eSimfly does not have any eSIM plan that offers truly unlimited high‑speed data for Gibraltar. The provider’s available packages for Gibraltar are fixed data plans that come with a set data allowance and a validity period. For example, the “Gibraltar Unlimited 3 Days” plan offers 3 GB per day for 3 days (a total of 9 GB) with a reduced speed after the daily cap is reached, while the “O2 Unlimited (International)” plan supplies 35 GB for 30 days without any speed reduction.
Users who need a larger or longer‑lasting data allocation can also choose from plans such as the 120 GB bundle at 30 days, the 100 GB plan at 31 days, or the 60 GB plan at 30 days. These fixed‑data options are typically more cost‑effective for travelers who want a predictable amount of high‑speed data during their trip.
