Key takeaways
The UK has fast 5G in its major cities and good 4G coverage across most of England, Scotland and Wales, though signal can be thin in the Scottish Highlands, rural Wales and parts of rural Northern England. The easiest way to stay connected is a Roamix UK eSIM, which activates on arrival and keeps your Oyster app, Google Maps and live rail updates working from the moment you land at Heathrow. Budget 5 to 10 GB for a two week trip.
- EE has the widest national coverage and the fastest urban 5G in the UK.
- A Roamix eSIM activates on arrival so you skip SIM kiosks and carrier roaming bills.
- The UK is largely cashless, and contactless payment with a bank card or phone wallet works almost everywhere in London.
- The UK is not in the Schengen Area. Visitors from most countries enter visa free for short stays but should check current UK entry requirements.
- Budget 5 to 10 GB for a two week trip, more if you tether a laptop or travel frequently by rail.
Best way to get data in United Kingdom
For nearly everyone visiting the UK, a Roamix eSIM is the simplest and cheapest way to stay online, with local network speed and no surprise roaming charges.
| Option | Best for | Good to know |
|---|---|---|
| Roamix eSIMRecommended | Best for: Most travellers | Instant activation, local network speeds, no roaming bill and nothing physical to collect. |
| Local physical SIM | Best for: Long stays needing a local number | Available at airports and convenience stores, but requires setup and swapping your home SIM. |
| Pocket wifi | Best for: Groups sharing one connection | Another device to charge and manage, with rental fees. |
| Carrier roaming | Best for: Very short trips with no setup time | The most expensive option since the UK left the EU roaming union. |
Free wifi is widespread in UK cafes, pubs, hotels and transport hubs, but registration is often required and speeds vary. Mobile data is more reliable for navigation and live transit information.
How much data you need
UK trips rely on TfL Go for London travel, the Trainline for rail bookings and Google Maps for navigating everything from the City of London to Highland roads. Add social sharing and the data adds up over a two week trip.
3 to 5 GB
Long weekend in London
TfL navigation, social media, bookings and photo sharing across a city break.
8 to 12 GB
Two week tour of England and Scotland
Heavy navigation while driving Highland roads, rail bookings and regular social sharing.
20 GB or more
Remote work or extended stay
Video calls, laptop tethering and cloud uploads across several weeks.
Data per hour, by activity
- Maps and navigation
- 5 MB
- Social media and browsing
- 100 to 150 MB
- Music streaming
- 70 MB
- Standard video streaming
- 700 MB to 1 GB

Download offline maps of the Scottish Highlands and rural Wales before driving, as live navigation consumes significant data and signal can be absent on remote roads.
How to set up a United Kingdom eSIM
A Roamix UK eSIM is best installed over wifi before departure. It activates automatically when you connect to a UK network on arrival, so you are online before you reach the Elizabeth line platform at Heathrow.
- 1
Buy your plan on the Roamix UK eSIM page before you travel.
- 2
Install the eSIM over wifi by scanning the QR code.
- 3
Keep your home SIM for calls and set Roamix as your data line.
- 4
Enable data roaming for the Roamix line only.
- 5
Land in the UK and the eSIM connects automatically to a local network.
Works on eSIM capable phones including iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy S models. The phone must be carrier unlocked.
The correct APN is configured automatically on most devices. If data does not start, apply the APN from your order and toggle airplane mode.
No data on arrival usually means data roaming is off for the Roamix line or the network needs manual selection. Restart the phone after checking both.
Visa and entry for United Kingdom
The UK is not in the Schengen Area. Visitors from most countries, including the US, Canada, Australia and EU member states, can enter visa free for up to six months. However, the UK introduced its Electronic Travel Authorisation (ETA) for visa exempt visitors from November 2024.
- eVisa or ETA
- Most non-visa nationals now need a UK ETA before travelling, costing around GBP 10 and applied for online. EU, EEA and Swiss citizens are included from April 2025. The ETA is linked to your passport and valid for multiple trips over two years.
- Passport validity
- Your passport must be valid for the duration of your stay. The UK no longer requires 6 months validity beyond the return date.
- Onward ticket
- UK Border Force may ask for proof of onward or return travel and sufficient funds to cover your stay.
Apply for your ETA online before departure, keep your confirmation email accessible offline, and use your Roamix eSIM to show it at the border if requested.
UK entry rules change. Always confirm the latest ETA and visa requirements at gov.uk before booking.
When you land in United Kingdom
0 of 5 done
How people message here
WhatsApp and iMessage are both widely used in the UK, alongside standard SMS. There is no single dominant chat app beyond these.
Do you need a local number?
You rarely need a local UK number as a tourist. A Roamix data line covers WhatsApp and app based calling for most situations, and most UK services accept international numbers.
Keep your home SIM active for SMS two factor authentication while using the Roamix eSIM for data, as some UK banking and booking apps send verification codes by text.
Airports in United Kingdom
LHR
London Heathrow Airport
London
Free unlimited wifi across all five terminals, though speeds slow during peak international arrival waves. Terminal 5 (British Airways) and Terminal 2 (Star Alliance) have the most reliable connections.
Activate your Roamix eSIM before landing so you can check Elizabeth line or Piccadilly line directions and tap in with your contactless card the moment you exit customs. The Elizabeth line runs direct from LHR Terminal 2/3 and 4/5 to Paddington and Liverpool Street in 30 to 35 minutes.
LGW
London Gatwick Airport
London
Free wifi across both the North and South terminals with no time limit. Coverage is good for arrivals use.

MAN
Manchester Airport
Manchester
Free wifi across all three terminals. Terminal 1 (main international) has the best speeds.
Manchester Airport connects to the city centre by Metrolink tram in 25 minutes. EE 5G in Manchester is among the strongest in the UK outside London. Pull up the Metrolink route map and buy your ticket via the Stagecoach Manchester app on Roamix data at the gate.
EDI
Edinburgh Airport
Edinburgh
Free wifi throughout the terminal. Speeds are acceptable for navigation and messaging.
Edinburgh Airport connects to the city centre by tram (Line 1, 35 minutes to York Place) or Airlink 100 express bus every 10 minutes (30 minutes to Waverley). EE 5G activates immediately in the terminal, so your accommodation navigation and the Fringe Box Office app are live before you collect your bag.

Getting around United Kingdom
The UK has one of the world's most extensive rail networks and London's Underground is the backbone of capital city transport. A connected phone is essential for live timetables, contactless fares and rideshare bookings.
London Underground and Elizabeth line
Tap your contactless bank card or phone wallet directly on yellow TfL barriers. The TfL Go app shows live arrivals and manages fare caps. 4G coverage is available on most Underground lines.
National Rail intercity trains
Connects cities across England, Scotland and Wales. Book on the Trainline or National Rail apps for best prices, and keep your eSIM active for live departure updates.
Rideshare and taxis
Uber, Bolt and local black cab apps operate across major UK cities, all requiring an active data connection to book and track rides.
Car rental
Essential for the Scottish Highlands, Cotswolds and rural Cornwall. Remember to drive on the left and use live navigation for country lanes.
Tap your contactless bank card or phone wallet directly on TfL barriers for the cheapest fares, capped daily and weekly. Use the TfL Go app for live arrivals and the Trainline app for intercity rail.
Money and payments in United Kingdom
The UK uses pound sterling (GBP). London is largely cashless, and contactless payment is accepted almost everywhere, including buses, which no longer accept cash at all.
- Cards and cash
- Cards and contactless wallets work in virtually all UK shops, restaurants and transport. Carry a small amount of GBP only for rural markets, some village pubs and car park machines.
- ATMs
- ATMs are widely available but many now charge a fee. Choose to be charged in GBP to avoid dynamic currency conversion fees.
- Payment apps
- Apple Pay and Google Pay are widely accepted across the UK, including on TfL transport. A connected Roamix eSIM keeps your wallet and banking apps working on the move.
- Tipping
- Tipping around 10 to 15 percent in restaurants is customary if service charge is not already included. Check your bill, as many London restaurants add a discretionary service charge automatically.
Daily budget
Budget travellers spend around 60 to 100 GBP a day, mid range 120 to 250 GBP, with London significantly more expensive than most regional cities.
Local tips for United Kingdom
- Language
- English is spoken nationwide, though accents and dialects vary dramatically. Welsh is co-official in Wales and Scottish Gaelic in parts of the Highlands. No translation app needed.
- Food
- London's food scene is among the most diverse in the world. Beyond the capital, look for traditional Sunday roasts, Scottish seafood, Welsh lamb and Yorkshire pudding. Book popular restaurants on OpenTable or Resy.
- Plugs
- 230V, Type G plugs

Safety and health in United Kingdom
The UK is generally very safe for travellers. Petty theft is the main concern in central London and at busy tourist sites. NHS emergency care is free to all visitors.
- Stay reachable
- Keep your Roamix eSIM active to monitor live transport alerts, navigate safely in unfamiliar areas and contact emergency services if needed.
- Health
- NHS emergency departments treat all patients regardless of nationality. For non emergency care, visitors may be charged. Travel insurance covering medical expenses is recommended.
- Tap water
- Tap water is safe to drink throughout the United Kingdom.
Networks and coverage in United Kingdom
The UK has mature, fast mobile networks in its cities and good 4G coverage along most main roads and rail lines. A Roamix UK eSIM connects to the strongest available local network the moment you land, giving you reliable data in London, Manchester, Edinburgh and beyond without SIM kiosk queues or carrier roaming fees.
EE
The widest national reach and the fastest urban 5G, particularly strong in rural England, the Scottish Highlands and Northern Ireland.
O2
Solid national coverage with strong 5G in London and major cities, and good rural reach across England and Wales.
Vodafone UK
Excellent urban speeds and competitive 5G in major English cities, with ongoing rural expansion.
- Typical speeds
- Expect 100 to 300 Mbps on urban 5G and 20 to 60 Mbps on regional 4G.
- 5G
- 5G is live across London, Manchester, Birmingham, Leeds, Edinburgh and Glasgow, expanding to smaller cities.
If your trip includes the Scottish Highlands or rural Wales, choose a Roamix plan on the EE footprint for the widest rural reach.
The Scottish Highlands, rural Wales, Dartmoor and parts of the Yorkshire Dales have genuine coverage gaps on all networks. Download offline maps before driving in remote areas. UK networks use widely supported LTE and 5G bands compatible with most modern unlocked phones, so a Roamix eSIM works on virtually any recent device.
Where to go in United Kingdom
The UK packs centuries of history, world class museums, stunning national parks and one of the world's great cities into a small island nation. A connected phone is essential for navigating the London Underground, booking National Rail tickets and finding your way through the winding streets of Edinburgh's Old Town.
Best time to visit
May to September offers the best weather, with long daylight hours in summer. Spring and autumn are quieter and cheaper. Expect rain year round, particularly in Scotland and Wales.
London and South East England
The capital's world class museums, theatres, markets and architecture, plus the Kent coast, the South Downs and Windsor. London's British Museum, Tate Modern, Borough Market, Buckingham Palace and Greenwich Observatory sit alongside Oxford, Cambridge, Canterbury and Brighton.
- British Museum
- Tate Modern
- Borough Market
- Buckingham Palace
- Greenwich Observatory
Outstanding 5G across central London and good 4G throughout the outer boroughs and South East.

- Edinburgh Castle
- Royal Mile
- Arthur's Seat
- Isle of Skye
- Cairngorms National Park
Excellent in Edinburgh and Glasgow, with good 4G along main Highland routes including the North Coast 500 towns, but genuine dead zones in remote glens such as the Knoydart interior and on island crossings.
Wales and Cardiff
Cardiff is a compact capital with a Victorian civic centre, Principality Stadium and Cardiff Castle. Wales offers Snowdon (Yr Wyddfa), the Brecon Beacons, the Pembrokeshire Coast Path, Conwy Castle and the market town of Hay-on-Wye, home to more second-hand bookshops per square metre than anywhere on Earth.
- Snowdon (Yr Wyddfa)

Northern England: Manchester, Leeds and the Lake District
Manchester's music scene anchored by the Factory International venue, Leeds' cultural institutions, the Peak District between them, and the Lake District's glacial tarns and fells around Windermere and Scafell Pike. York's medieval walls and minster, Hadrian's Wall and the North York Moors complete the picture.
- Lake District (Windermere and Scafell Pike)
- Peak District (Mam Tor and Castleton)

The Albert Dock houses the Tate Liverpool, the Beatles Story museum and the Museum of Liverpool in a Victorian brick warehouse complex.
Signal: Excellent EE 5G throughout Liverpool city centre, the Cavern Quarter on Mathew Street, Albert Dock and the Royal Albert Dock UNESCO World Heritage waterfront.
40,000 interlocking hexagonal basalt columns formed by an ancient volcanic eruption on the Antrim coast and the most visited attraction in Northern Ireland. The geometric precision of the columns looks computer-generated but is entirely natural. The Causeway Coastal Route from Belfast to Ballycastle is one of the great coastal drives in the UK.
Signal: EE 4G at the Giant's Causeway visitor centre and main hexagonal basalt columns viewing platform. The Causeway Coastal Route cliff path has intermittent EE 4G on exposed sections.
The most north-western village on mainland Britain, accessible via 90 km of single-track road from Ullapool. Smoo Cave is a dramatic sea cave with an accessible outer chamber and a waterfall in the inner chamber (guided boat tours in summer).

Signal: Excellent EE 4G throughout Rye old town, Rye Harbour Nature Reserve and the surrounding East Sussex marshland roads.
A small Welsh market town on the England-Wales border with more second-hand bookshops per square metre than any other town on Earth: 30 bookshops for a population of 1,500. The Hay Festival in late May and early June brings global writers and 250,000 visitors annually; Bill Clinton called it 'the Woodstock of the mind'.
Signal: EE 4G throughout Hay-on-Wye town centre and the surrounding Brecon Beacons road network. Signal is stronger in town than on the open hill above Hay Bluff.
The most architecturally complete Georgian city in the world, built around the only natural hot spring in Britain. The Roman Baths beneath the city centre are one of the best-preserved Roman public buildings in Europe. The Thermae Bath Spa allows bathing in the same mineral-rich thermal water the Romans used, now from a rooftop pool.
Signal: Excellent EE 5G throughout Bath city centre, Roman Baths, Royal Crescent, Pulteney Bridge and the Thermae Bath Spa building.
A man-made network of shallow lakes and rivers in the flattest landscape in England, created by medieval peat digging and now home to over 300 species of birds. Hiring a self-drive electric dayboat from Wroxham or Potter Heigham is the defining Broads experience.
Signal: EE 4G in Norwich, Wroxham and all main Broads boating towns. Waterways between reed beds and open broads have intermittent EE 4G; some channels are off-grid.
