MTX Connect does not provide an unlimited data eSIM plan for Luxembourg. The available options for travelers in Luxembourg are fixed data plans, such as the 10GB Luxembourg plan, the 10GB Luxembourg Unthrottled plan, and the 10GB LOCAL plan, each with a 30‑day validity period. These plans offer a set amount of data and can be more cost‑effective for most users, unless a traveler requires a very high data volume that would exceed the fixed allowance.
