simpleSIM does not provide a truly unlimited data eSIM for Gibraltar. Although several plans are named “Unlimited, ” each offers only 1GB per day and after that limit the speed is reduced to 512kbps, so high‑speed data is still capped.
If you need more data, simpleSIM offers fixed data plans such as the eSIM Gibraltar 20GB + Calls & Texts (20GB for 30 days) or the eSIM Europe 50GB + Calls & Texts (50GB for 30 days, also covering many nearby countries). A 20GB worldwide plan is also available for 30 days or for a full year. These plans give a larger, clear data allowance before any speed reduction would apply.
