4S eSIM eSIM Data Plans for Ireland

4S eSIM does not provide a true unlimited data plan for Ireland.
All of its offerings for that country are fixed data plans with a hard cap, such as the 3GB, 5GB, 10GB, 20GB, 30GB, and 50GB plans that are valid for 1 to 30 days. Plans that carry “Unlimited” in the name give a set data allowance and, once that amount is reached, the speed is throttled to 1000 kbps. Choosing a fixed data plan can be more cost‑effective for many travelers, especially if they need a predictable amount of high‑speed data during their stay.

4S eSIM does not offer any eSIM plans with a local phone number or SMS capability for Ireland. Only data‑only plans are available from this provider.

While you cannot receive voice calls or SMS through the eSIM, you may use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. It is advisable to verify that these services are accessible in Ireland before purchasing, as some destinations may block or restrict certain apps.

4S eSIM offers 54 single‑country data plans that provide data exclusively for Ireland, along with 108 multi‑country plans that include Ireland as part of a broader travel coverage. The available packages span a price range from $1.42 to $195.83 and a data cap range from 714 MB to 50 GB. Single‑country plans give you data only within Ireland, while multi‑country plans grant the same data allowance across multiple destinations in addition to Ireland.
