eSIMatrix does not currently provide an unlimited data eSIM for the United Kingdom. Travelers who need a larger data allowance can choose from fixed‑data plans, such as the United Kingdom 20 GB – 30 days plan priced at $12.04 USD, or the Europe 20 GB – 5 days plan for $19.00 USD, which covers the UK and 34 additional countries.
These fixed options can often be more cost‑effective than paying for high‑usage data on a per‑GB basis, especially for users who anticipate heavy data consumption but remain within the set cap.
