eSimfly does not have a true unlimited high‑speed data plan for Switzerland. All listings for Switzerland let a traveler use 3GB per day for the chosen validity period, after which the speed drops to 1000kbps. If a higher data volume is needed, the provider offers fixed‑data options such as the Switzerland Unlimited 10 Days plan, which supplies 30GB in total, or the Switzerland 50GB 30‑day plan. These fixed‑data plans give large amounts of high‑speed data and can be more cost effective for most users.
