eSimfly eSIM Data Plans for Luxembourg

eSimfly does not provide a genuinely unlimited high‑speed data eSIM for Luxembourg. All of its “Unlimited” plans give a fixed allowance of 3 GB per day and after that limit is reached the speed is throttled to 1000 kbps. Even the O2 Unlimited (International) plan, which offers 35 GB for 30 days, still has a data cap and ceases to supply full‑speed service once the 35 GB threshold is reached.

Travelers looking for more data can choose among fixed‑data plans. For example, Bouygues Telecom offers 120 GB for 30 days, Europe Orange provides 200 GB for 31 days or 500 GB for 90 days, and Global offers 100 GB for 31 days. These plans give larger amounts of high‑speed data without the daily throttle that applies to the so‑called unlimited plans.

eSimfly offers several eSIM plans that provide a phone number and SMS capability for travelers heading to Luxembourg. The plans range in price from about $17.84 USD for a 20GB 31‑day package to $125.54 USD for a 500GB 90‑day package, and validity periods vary from 15 days to 90 days. All of these packages include a phone number with a dialing code of either +33 (French) or +44 (British); these are not local Luxembourg numbers (which use +352). Calls can be made and received, and SMS can be sent and received, so both inbound and outbound voice and text communication are supported. Users who need specific confirmation about local coverage or function should contact eSimfly directly.

eSimfly supplies a range of data plans that cover Luxembourg. There are 12 single‑country plans whose coverage is limited to Luxembourg only, and 58 multi‑country plans that include Luxembourg among several other destinations. The plans span data caps from 1 GB up to 500 GB and are priced between $1.92 and $125.54. Some plans use a daily data cap, limiting the amount of data that can be used each day, while others use a fixed data cap that grants a total data allowance for the entire validity period.
