Ovosim does not supply a truly unlimited high‑speed eSIM for Ireland. The plans branded “Unlimited” give a fixed amount of high‑speed data that is capped at a stated data cap—and once that cap is reached the speed drops to 1 Mbps.
Travelers can choose fixed data plans that provide sizable allowances. For example, the EUconnect Unlimited 10 Days plan gives 66 GB of high‑speed data for 10 days before throttling, and the Europe Premium Unlimited 5 Days plan offers 6 GB of high‑speed data each day for five days with the same reduced speed after the daily limit is used. These options can be more economical for typical travelers, though very heavy data users may prefer a genuinely unlimited solution.
