Alodata does not provide a truly unlimited high‑speed data plan for Iceland. The plans that are labeled “Unlimited” give 1 GB (or 1 GB per day for multi‑day options) of full‑speed 4G/5G data before the speed is throttled to 1280 kbps. In other words, the name reflects the idea of an unlimited‑named plan but the data is capped and the connection slows after the cap is reached.
Travellers who need more data can choose one of the fixed‑cap plans that alodata offers. For example, the eSIM 100 GB for 30 days in Iceland costs $90 USD, and the eSIM 100 GB for 90 days in Europe + USA is available for $230 USD. These plans give a large amount of high‑speed data at a fixed price and are more cost‑effective for heavy data users than the capped “Unlimited” options.
