Lumbus does not provide a true unlimited data eSIM for Switzerland. The plans that carry the name “Unlimited” give a daily data allowance of 3GB/day and after that limit is reached the speed is reduced to 1 Mbps.
Travelers who need more data can choose from fixed‑data plans that offer a set amount of high‑speed data for a specific validity period. For instance, the “Switzerland 50GB 30Days” plan gives 50GB of data for 30 days, and the “Europe (35 areas) 100GB 180Days” plan supplies 100GB over 180 days. Both plans use Lumbus’s 5G network throughout Switzerland.
