No eSIMX plans provide unlimited data for Switzerland. eSIMX offers fixed data plans with specific limits, such as the Switzerland 30GB 7Days plan and the Europe 100GB 30Days With Calls plan, which give a hard data cap. If a traveler needs a larger allowance, they could choose a higher‑cap plan like the Europe 100GB 30Days With Calls, which may be more cost‑effective unless they are an extremely heavy data user.
