EtravelSIM does not provide a truly unlimited data eSIM plan for the United Kingdom. All available plans for the United Kingdom have a set data cap, such as 4GB per day, 10GB per day, or larger fixed amounts like 50GB for a 30‑day period. Plans that include “Unlimited” in their name still limit usage to 4GB per day and reduce the data speed to 128kbps after that limit is reached.
Travelers who need more data can choose a fixed‑data plan instead. For example, a 10GB daily plan for 10 days is priced around $39.99, and a 50GB plan for 30 days costs about $29.19. These fixed‑data plans give full‑speed access until the allotted data is exhausted, after which no further throttling occurs, often making them a more cost‑effective option for most users.
