No, nextSIM does not provide a truly unlimited‑data eSIM for travelers in Ireland. The plans that contain “Unlimited” in their name actually give a fixed high‑speed allowance—most give 1 GB per day or 2 GB per day for the validity period, and once that allowance is used the connection is throttled to a reduced speed (512 kbps for the 1 GB plans and 2000 kbps for the 2 GB plans).
Travelers who need a larger, non‑limited data pool can select one of nextSIM’s fixed‑data plans, such as the 100 GB 30‑day plan priced at $60.62 USD or the 50 GB 30‑day plan priced at $31.30 USD. These plans provide the full data amount at full speed without any subsequent throttling, which can be more economical for heavy data users compared to the di‑day “Unlimited” offerings.
