Facts from official sources and the press, each with the date we last checked it.
EU roaming rules no longer cover the UK
Since Brexit took effect on 1 January 2021, the EU’s roaming rules no longer apply in the United Kingdom, according to Belgium’s telecoms regulator BIPT. EU operators may therefore add a roaming surcharge for calls, texts and data in the UK; some still apply roam-like-at-home there voluntarily. Check your own operator’s terms before you travel.

Vodafone and Three are now one company
Vodafone UK and Three UK completed their merger on 31 May 2025, forming VodafoneThree, owned 51% by Vodafone and 49% by CK Hutchison. The company plans to invest £11 billion over ten years, including a 5G Standalone network. Our UK plans list EE and Three, as shown in the network table on this page.
London Underground: mobile coverage is growing
In June 2026, TfL said around 60 per cent of the Tube’s underground stations had 4G and 5G coverage, with new tunnel sections on the Bakerloo, Metropolitan, Circle and District lines, and the whole network due by the end of 2026. EE, Three, Vodafone and Virgin Media O2 all take part. On stretches not yet covered, expect no signal between stations.
999 and 112 both work from mobiles
999 and 112 both reach the UK emergency services. GOV.UK says 999 calls from mobile phones automatically switch to another network if yours is unavailable, and suggests trying 112 if 999 does not connect. Texting 999 works only after registering in advance by SMS from your phone, which a data-only eSIM cannot do, so plan to call.

United Kingdom eSIM: common questions
- How much does an eSIM for United Kingdom cost?
- Plans for United Kingdom start at $2.13 for 1 GB valid for 1 day. The largest gives you 50 GB for 30 days at $36.55. Prices are in US dollars and are the final amount you pay.
- Which mobile networks does the United Kingdom eSIM use?
- In United Kingdom the plans run on EE and 3. Your phone connects to whichever is available where you are.
- Does the United Kingdom eSIM support 5G?
- Yes. 5G is listed for EE. You get it where the local network has 5G coverage and your iPhone supports 5G; elsewhere the eSIM uses the fastest network available.
- Can I use the same eSIM in other countries?
- The plans on this page work in United Kingdom only. If your trip continues, the Europe plan covers United Kingdom and 34 other countries on one eSIM, from $2.24.
- When does my United Kingdom plan start?
- When the eSIM first connects to a network in United Kingdom, not when you buy it — so you can install it at home before you travel.
- Does the United Kingdom eSIM give me a local phone number?
- No. These plans are data-only: mobile internet, not a local phone number, and no calls or SMS. Your usual number stays on your iPhone.
- How do I buy a United Kingdom eSIM?
- On this website or in the Voyafi app: pick United Kingdom, choose a plan and pay once. You confirm your phone supports eSIM before you pay, then install the plan with one tap.
- I live in the EU. Is mobile roaming free in the UK?
- Not automatically. EU roaming rules have not applied in the United Kingdom since 1 January 2021, so your operator may charge extra there, although some still include the UK voluntarily. If yours charges, a UK data eSIM is one alternative; it adds mobile data only and does not replace your home number for calls and texts.
- Will I have mobile data on the London Underground?
- On a growing part of it. TfL reported in June 2026 that around 60 per cent of underground Tube stations had coverage, aiming for the whole network by the end of 2026. Its list of covered stations includes Elizabeth line stations such as Paddington, Bond Street, Tottenham Court Road, Liverpool Street and Canary Wharf. All four UK mobile operators take part.
