RedSim eSIM Data Plans for Switzerland

RedSim does not provide a truly unlimited high‑speed data eSIM for Switzerland. All plans that carry the word “Unlimited” give a capped amount of data per day—5 GB/day for the Europe‑wide Unlimited plans and 3 GB/day for the Swiss‑only Unlimited plans—with speed reduced to 1 Mbps after the limit is reached. Travelers who need large high‑speed data budgets can instead choose fixed‑data plans, such as the 50 GB/30‑day or 20 GB/30‑day Swiss plans, which keep full 5 G speed for the entire balance.

RedSim does not provide a Switzerland eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are offered for Switzerland. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict access to these services, so it is advisable to verify that the apps you rely on are available in Switzerland before purchasing a plan.

RedSim offers 37 single country plans and 44 multi country plans that cover Switzerland. Prices span from around $1.79 to nearly $300, while data amounts range from 1 GB to 50 GB. The plans are split into fixed‑data packages, which provide a set amount of data for the entire validity period, and daily‑cap packages, which reset the data allowance every day – about 52 daily‑cap plans versus 29 fixed‑data plans. This gives travelers both price and data flexibility when traveling within Switzerland or across multiple countries.
