WonderConnect does not provide an unlimited data eSIM for Gibraltar. The available plans for the territory are fixed‑data bundles that must be used within a 30‑day validity period. For example, a 20GB plan costs $28.49 USD, a 10GB plan costs $16.99 USD, and a 5GB plan costs $11.49 USD; all are 5G and allow tethering.
Choosing a fixed data plan can be more cost‑effective for most travelers, unless the user is an extremely heavy data consumer who would prefer an unlimited option.
