eSIM4Travel does not provide a truly unlimited data eSIM for Ireland. The plans that carry the word “Unlimited” in their name actually offer 3GB of high‑speed data per day and reduce the speed to 1000 kbps once that daily limit is reached, so the data is not unlimited.
Travelers who need a larger, unthrottled allowance can choose fixed data plans such as the 50GB/30Days or 20GB/30Days options, both of which are unthrottled and valid for 30 days on 5G networks in Ireland. These fixed plans may be more cost‑effective for most users unless they require very heavy data usage.
