Simsima does not provide a truly unlimited data eSIM for Luxembourg. The plans that carry the word “Unlimited” in their name actually give 3GB of high‑speed data each day and reduce the speed to 1 Mbps after that daily limit is reached. For travelers who need more data without the speed reduction, Simsima offers fixed data plans such as 50 GB for 30 days or 20 GB for 30 days, which can be more cost‑effective for heavy data users.
Simsima 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 who need voice or text may 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, as some destinations may block or restrict specific apps.
Simsima offers 9 single‑country plans and 28 multi‑country plans available for use in Luxembourg. The plans range in price from $4.12 to $105.13 and include data caps between 1 GB and 50 GB. Among these, some provide a fixed amount of data for the entire validity period, while others use a daily data cap that limits usage each day.
