Comet SIM eSIM Data Plans for Luxembourg

Comet SIM does not provide an unlimited data eSIM for Luxembourg. The available eSIMs for Luxembourg are fixed‑data plans with set capacities and a 30‑day validity. For example, the Luxembourg eSIM — 20GB / 30 days delivers 20 GB of high‑speed data for 30 days, and the Luxembourg eSIM — 10GB / 30 days offers 10 GB for the same duration. These fixed plans may be more economical than purchasing many small pay‑as‑you‑go credits, especially for travelers who expect to use only a moderate amount of data.

Comet SIM does not offer a Luxembourg eSIM with a local phone number or SMS capability. Only data‑only eSIM plans are available for that destination. Travelers who need voice or text can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Luxembourg before purchasing.

Comet SIM has five single‑country eSIM plans that cover Luxembourg only, and ten multi‑country plans that include Luxembourg among other destinations. The single‑country plans start at about $3.90 for 1 GB and go up to $119.90 for 20 GB, with validity periods ranging from a week to a month. The multi‑country catalog offers a similar price range, spanning from the low‑end $3.90 for minimal data to the upper end near $120 for larger data allowances, with validity periods also between seven and thirty days. Both categories provide the usual fixed‑data‑amount plans (where a set amount of data is delivered for the entire validity) and the daily‑cap options (where a maximum daily data limit applies, allowing the balance to be used more flexibly over the period).
