ZenSim eSIM Data Plans for Ireland

ZenSim does not provide a truly unlimited high‑speed data eSIM for Ireland. The plans that carry “Unlimited” in their name grant only 3 GB per day for the stated validity period; after the daily quota is reached the speed is throttled, so the data is not unrestricted.

If you need a larger data allocation, ZenSim offers fixed‑data options as alternatives. For example, the 20 GB plans are available for 10 or 30 days, and a 10 GB plan can be purchased for 10 days. These fixed plans give you a set amount of high‑speed data, which can be more cost‑effective unless you require an unbounded data supply.

ZenSim does not provide eSIM plans for Ireland that include a phone number or SMS capability. Only data‑only eSIMs are offered by the provider for this destination.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, which work without a local phone number or SMS service.

ZenSim offers a total of 16 distinct data plans for Ireland, split evenly between single‑country and multi‑country options: eight single‑country plans and eight multi‑country plans. Prices range from about $13 to $57, while data caps vary from roughly 3 GB to 20 GB for a validity of 10 to 30 days. Among these plans, four use a daily data cap—allowing the user to limit data usage on a day‑by‑day basis—whereas the remaining twelve provide a fixed amount of data that can be used throughout the plan’s validity. Some of the plans also allow tethering.
