nextSIM eSIM Data Plans for Guernsey

nextSIM does not offer a truly unlimited data eSIM for Guernsey. The plans labeled “Unlimited” give a fixed amount of high‑speed data—such as 1 GB per day or 2 GB per day—for the validity period, and once that cap is reached the speed is reduced to 512 kbps or 2000 kbps. If a traveler needs more data, nextSIM provides fixed‑data plans, for example an 100 GB 30 days plan for $161.79 USD or a 50 GB 30 days plan for $94.90 USD, which supply larger data allowances without a speed reduction. Choosing a fixed data plan may be more cost effective unless the user is an extremely heavy data consumer.

nextSIM does not offer any eSIM plan for Guernsey that includes a phone number or SMS capability. The only eSIM options available for the island are data‑only plans.

Because the eSIM does not provide voice or text services, travelers can still communicate by using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.

nextSIM offers 20 single‑country data plans that include Guernsey and one multi‑country plan covering Guernsey within a broader regional package. The single‑country plans vary from roughly $3.54 to $161.79 in price and 1 GB to 100 GB in data cap, with 10 daily‑cap plans and 11 fixed‑cap plans. The multi‑country plan falls within the same price range but typically provides a larger data allowance as part of a broader regional offer.
