Roaming4You does not provide a truly unlimited data eSIM for the United Kingdom. All of the plans listed for that destination have a data cap of 1 GB per day, regardless of the validity period, so the amount of high‑speed data is limited. The term “Unlimited” in the plan names refers only to the duration of the validity, not to an unlimited data allowance.
If you need a larger data allowance, Roaming4You offers fixed data plans that give 1 GB per day for a set number of days. Examples include a 1 GB/day plan for 1 day, 3 days, 5 days, 7 days, 10 days, 15 days, and 30 days, each priced at $1.00 per day. These fixed data plans can be more cost‑effective for most travelers unless you are an extremely heavy data user.
