Roamingo does not provide a true unlimited‑data eSIM for the United Kingdom. The only plan listed with the label “Unlimited” is Europe Unlimited for 1 day, which offers just 2GB of high‑speed data; after that amount the connection would be throttled, so it is not unlimited.
For travelers in the UK, Roamingo offers several fixed‑data options that are more cost‑effective unless a user needs an exceptionally large data allowance. Examples include United Kingdom 20GB for 30 days priced at $29.00 USD and United Kingdom 10GB for 30 days priced at $16.50 USD. These plans give a larger data supply and can be a better choice than the short‑term reduced‑speed “unlimited” offering.
