eSIMCard does not provide a genuinely unlimited high‑speed data plan for Gibraltar. All plans that carry the word “Unlimited” in their title have a fixed data allowance—such as 1 GB or 2 GB per day—after which the connection is throttled to 512 kbps or 2000 kbps. Because of this data cap, the plans are not truly unlimited for high‑speed use.
For travelers who need more data without the throttling, eSIMCard offers large fixed‑data options. For example, a 50 GB plan is available for 30 days and a 35 GB plan for 30 days, both covering Gibraltar and additional nearby countries. These plans provide a higher data allowance at a fixed price and can be a more cost‑effective choice for heavy data users compared to the daily “Unlimited” options.
