Saily eSIM Data Plans for Luxembourg

Saily does not provide a truly unlimited high‑speed data eSIM for Luxembourg. All plans that carry the word “UNLIMITED” in their name give a fixed daily data allowance—most commonly 5 GB per day, or 30 GB for a 30‑day period in global plans. After the allowance is reached, the speed is throttled to a reduced rate (typically 1024 kbps, and in the 5‑day Luxembourg variant to 1 kbps).

Instead, Saily offers fixed‑data plans that may be more economical for travelers who need a predictable data budget. For example, a 20 GB plan is valid for 30 days in Luxembourg, providing consistent speed throughout the period. Heavy data‑users may prefer one of these fixed plans, as they avoid the speed reduction that follows the daily limit in the “Unlimited” plans.

Saily does not offer an eSIM for Luxembourg that includes a phone number or SMS capability; only data‑only plans are available from this provider. Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice calls and messaging, but a local phone number or traditional SMS service is not provided.

There are 11 single‑country plans and 22 multi‑country plans that cover Luxembourg. The plans vary from $3.99 to $159.99 in price and from 1 GB to 50 GB of data, with validity periods ranging from 5 to 365 days. Saily’s 12 daily‑data‑cap plans replenish the data allowance each day, while the 21 fixed‑data‑cap plans provide a set amount of data that is used continuously throughout the validity period.
