MobileSIM eSIM Data Plans for Ireland

MobileSIM does not provide a truly unlimited high‑speed data plan for Ireland. All plans that carry the “Unlimited” name limit high‑speed usage to 3 GB per day; once this quota is reached, speed is throttled to 1000 kbps. These plans are still marketed as “unlimited” because only the highest speeds are capped, not the total data amount.

If a traveler prefers a fixed‑data approach, MobileSIM offers several alternatives for Ireland, such as a 20 GB plan for 30 days at $28.00 USD and a 50 GB plan for 30 days at $42.00 USD. Fixed‑data plans can be more cost‑effective for users who stay within the data allowance, unless the user expects to consume an exceptionally large amount of data during the stay.

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 provides 13 single‑country data plans and 22 multi‑country data plans for users travelling to Ireland. The available plans range in price from roughly $1.00 to $99.00, with data caps spanning from 200 MB up to 50 GB. Within the single and multi‑country offerings, 12 plans apply a daily data cap while 23 feature a fixed data quantity, and a small subset of plans includes a reduced speed threshold of 1 Gbps.
