4S eSIM eSIM Data Plans for Ireland

4S eSIM does not provide a true unlimited high‑speed data plan for Ireland. All plans that carry “Unlimited” in the name have a set data cap and, once that cap is reached, the speed drops to 1000kbps. For example, the Ireland 20GB Unlimited – 5 days plan delivers 4GB of high‑speed data per day before throttling, and the Ireland 50GB Unlimited – 5 days plan gives 10GB each day before the same speed reduction applies.

Customers who need large, unthrottled data amounts can opt for 4S eSIM’s fixed data plans instead. These plans offer a clear data allowance—such as Ireland 50GB – 5 days or Ireland 30GB – 15 days—with no speed curtailment after a certain point, which can be more economical for heavy data users.

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.
