Simsima eSIM Data Plans for Switzerland

Simsima does not provide a truly unlimited data eSIM for Switzerland. The plans named “Unlimited” offer high‑speed data up to 3GB per day; once that amount is reached the speed is reduced to 1000 kbps.

If unlimited data is required, Simsima offers fixed‑data alternatives, such as a 50GB plan valid for 30 days or a 100GB plan valid for 180 days, both available for use throughout Switzerland. These plans deliver high‑speed data without the daily quota and without the speed reduction.

Simsima does not offer a Switzerland eSIM plan that includes a phone number or SMS. Only data‑only plans are available from the provider.

Travelers can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging. Some destinations may block or restrict these apps, so users should verify that the services they rely on are accessible in Switzerland before making a purchase.

Simsima provides a range of plans that can be used in Switzerland, split into single‑country offerings and multi‑country options.
For the single‑country lineup there are 12 different plans that cover only Switzerland, while the multi‑country catalogue offers 20 plans that include Swiss coverage among other destinations.

These plans vary in both duration and data allowance. Customers can choose from fixed‑data plans that give a set amount of data for a set period, or daily‑cap plans that reset the data allowance each day. Across the board the price ranges from under one US dollar to over $170, and the data cap spans from as little as 100 MB to as much as 100 GB, with validity periods from a single day up to six months.
