SimOptions does not provide an unlimited data eSIM specifically for Switzerland. All available Switzerland‑focused plans feature a hard data cap, ranging from 50GB to 120GB, each tied to a fixed validity period.
If a larger data allowance is acceptable, fixed data plans are available. For example, the 120GB plan is valid for 30 days and the 100GB plan valid for 180 days. Choosing a fixed data plan can be more cost‑effective than purchasing a Pay‑as‑you‑go credit, unless a traveler expects to use far more data than the cap allows.
