TailSim eSIM Data Plans for Iceland

TailSim does not provide a true unlimited‑data eSIM for Iceland. All of its Iceland‑specific offerings are fixed data plans, the largest of which is a 50 GB bundle valid for 30 days at $68.99 USD. Other large‑data options include a 20 GB plan for 30 days and a 10 GB plan for the same period. Plans that include “Unlimited” in the name actually grant 3 GB per day, after which the speed is reduced (512 kbps in Iceland), so they are not truly unlimited. If a user needs more data, selecting one of the fixed‑data bundles is typically more cost‑effective than relying on the throttled “Unlimited” plans.

TailSim does not provide a phone number or SMS capability for its eSIM plans in Iceland. The provider offers only data‑only eSIMs for that destination.

Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging, but some destinations might block or restrict these services. It is advisable to confirm that the apps you rely on are accessible in Iceland before purchasing.

TailSim offers 14 single‑country plans and 14 multi‑country plans that include Iceland. The plans are priced between $3.99 and $85.50 and provide data caps ranging from 1 GB to 50 GB, with validity periods from 3 to 30 days. Some plans use a daily data cap, limiting the amount of data that can be used each day, while others use a fixed data cap that allows the full amount to be used over the entire validity period. Tethering is allowed on many plans, and a reduced speed of 1000 kbps may apply on certain plans.
