abesteSIM eSIM Data Plans for Guernsey

abesteSIM provides several unlimited data eSIM plans that cover Guernsey, ranging in validity from 1 day to 30 days and priced between $4.46 USD for a 1‑day plan and $90.37 USD for a 30‑day plan. All unlimited plans offer 4G, LTE coverage and allow tethering, but speeds may be throttled; the maximum speed is capped at 5000 kbps.

Because the plans are subject to a Fair Usage Policy, speeds can be reduced after heavy usage. Travelers who are concerned about potential speed restrictions should contact abesteSIM directly to confirm whether the FUP applies and to learn the typical amount of data available at normal speed.

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 offers 47 single‑country data plans and 62 multi‑country data plans that include Guernsey. The plans come in two main formats: fixed data‑cap options, which provide a set amount of data for the full validity period, and daily‑cap options, which allow a set amount each day. Prices range from about $1.33 to $93.03 USD, while data caps span from 500 MB to unlimited.
