eSimfly eSIM Data Plans for United Kingdom

eSimfly does not provide a true unlimited data eSIM for the United Kingdom. All of the plans listed for the UK state a data cap of 3GB per day and a fixed validity period; after the daily cap is reached the speed is throttled to 1000kbps.

Travelers can instead select from a range of fixed data plans. For instance, the United Kingdom Unlimited 10 Days option offers 3GB per day for 10 days, while the United Kingdom Unlimited 30 Days plan provides the same daily allowance for 30 days. These fixed‑data plans may be more cost‑effective for users who need a predictable amount of high‑speed data during their trip.

eSimfly offers several United Kingdom eSIM plans that include a phone number and SMS capability. The plans range in price from $22.69 USD for the 20 GB option to $42.47 USD for the 120 GB option, and validity periods vary from 15 days to 30 days. The Bouygues Telecom plans provide a phone number with dialing code +33, which is a French number, while the O2 Travel Plus (UK) plan offers a local UK number with dialing code +44. All plans support inbound and outbound voice calls as well as inbound and outbound SMS.

Users can make and receive calls and send and receive text messages on any of these eSIMs. If a specific type of number or messaging feature is required, it is advisable to confirm the details directly with eSimfly before purchasing.

eSimfly offers 37 single‑country plans and 57 multi‑country plans that cover the United Kingdom. The United Kingdom‑specific data plans typically price between $1.99 and $121.38 and provide data caps from 1 GB to 120 GB. Within the catalog, 24 plans feature a daily data cap—the data allowance resets each day—while 70 plans provide a fixed data cap that is valid for the entire duration.
