM Data Plans for Guernsey

abesteSIM does not provide a truly unlimited data eSIM plan for Guernsey. The only plan that carries “Unlimited” in its name—eSIM Europe (49 Destinations) – 1 Day / Unlimited—actually limits usage to 1 GB per day and reduces speed to 5000 kbps once that limit is reached. Travelers looking for high‑capacity options can choose from fixed‑data plans, such as the eSIM Guernsey – 30 Days / Total 30 GB plan that offers 30 GB of high‑speed data for 30 days, or the eSIM Europe (49 Destinations) – 30 Days / Total 20 GB plan with 20 GB of data available for the same period. These plans keep 5G speeds until the data allowance is consumed, after which the speed drops to the specified reduced rate. For very heavy data users, a fixed‑data plan can be more cost effective than the daily‑limited “unlimited” option.

abesteSIM does not provide an eSIM for Guernsey that includes a phone number or SMS capability. The provider only offers data‑only plans for that destination. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging, but they should confirm that these services are accessible in Guernsey before purchasing.

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.
