eSIMCard eSIM Data Plans for Luxembourg

eSIMCard does not provide a truly unlimited data eSIM for Luxembourg. All of its plans for Luxembourg list a specific data cap, even when the plan name includes the word “Unlimited.” Those plans provide a limited amount of high‑speed data (for example 1 GB for 1 day or 1 GB per day for 7 days) and specify a reduced speed after the limit is reached, which means the data is not unlimited.

Instead, eSIMCard offers several fixed‑data plans that can meet higher usage needs. For instance a 20 GB data plan with a 31‑day validity is available for $14.35 USD, and a 100 GB plan can be purchased for $35.41 USD. For travelers who need many days of data, the 1 GB per day plans range from 5 days up to 30 days, or the 2 GB per day “Plus” variants offer higher daily allowances at higher prices. These plans provide predictable amounts of data and are often more cost‑effective than an “unlimited” name that actually caps usage.

eSIMCard does not provide a Luxembourg eSIM with a local phone number or SMS capability. The provider offers only data‑only eSIMs for Luxembourg, so travelers will not receive an inbound or outbound voice line or SMS service from the plan.

Users can still make calls and send messages by using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or limit certain apps or VoIP services, so it is advisable to verify that the applications you rely on are accessible in Luxembourg before purchasing a plan.

eSIMCard currently lists 31 single‑country plans and 184 multi‑country plans that include coverage for Luxembourg, offering a wide range of data options. The single‑country plans span roughly $1.39 to $89.20 USD, providing data caps between 1 GB and 50 GB, while the multi‑country plans range from about $1.39 to $395.07 USD with data caps from 1 GB up to 500 GB. Some plans are sold as fixed data amounts; others deliver a daily data cap that resets each day, giving travelers flexibility in how they consume data while abroad. Tethering is generally allowed on most plans, and reduced‑speed options (512 kbps or 2000 kbps) are available for a few of them.
