Simfinity eSIM Data Plans for Luxembourg

Simfinity does not provide a truly unlimited high‑speed data plan for Luxembourg. The plans labeled “Luxembourg Unlimited” are capped at 1 GB of high‑speed data; after this limit the speed is reduced, so usage is not unlimited.

Instead, Simfinity offers fixed‑data alternatives such as the 20 GB plan valid for 30 days, priced at $15.80 USD, or the Euro Zone Pass with 50 GB and unlimited validity for $105.00 USD. These plans give travellers a large amount of data at a set price and can be more cost‑effective than purchasing a high‑priced unlimited plan, especially for users who do not consume extreme amounts of data.

Simfinity does not provide an eSIM for Luxembourg that includes a phone number or SMS capability. The only plans sold by Simfinity for Luxembourg are data‑only eSIMs, which allow you to use mobile data for internet access but do not support inbound or outbound voice calls or text messages. Travelers who need to communicate while abroad can instead rely on popular VoIP applications such as WhatsApp, Telegram or iMessage, which work over the data connection and provide voice and messaging functionality without a local phone number.

Simfinity offers 10 single‑country data plans that are limited to use only inside Luxembourg, and 27 multi‑country plans that include Luxembourg among several European destinations. Single‑country plans provide data that can be used exclusively within the country, whereas multi‑country plans grant access across the European network, offering greater flexibility for travelers who may need coverage in several nearby markets. Prices on these plans range from about $1.80 to $158, with data caps spanning from 100 MB up to 50 GB; validity periods can stretch from no expiry to a maximum of 180 days, and tethering is permitted on plans that specify it.
