nextSIM eSIM Data Plans for Iceland

nextSIM does not offer a truly unlimited data eSIM plan for Iceland. The plans that carry the “Unlimited” label actually provide a fixed amount of high‑speed data—typically 1GB or 2GB per validity period—and after that limit the speed to 512kbps or 2000kbps. For example, the eSIM Iceland Unlimited 1Days Standard plan offers 1GB with a reduced speed of 512kbps once the data cap is reached, while the eSIM Iceland Unlimited Plus 1Days Standard plan provides 2GB before throttling to 2000kbps. If a traveler needs more data without throttling, nextSIM also offers fixed‑data plans such as the 50GB 30Days Standard and the 100GB 30Days Standard plans. Choosing these higher‑cap plans can be more cost‑effective for heavy data usage compared to the capped “Unlimited” options.

nextSIM does not currently offer eSIM plans for Iceland that include a phone number or SMS capability. Only data‑only eSIMs are available from this provider. Travelers can still use VoIP apps such as WhatsApp, Telegram, and iMessage over the data connection for calls and messaging.

nextSIM provides a broad selection of plans that cover Iceland, including 35 single‑country options and 91 multi‑country options. The plans vary from a minimal $1.54 fee for a 1 GB data allowance to $1, 299.63 for a 100 GB plan, and validity periods range from a single day to an entire year. Plans are divided into daily‑data‑cap plans, where the data limit is reset each day (52 such plans), and fixed‑data‑cap plans, where a set amount of data is available for the full validity period (74 plans). This variety allows travelers to choose between a brief burst of connectivity or a longer‑term, predictable data allowance.
