No, SimSima does not provide a truly unlimited data eSIM for Aruba. The only plan that carries “Unlimited” in its name is the “Unlimited – 7 days” plan, which limits usage to 3GB per day. After reaching that threshold the speed is reduced to 1000kbps, so the data amount is still capped and it is not a no‑limit data service.
For users who want a larger data allowance, SimSima offers fixed‑data plans such as 20GB for 30 days ($64.68 USD), 20GB for 365 days ($84.83 USD), or 10GB for 30 days ($39.25 USD). These plans have clear data caps and specified validity periods; if a user does not need extremely high volumes of data, a fixed‑data plan tends to give a better cost‑performance balance.
