KnowRoaming eSIM Data Plans for United Kingdom

KnowRoaming provides six single‑country data plans that cover the United Kingdom and a separate set of thirteen multi‑country plans that include UK coverage. The single‑country offerings vary primarily in data amount—from 1 GB to up to 10 GB on the most common paid options—and are priced between roughly $4.40 and $30, with validity periods ranging from 7 to 30 days. The multi‑country plans likewise feature a range of data caps, from 5 GB for basic itineraries to 100 GB for high‑usage travelers, with prices from about $20 up to $180 and validity periods spanning 7 to 180 days. Most plans use a fixed data allocation; some can be converted into daily caps if the provider’s terms allow, providing flexibility for short‑term stays versus longer trips.
