nextSIM does not provide an unlimited‑data eSIM option for Ireland. All of the plans listed in the provider’s catalogue have a defined data cap; for the ones titled “Unlimited” the high‑speed allowance is limited to 1 GB (per day for multi‑day packages) and once that limit is reached, the speed is reduced to either 512 kbps or 2 000 kbps depending on the specific package.
If you need a larger data supply, nextSIM offers fixed‑data plans such as the 100 GB 30‑day Ireland plan priced at $58.55 USD and the 50 GB 30‑day Ireland plan priced at $30.23 USD. These plans provide the full 5 G (or 4 G, 3 G) speed for the entire data allowance, which may be more cost‑effective for travelers looking for extensive usage without the speed throttling that comes after a capped amount.
