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 plans that cover Ireland. The price points span from about $2.34 for a 200 MB package to roughly $99.00 for a 50 GB offering, while validity ranges from 3 to 60 days. Some packages come with a fixed data cap that is usable for the entire period, whereas other options impose a daily data limit before the allowance resets, allowing users to choose the schedule that best matches their travel needs.
