nextSIM eSIM Data Plans for Guernsey

nextSIM does not provide a truly unlimited data eSIM for Guernsey. Plans that carry “Unlimited” in the name actually offer a fixed amount of high‑speed data, such as 1 GB or 2 GB per day (or for the total validity period). Once that amount is used, the speed is reduced to 512 kbps or 2000 kbps, respectively.

Travelers who need more data can choose from fixed‑data plans that offer larger caps. For example, nextSIM lists a 100 GB 30 days Standard plan for $183.49 USD, a 50 GB 30 days Standard plan for $107.64 USD, and a 20 GB 30 days Standard plan for $48.04 USD. These options are typically more cost‑effective for users who consume a lot of data.

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 and 6 multi‑country plans that include coverage for Guernsey, giving travelers a total of 33 options. The available plans range in price from $3.41 to $264.56 and provide data limits between 1 GB and 100 GB. Some plans deliver a fixed data amount (21 plans) while others cap data usage on a daily basis (12 plans), giving users choice between a set data allotment and a daily cap structure.
