nextSIM eSIM Data Plans for Guernsey

nextSIM does not provide a true unlimited‑data eSIM for Guernsey. All plans that contain the word “Unlimited” in their name actually include a defined data cap, such as 1GB or 2GB per day, and specify a reduced speed (512kbps or 2000kbps) once that cap is reached. For travelers who need high‑speed data without a hard daily limit, nextSIM offers fixed‑data alternatives. One example is the eSIM Guernsey 100GB 30days Standard plan, priced at $156.03 USD, which delivers 100GB of high‑speed data for the full 30‑day validity. Another option is the eSIM Guernsey 50GB 30days Standard plan at $91.54 USD, providing 50GB of unrestricted high‑speed data. These fixed‑data plans can be more cost‑effective for users who consume a large amount of data over their stay.

nextSIM does not provide a Guernsey eSIM that includes a phone number or SMS capability. The only Guernsey eSIM plans offered by nextSIM are data‑only plans.

Travelers who need voice or messaging services can use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection provided by the eSIM.

nextSIM offers 27 single‑country data plans that include Guernsey, plus 6 multi‑country plans that cover Guernsey along with other destinations. The plans are priced between US$3.41 and US$264.92, with data caps ranging from 1 GB to 100 GB. Within the catalogue there are 12 daily‑data‑cap plans that grant a set amount of data each day, and 21 fixed‑data‑cap plans that provide a lump‑sum amount of data for the entire validity period.
