eSIMCard’s plans that carry “Unlimited” in the name are not truly unlimited. Each of those offerings includes a data cap of 1GB or 2GB per day; once the cap is reached the speed is reduced to 512kbps or 2000kbps. The high‑speed data allowance is therefore limited, and the plan is only “unlimited” after throttling.
If a traveler needs a larger amount of high‑speed data without throttling, eSIMCard provides fixed‑data packages for Ireland. Examples include the 50GB Data & Unlimited Minutes plan valid for 30 days and priced at $31.39 USD, the 35GB Data & Unlimited Minutes plan also for 30 days, and the 100GB eSIM Data plan valid for 90 days. These options offer substantial data volumes without the speed reduction that applies to the Unlimited‑named plans.
