aloSIM eSIM Data Plans for Guernsey

aloSIM does not provide an unlimited data eSIM for Guernsey. All available plans for the island have fixed data caps, the largest being 20 GB for a 30‑day validity period, priced at $62 USD. For travelers who need more data, other fixed options exist, such as the 10 GB plan for $30 USD or the 5 GB plan for $17 USD, all offering 5G connectivity within Guernsey. Choosing a fixed‑data plan can be more cost‑effective unless the user consumes a very high volume of data, in which case an unlimited plan would be necessary.

aloSIM does not offer any plan for Guernsey that includes a phone number or SMS capability. The provider only supplies data‑only eSIMs in that market.

Travelers can still make and receive calls and send messages using VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and do not require a local phone number or SMS service.

aloSIM offers five single‑country data plans for Guernsey and six multi‑country plans that include Guernsey. The available packages span a price range from about $5 to $62 USD and provide data caps between 1 GB and 20 GB, with validity periods from 7 to 30 days.
