Wiiline does not provide a truly unlimited data eSIM for Switzerland. Every plan listed has a hard data allowance; after the specified amount the speed is reduced or high‑speed data stops.
For travelers needing large data volumes, Wiiline offers fixed‑duration plans such as 400GB for 30 days, 200GB for 30 days, 100GB for 30 days, and a 100GB + calls plan for 31 days. These options deliver a clear data cap and a set validity period.
