Flysimio does not offer a plan that provides truly unlimited high‑speed data in Switzerland. The only plan that contains “Unlimited” in its name, Switzerland Unlimited, actually supplies a fixed allowance of 2GB per day for a 7‑day period and then reduces speed after the daily limit is reached. For travelers who need a larger data allocation, Flysimio offers fixed data plans such as the Switzerland 50GB 30Days and Switzerland 50GB 180Days plans. These plans give 50GB of high‑speed data valid for 30 days or 180 days respectively, and they can be more cost‑effective for users who do not require continuous, unlimited data usage.
