ZenSim eSIM Data Plans for Ireland

ZenSim does not provide a truly unlimited data eSIM for Ireland. Its Ireland Unlimited STANDARD plans advertise “Unlimited” in the name but actually allow 3 GB of high‑speed data per day; after that the speed is reduced.

Travelers who need more data can choose one of the fixed‑data plans, such as the Ireland 20 GB - 10 Days package for $26, the Ireland 20 GB - 30 Days package for $29, or the Ireland 10 GB - 10 Days package for $18. These fixed‑data options give larger allowances and can be more cost‑effective for heavy data users.

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.
