nextSIM does not provide a truly unlimited data eSIM for Gibraltar. The plans that carry the label “Unlimited” actually include a fixed high‑speed data allowance, such as 1 GB or 2 GB per day, after which the speed is reduced to 512 kbps or 2000 kbps. This means that high‑speed data is capped despite the name.
Travelers who need a larger data budget can choose from fixed‑data plans. For example, a 100 GB 30‑day Standard plan is available for $164.15 USD, and a 50 GB 30‑day Standard plan costs $138.18 USD. These options offer higher data volumes without the speed throttling that applies once the “Unlimited” limit is reached.
