No, yaySIM does not provide an unlimited data eSIM for Switzerland. The available plans are fixed data bundles, such as a 100GB plan that is valid for 180 days or a 50GB plan that can be used for 30 or 180 days. Choosing a fixed data plan can be more cost‑effective unless a traveler expects to use a very large amount of data beyond the bundle allowance.
yaySIM does not provide any Swiss eSIM plans that include a local phone number or SMS capability. Only data‑only plans are available for Switzerland, and travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to these services, so travelers should verify that the apps they rely on are accessible in Switzerland before purchasing a plan.
yaySIM provides 16 single‑country plans that cover Switzerland, and an additional 70 multi‑country plans that include Switzerland within their coverage network. The available plans span a price range from $2.21 to $134.71, a data cap range of 102 MB to 100 GB, and validity periods that can be as short as one day or as long as one year.
