Simsima eSIM Data Plans for Iceland

Simsima does not provide a truly unlimited high‑speed data plan for Iceland. The plans marketed as “Unlimited – 7 days / 10 days / 30 days” actually give 3 GB per day and, once that daily allowance is used, the speed drops to 1000 kbps. These are fixed‑data plans that are identified with the word “Unlimited” in their names but are not unlimited in the sense of unlimited high‑speed data.

Travelers who need a larger amount of data without the speed reduction can choose a fixed‑data plan such as the 100GB‑180 days plan, the 50GB‑30 days plan, or the 20GB‑30 days plan. These plans offer set data allowances at a fixed price and can be a more cost‑effective option unless a user is a very heavy data consumer who would truly benefit from unlimited data.

No, Simsima does not offer an Iceland eSIM with a phone number or SMS capability. Travelers using a Simsima eSIM in Iceland can access only data; they can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages, but the availability of these services is not guaranteed in all situations, so users should confirm that the apps they need work in Iceland before purchasing.

Simsima provides 11 single‑country plans and 19 multi‑country plans for Iceland, covering a wide spectrum of options. The plans vary from as little as 1 GB of data available for a handful of days to several hundred gigabytes of data for up to 180 days, with prices ranging from about $3.91 to $172.36. Some of the offerings are fixed‑data plans with a set amount of data that does not change during the validity period, while others are daily‑data cap plans where the amount of data available is refreshed each day.
