ZenSim does not provide a genuinely unlimited data eSIM for Luxembourg. All of its listed Luxembourg plans have a set data amount or a daily quota. For example, the Luxembourg 20GB plans give 20โฏGB of highโspeed data for 10 or 30 days, and the Luxembourg 10GB plan supplies 10โฏGB for the same durations. Choosing a fixedโdata plan can be more costโeffective than a nominal โunlimitedโ name, because once the allocated amount is used the speed will be throttled or the service will stop. The listed Luxembourg Unlimited STANDARD plans offer a daily allowance of 3โฏGB for 10 or 30 days, after which the speed is reduced; they do not deliver unmetered highโspeed data.
