mobineX does not provide an truly unlimited high‑speed eSIM plan for the United Kingdom. Plans that carry the “Unlimited” name in the catalog actually contain a fixed data allowance of 1 GB or 5 GB and, once that limit is reached, the speed drops to 128 kbps or 1024 kbps respectively. For travelers who need more data without the speed reduction, mobineX offers fixed‑data options such as the 150 GB for 90 days, the 100 GB for 60 days, and the 50 GB for 30 days plans, which keep standard high‑speed rates throughout the validity period. Choosing one of these fixed plans can be more cost‑effective for most users unless they are extremely heavy data consumers.
