eSIM4Travel does not provide a truly unlimited data eSIM for Luxembourg.
The plans called “Unlimited‑…Luxembourg” give 3 GB of high‑speed data per day and throttle the connection to 1000 kbps once that daily limit is reached, so the high‑speed data is still capped.
Travelers can instead choose fixed data plans that are specifically designated for Luxembourg. Examples include a 50 GB plan for 30 days or a 20 GB plan for 30 days, both of which are unthrottled and offer a defined amount of high‑speed data over a set validity period. These fixed‑data alternatives may be more cost effective for those who require a predictable data allowance.
