nextSIM does not provide an unlimited high‑speed data eSIM plan for Ireland. All of its Ireland‑specific offerings have a fixed data cap—ranging from 1GB up to 100GB per 30‑day period—and the “Unlimited” label in the plan name only indicates that the high‑speed part of the package is not capped, after which the speed is reduced to 512 kbps or 2000 kbps.
Travellers wishing for larger data allowances can choose from the fixed plans that are available, such as the 100GB 30‑day Ireland package, or the 50GB 30‑day Ireland package. These fixed‑data plans provide high‑speed 3G/4G/5G coverage throughout Ireland without a data cap, offering a cost‑effective alternative for moderate to heavy data usage.
