eSimfly eSIM Data Plans for United Kingdom

eSimfly’s U.K. packages that carry the word “Unlimited” are not truly unlimited; each plan provides a maximum of 3 GB per day of high‑speed data, after which the connection may slow down. There are no plans that grant unrestricted high‑speed data for the United Kingdom.

For travelers who need a larger, fixed data allowance, eSimfly offers options such as the 200 GB plan valid for 31 days, a 120 GB plan for 30 days, and a 100 GB plan also for 31 days. These fixed‑data plans give a broader data budget in exchange for a lower daily limit and may be more cost effective for high‑usage users.

eSimfly offers United Kingdom eSIM plans that include a phone number and both inbound and outbound voice calls as well as SMS. The plans range in price from $17.84 USD for Europe Orange 20 GB 31 days to $59.99 USD for Bouygues Telecom 120 GB 30 days, and the validity period is from 15 days (Bouygues Telecom 20 GB) to 31 days (Europe Orange 200 GB 31 days). All of these plans feature an international dialing code; the O2 Travel Plus (UK) plan uses +44 and provides a local UK number, while the other plans use +33, a French dialing code.

If a local UK number is required, the O2 Travel Plus (UK) plan is the appropriate choice, offering inbound and outbound voice and SMS. For users that do not need a UK-local number, the plans with the +33 dialing code still allow reception and sending of calls and texts. It is advisable to confirm the specific telephony capabilities and numbering details directly with eSimfly before purchasing.

eSimfly lists a substantial number of options for travelers heading to the United Kingdom.

Within the portfolio, 12 plans feature a daily data cap, whereas 82 offer a fixed data allowance; many of the plans also allow tethering.
