eSimfly eSIM Data Plans for United Kingdom

eSimfly does not provide a truly unlimited high‑speed data eSIM for the United Kingdom. All eSimfly plans that carry “Unlimited” in their name are defined by a fixed daily data allowance, typically 3GB per day, and once the daily quota is reached the speed is throttled to 1000 kbps. This means the high‑speed data is still capped, even though the plan can be used for the entire validity period.

If a larger data allowance is required, eSimfly offers several fixed‑data alternatives. For example, the O2 Unlimited (UK) plan gives 650GB for 30 days, the Europe Orange Holiday 200 GB plan provides 200GB for 30 days, and the Bouygues Telecom 120 GB plan supplies 120GB for 30 days. These fixed‑data options may be more cost‑effective for heavy data users than the capped daily plans.

eSimfly does offer eSIM plans for the United Kingdom that include a phone number and the ability to send and receive SMS. The plans range in price from about $19.08 for the 20GB Europe Orange Holiday 20 GB 30 days plan to $64.74 for the 200GB Europe Orange Holiday 200 GB 30 days plan. Validity periods are typically 15 or 30 days, with the shortest being the 15‑day Bouygues Telecom 20 GB plan.

Some United Kingdom plans use a local dialing code of +44, such as the O2 Travel Plus (UK) and O2 Unlimited (UK) plans, allowing both inbound and outbound calls and SMS in the UK. Other plans listed in the dataset use a French dialing code of +33, meaning the phone number belongs to France; these plans also provide inbound and outbound voice and SMS. Users should confirm the specific dialing code and desired capabilities directly with eSimfly before purchasing.

eSimfly offers 38 single‑country data plans that cover the United Kingdom and an additional 60 multi‑country plans that include the UK in their coverage. The available plans range in price from about $1.99 to $121.38, while the data caps span from 1 GB up to 650 GB. Options include both fixed‑data‑amount plans and daily‑cap plans, giving travelers flexibility between a set data allotment and periodic limits.
