NextSIM does not offer a truly unlimited data eSIM for Ireland. All plans marked with “Unlimited” in the name contain a fixed data allowance that is shared across the validity period, after which the connection speed is reduced. For example, the eSIM Unlimited Standard 10 Days Ireland plan provides 1 GB per day (a total of 10 GB) and reduces speed to 512 kbps once the daily limit is reached, while the eSIM Unlimited Plus 10 Days Ireland plan gives 2 GB per day with a reduced speed of 2000 kbps after the limit is used.
Travelers who prefer a consistent data experience can choose a fixed high‑data plan. Two illustrative options available for Ireland are the eSIM GLOBAL 50GB 365Days Economy bundle, which gives 50 GB over a full year, and the eSIM EUROPE 30GB 30Days Premium offering 30 GB for 30 days. These plans provide more predictable usage and can be more cost‑effective for moderate to high data consumption compared with the capped “Unlimited” names.
