ZenSim eSIM Data Plans for Iceland

ZenSim does not offer a true unlimited data eSIM for Iceland; the plans with “Unlimited” in their titles actually limit usage to 3 GB per day, and speeds drop to 1000 kbps after that point.

Travelers who need more data can choose from ZenSim’s fixed data plans, such as the Iceland 40 GB‑30 days plan for $45 USD or the Iceland 20 GB‑15 days plan for $23 USD, which provide larger data allowances without throttling until the allocated data is exhausted.

ZenSim does not offer an Iceland eSIM that includes a phone number or SMS capabilities. The provider’s Iceland plans are data‑only.

Travelers who need voice or messaging can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, although some destinations may block or restrict access to specific apps or VoIP services, so it is advisable to confirm their availability in Iceland before purchasing a plan.

ZenSim offers 13 single‑country data plans and 18 multi‑country plans that include Iceland. Prices range from roughly $5 to $119, and data caps vary from 1 GB to 40 GB. The portfolio includes both fixed‑data plans, which provide a set amount of data for the entire validity period, and daily‑cap plans, which limit the amount of data that can be used each day. Overall ZenSim offers 6 daily‑cap options and 25 fixed‑data options.
