RedSim does not provide a truly unlimited data eSIM for Gibraltar. The plans that carry “Unlimited” in their name give high‑speed data up to 3GB per day; once that amount is reached the speed is throttled to 1 Mbps for the remainder of the day. These are fixed data plans with a set validity period.
If a traveler needs a larger data allowance, RedSim offers fixed data plans such as the Gibraltar 20GB 30 days plan or the Europe (41 countries) 50GB 30 days plan. These plans provide a hard data cap that must be used within the validity window, and they can be more cost‑effective for most users unless very heavy data consumption is expected.
