MobileSIM eSIM Data Plans for Ireland

MobileSIM does not provide a truly unlimited high‑speed data eSIM for Ireland. All plans that bear “Unlimited” in their name deliver only 3 GB of high‑speed data per day and, once that limit is reached, the connection speed drops to 1000 kbps.

If unlimited use is required, travelers can choose one of MobileSIM’s fixed‑data options instead. For example, a 50 GB plan valid for 30 days or a 20 GB plan for 30 days are available and can be more cost‑effective for users who consume a lot of data. These fixed plans give consistent high‑speed access for the entire validity period.

MobileSIM does not provide an eSIM plan for Ireland that includes a phone number or SMS capability. Only data‑only eSIMs are available from the provider. Travelers can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging.

MobileSIM lists 11 single‑country data offers for Ireland and 17 multi‑country bundles that include Ireland.
Plan prices range between approximately $3 and $185, with data allowances from 500 MB up to 100 GB and validity periods from 3 to 365 days.
The catalog contains 5 daily data‑cap options—typically suited to short stays—and 23 fixed‑data options that provide a set amount of periods.
Some plans include a reduced speed option capped at 1000 Mbps.
