ZenSim eSIM Data Plans for Switzerland

ZenSim does not provide an unlimited‑data eSIM for Switzerland. All plans marked as “Unlimited” in the name actually supply 3 GB of high‑speed data per day for 10 days or 30 days, and no plan offers unlimited data for life or a day‑by‑day threshold. After the daily limit is reached, the speed is throttled, but the specific reduced speed is not listed in the available plans. For travelers who need more data, ZenSim offers higher‑capacity fixed plans such as the Switzerland 20GB for 10 days at $23.00 USD and the Switzerland 20GB for 30 days at $24.00 USD, or the Switzerland 10GB for 10 days for $17.00 USD. Choosing a fixed‑data plan can be more cost‑effective for moderate to heavy data users.

ZenSim does not provide a Switzerland eSIM with a phone number or SMS capability. Their Switzerland offering is limited to data‑only plans, so users cannot receive or send regular SMS messages or make calls that require a local mobile number. For voice and messaging, travelers can rely on internet‑based VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection without needing a traditional phone number.

ZenSim offers eight single‑country plans and eight multi‑country plans that include Switzerland. Across these options the price ranges from $11 to $57 for 10‑to‑30 day validity periods, and the data caps vary between 3 GB and 20 GB. Some plans use a daily data cap strategy while others provide a fixed data allotment; both types are available. Tethering is allowed on several of the offerings.
