The data tables for aloSIM show no plan with an “unlimited” data cap for the United Kingdom. The available UK plans list a fixed data amount: 50GB for periods of 10, 15, or 30 days, or 100GB for 180 days. These are the maximum high‑speed data allocations that the eSIM can provide.
If a traveler needs a larger data allowance, aloSIM offers fixed data plans such as the 100GB plan valid for 180 days or the 50GB plan valid for 30 days. Choosing one of these fixed‑data options can be more cost effective for most users, especially if the data consumption is not extremely heavy. However, none of the UK plans offer unlimited data.
