ZenSim does not offer a truly unlimited data eSIM for Switzerland. All plans that contain the word “Unlimited” in their name include a capped allowance of 3GB per day, after which the speed is reduced to a throttled rate; the plans are still price‑listed and valid for either 10 days or 30 days.
Travelers who need larger high‑speed data allowances can choose from ZenSim’s fixed‑data plans for Switzerland. For example, a 20GB plan is available for 10 days at $23.00 USD or for 30 days at $24.00 USD, while a 10GB plan is available for 10 days at $17.00 USD. These fixed data plans are generally more cost‑effective for most users unless extremely heavy data consumption is anticipated.
