eSIMCard does not provide a truly unlimited high‑speed data plan for Ireland. All of its Ireland‑specific plans list a high‑speed data cap (for example, 50 GB for 30 days, 35 GB for 30 days, or 10 GB for 10 days) and some “Unlimited” titles actually grant a limited amount of high‑speed data before the connection is throttled to a lower speed (for example, 1 GB for 1 day with a reduced speed of 512 kbps or 2000 kbps after the cap).
Fixed‑data options are available, such as the 50 GB plan for 30 days or the 35 GB plan for 30 days. These plans give a substantial high‑speed allowance without triggering throttling and can be more cost‑effective for users who need consistent access rather than an unlimited‑data experience.
