No, mobineX does not offer a truly unlimited data eSIM for the United Kingdom. All plans that carry “Unlimited” in their name actually provide a limited high‑speed data allowance—1GB for Unlimited Standard and 5GB for Unlimited Gold—after which the speed drops to 128kbps or 1024kbps, respectively. Travelers who require more data can choose one of mobineX’s fixed‑data options, such as the 65.09GB plan valid for 10 days, the 100GB plan valid for 60 days, or the 150GB plan valid for 90 days, which give much larger data allowances at a cost that may be more economical for heavy‑data users.
