Yesim sells unlimited data eSIM plans for Spain with validity periods ranging from 1 day to 30 days. The prices start at $8.12 USD for a 1‑day plan, rise to $27.85 USD for seven days, $40.61 USD for fifteen days, and $49.89 USD for a full month. Each of these plans allows tethering and is marked “isUnlimited = true, ” but the speed can be throttled after heavy usage.
Typical unlimited plans state that speeds may be reduced under a Fair Usage Policy, so users may experience lower rates after consuming a large amount of data. For precise details on how much data can remain at full speed and when throttling applies, it is best to contact Yesim directly to confirm the terms for the Spain package.
