Yes, esimzon offers unlimited‑data eSIM plans that include Iceland. The provider’s “Europe Unlimited” plans—available for 1, 3, 5, 7, 15, and 30 days—carry an unlimited data allowance and are valid for the specified number of days. Prices for these plans range from $4.99 for a 1‑day service to $62.99 for a 30‑day service. Each plan lists a maximum speed of 10 Mbps, with a note that speeds may be throttled after heavy usage as part of a fair usage policy. If a traveler wants to confirm how much data remains at full speed or whether speed reductions will occur, they can contact esimzon for clarification.
