eSimfly eSIM Data Plans for United Kingdom

eSimfly does not provide a truly unlimited high‑speed eSIM for the United Kingdom.
All plans that carry “Unlimited” in their name give a maximum of 3GB per day and reduce speed to 1000 kbps once that limit is reached.

Travelers looking for high data allowances can instead choose fixed‑data eSIM options such as the Vodafone Travel (UK) plan with 500GB for 30 days or the Bouygues Telecom 120GB plan for 30 days. These plans offer larger data volumes without the post‑limit speed throttling, which can be more economical for heavy data users.

Yes, eSimfly sells eSIM plans that include a phone number with both voice and SMS capabilities for the United Kingdom. The plans are priced from $17.84 USD for a 31‑day 20GB package up to $125.54 USD for a 90‑day 500GB package, with validity lasting between 15 days and 90 days. The phone numbers come with either a +44 dialing code (local UK number on the O2 Travel Plus plan) or a +33 code (French number on Europe Orange and Bouygues Telecom plans). Each plan allows inbound and outbound voice calls and inbound and outbound SMS, so calls can be received and made and text messages can be sent and received. Users should confirm the specific features they need directly with eSimfly before purchase.

eSimfly offers 41 single‑country data plans for the United Kingdom and 61 multi‑country plans that include the UK as part of a broader coverage. The plans come in both daily data cap options, where the data allowance is reset each day, and fixed data cap options, giving a total amount of data over the validity period. Prices for these plans range from about $1.85 to $125.54, with data sizes available from 1 GB up to 500 GB, and validity periods spanning 3 days to 365 days. Some plans also support tethering and have a reduced speed mode of 1000 kbps.
