abesteSIM eSIM Data Plans for Guernsey

abesteSIM provides unlimited data eSIM plans for Guernsey with validity periods ranging from 1 day to 30 days. The prices start at $3.35 USD for 1 day and increase to $66.83 USD for a 30‑day plan, with intermediate options at $8.53 USD for 3 days, $13.34 USD for 5 days, $18.49 USD for 7 days, $26.26 USD for 10 days, $39.17 USD for 15 days, and $52.07 USD for 20 days. All unlimited plans support 5G connectivity, allow tethering, and list a maximum speed of 5000kbps, though the speed may be throttled after heavy usage as part of the fair usage policy.

Because speeds may be reduced after heavy usage, users who are concerned about potential throttling should contact abesteSIM directly to confirm the presence of a fair usage policy and to learn how much data remains at normal speed before throttling occurs.

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 lists 47 single‑country plans that include Guernsey. In addition, Guernsey is covered by 62 multi‑country plans that combine several destinations into one tariff. The available plans span a price range from $1.00 to $68.79 USD and data caps from 500 MB up to unlimited. Some of the plans are fixed data‑cap products, giving a set amount of data for the validity period, while others impose a daily data out‑per‑day limit before any throttling applies.
