4G and 5G home broadband

4G and 5G home broadband vs fibre: when mobile internet is the better choice

5G home broadband is sold as a no-engineer, no-landline alternative to fibre, and in the right place it is exactly that. In the wrong place — a ground-floor flat behind thick walls, or a village at the edge of a mast's reach — it is a frustrating downgrade. The difference is not the network's marketing. It's the signal inside your home, at 9pm.

Quick answer

5G home broadband can match or beat part-fibre (FTTC/SoGEA) where 5G signal indoors is strong, but full fibre is usually faster, steadier at peak times and lower in latency. Test your signal at the address first, check for fair-use limits or speed caps, and prefer a short contract.

If full fibre is available and you plan to stay put, full fibre is almost always the better connection. Wireless wins when you can't get fibre, can't wait for an installation, move often, or are stuck on slow copper.

This guide gives you a simple at-home test, spread over one day, to find out before you sign anything. It then compares 4G and 5G home broadband with full fibre and part-fibre on the things that actually matter: speed at busy times, latency, data limits, contracts and switching.

The one-day test: can wireless replace your fixed line?

You can do this test with a phone and a free speed-test app. It takes a few minutes each time, but you need to repeat it at different times of day, so plan on one day — ideally a weekday, when evening use is typical.

  1. Pick the network. Note which network (EE, VodafoneThree or Virgin Media O2) each home broadband deal runs on. Use a phone or SIM on that network for the test — borrow one if you need to.
  2. Stand where the router would go. Usually near a window, ideally upstairs. Test there, not on the doorstep.
  3. Run at least three speed tests on different occasions: one in the morning, one between 8pm and 10pm, and one late at night. The evening result matters most, because that's when masts are busiest.
  4. Note the latency (ping) each test reports. Lower is better for video calls and gaming.
  5. Note the signal. On Android, free apps can show signal values such as RSRP and SINR; on iPhone, the bars are a rough guide only. A dedicated router with bigger antennas may do somewhat better than a phone in the same spot, but plan on the phone result.
  6. Compare with what you need. Add up what your household uses at its busiest moment — the estimate below does the sums for you.

We deliberately don't give a single "good signal" number: what counts as good depends on the network's spectrum and how busy the mast is.

How this estimate works

We add up planning figures for each activity at the same moment — HD video 5Mbps, 4K 15Mbps (Netflix), a group video call 3.0Mbps down and 3.8Mbps up (Zoom), cloud gaming 25Mbps (NVIDIA), and our own allowance of 1Mbps for online gaming and for each person browsing — then double the total for Wi-Fi losses and short peaks. It is not a measurement of your connection. More in our methodology.

How the review works

You need at least three tests, including one between 8pm and 10pm, for a verdict. “Unlikely to be enough” means your evening and middle results are below the download need. “Borderline” means at least one result fell short, latency went above 100ms or varied by more than 50ms, or download varied by more than half between tests — these are our own rules of thumb, not industry standards. A phone test is only an approximation of a home router. More in our methodology.

How 4G and 5G home broadband work

A 4G or 5G home broadband router is, in effect, a powerful phone hotspot designed to stay on a windowsill. It holds a SIM card, connects to the nearest mobile mast, and shares that connection with your devices over Wi-Fi or Ethernet cables. There's no landline, no engineer visit and, usually, no installation beyond plugging it in. You'll also see it called fixed wireless access (FWA) or simply mobile broadband.

What decides your speed

  • Indoor signal strength and quality. Walls, double glazing with metallic coatings, and distance from the mast all weaken signal. A few metres and one floor can make a large difference.
  • How busy the mast is. Everyone connected to the same mast shares its capacity. This is why evening speeds can be far lower than morning ones — and why a speed test at 10am tells you little.
  • Which frequencies (bands) you can reach. Lower frequencies travel further and through walls better but carry less data; higher 5G frequencies carry much more but fade quickly indoors.
  • The router itself. Router category, antenna design and support for the bands your network uses all matter.

4G vs 5G vs 5G standalone

4G is almost everywhere: Ofcom's Spring 2026 update (data from January 2026) puts outdoor 4G coverage from at least one network at 96% of the UK's landmass, falling to 84% if you need coverage from every network. It's the safe fallback, but busy 4G masts can slow badly at peak times.

5G comes in two forms. Most early 5G was non-standalone (NSA): 5G radio riding on a 4G core network. It brings higher speeds but keeps some of 4G's delays. 5G standalone (SA) uses a fully 5G core, which is designed for lower latency and better handling of many users at once. All three UK networks are rolling it out, and all three now sell it as 5G+:

Network5G SA brandReported reach
EE5G+Around 54 million people (78% of the population), according to EE in August 2026; target 99% of the population by the end of March 2030
O2 (Virgin Media O2)5G+86% of the population across more than 700 towns and cities, according to O2 in 2026
Vodafone / Three (VodafoneThree)5G+ (Vodafone; launched in 2023 as 5G Ultra)Company target of 99% of the population by 2030 and 99.96% by 2034. As of November 2026, Vodafone's paid 5G+ add-on for phone plans is not available to Three, VOXI or SMARTY customers

Figures are each operator's own claims, checked in November 2026. Ofcom's independent January 2026 data puts 5G standalone coverage outside premises at between 49% and 85% of premises, depending on the network.

For home broadband, 5G SA matters most if you game, make lots of video calls, or live near a busy mast. Your router must support SA, and your plan must include it, to benefit. None of the 5G home broadband pages we checked from EE, Three and Vodafone said clearly whether the home plan includes 5G SA, so ask before you order if it matters to you.

5G home broadband vs full fibre vs SoGEA: side by side

The honest comparison isn't "5G vs fibre" in general — it's 5G at your address against the fixed line actually available at your address.

Example prices, checked on 8 November 2026. Three and Vodafone both listed 5G home broadband from £17 a month on a 24-month contract, rising to £20.50 from April 2027 and £24 from April 2028 (Three's price includes a £5 discount for paying by Direct Debit or another recurring payment). Twelve-month plans were £22, and Vodafone's one-month rolling plan was £29–£30. EE's 5G hub plans were listed from £45 a month with an upfront router charge. Prices change often, promotions come and go, and every one of these depends on coverage at your address — so treat them as a snapshot, not a quote. You can compare them with a fixed-line quote in the cost calculator below.

Where wireless wins

  • Speed of setup. You can be online the day the router arrives, which matters if you've just moved or an installation is weeks away.
  • Flexibility. Rolling or short contracts make it a good fit for renters, students and short lets — but check what happens if you move, because most plans are tied to one address.
  • Beating slow copper. If your SoGEA line struggles to reach double figures and you have good 5G indoors, wireless can be a dramatic upgrade.
  • No phone line needed. Nothing to install and nothing to keep paying for.

Where fibre wins

  • Consistency at busy times. A fibre line isn't shared with everyone near the mast, so evenings look much like mornings.
  • Latency and upload. For video calls, gaming, cloud backups and sending large files, full fibre is in a different league.
  • Big households. Several people streaming, gaming and working at once is exactly the load that exposes a busy mast.
  • Rights and redress. Fixed broadband comes with Ofcom's automatic compensation scheme (with signatory providers) and the speeds code's right to exit; mobile broadband doesn't.

Match your situation to the closest row. If two rows apply, the more demanding one wins.

A useful middle path: if you work from home and full fibre is available, take full fibre as your main line and keep a cheap 4G/5G router or data SIM as a backup. Our guide to backup internet shows how to set up automatic failover.

Networks, coverage and how to check properly

The UK now has three mobile networks: EE, VodafoneThree (the merged Vodafone and Three networks, still sold under both brands) and Virgin Media O2. Every other mobile brand rents capacity on one of them, so a cheaper brand on the same network can get similar signal at your address — though not always the same priority on a busy mast or the same access to 5G SA.

NetworkIts own brandsExamples of other brands that use it
EEEEBT Mobile
VodafoneThreeVodafone, Three, VOXI, SMARTYTalkmobile and Lebara (Vodafone network); iD Mobile (Three network)
Virgin Media O2O2, Virgin Mobile, giffgaffTesco Mobile, Sky Mobile

Host networks are taken from operator and trade-press reports checked in November 2026. Mobile virtual networks can change host, so check the brand's own terms.

Why coverage maps over-promise indoors

Operator maps and Ofcom's coverage checker predict signal from radio models. Ofcom's checker does give indoor predictions, but these are estimates for a 50-metre square, not your living room, and maps can't know how busy a mast will be at 9pm. Use the maps to shortlist networks, then test in person.

A sensible order:

  1. Ofcom's Map Your Mobile checker — an independent, like-for-like view of all networks for your postcode, with indoor and outdoor predictions and real-world performance data.
  2. Each operator's own checker — often more detailed for its own 5G and 5G SA.
  3. A real test inside your home, in the evening, using the one-day test above. This is the only step that tells you what you'll actually get.

The Vodafone–Three merger: what it changes for you

Vodafone and Three merged their UK businesses as VodafoneThree, and Vodafone took full ownership in July 2026. VodafoneThree has committed to invest £11bn in its network over the next decade, under a network plan the Competition and Markets Authority made legally binding when it cleared the merger in December 2024. The company's own target is 5G standalone for 99% of the population by 2030. Network sharing between the two grids is already live on thousands of sites, which can improve coverage for Vodafone and Three customers in some places. If a Three or Vodafone 5G plan failed your test a year ago, it may be worth testing again.

Plans, data, contracts, switching and faults

Unlimited, fair use and speed caps

The main 5G home broadband plans from EE, Three and Vodafone are sold as unlimited, but the terms differ. EE's fair-use policy treats use above 1,000GB a month as non-personal and allows it to be deprioritised at busy times. Vodafone's terms allow data to be deprioritised during congestion and cap speed at 50Mbps or 150Mbps depending on the plan and location. Three advertises no speed limits or data caps on its home broadband. Capped plans still exist on portable mobile Wi-Fi devices and data-only SIMs: when you reach the allowance you pay for more, slow right down, or wait for the next month.

Before you buy, find three things in the terms: the fair-use threshold (if any), what happens when you reach it, and whether the speed is capped.

How much data do you use?

Streaming video is by far the biggest user. Netflix says a stream uses up to about 3GB an hour in HD and up to about 7GB an hour in 4K. A household that streams 4K for three hours every evening is using over 600GB a month on that alone — fine on most unlimited home plans, but far beyond most capped data plans.

Estimate your monthly data use

Useful if a plan has a fair-use threshold or data cap.

Games, updates, cloud backups

If you currently have fixed broadband, your router or account page may show your monthly usage — the best evidence you'll get.

Contracts and price rises

Wireless home broadband is sold on rolling monthly, 12-month and 24-month terms. Start short if you haven't lived with wireless at this address before: a slightly higher monthly price for a rolling plan is cheap insurance if evening speeds disappoint. Check the money-back or returns period too: Three, for example, advertised a 30-day money-back guarantee in November 2026.

The pounds-and-pence rule applies here too. Since 17 January 2025, any price rise in a new contract must be stated in pounds and pence, with its date. Ofcom reports that in-contract rises announced for 2026 ranged from £1.80 to £2.50 a month for mobile phone contracts and £2 to £4 for fixed broadband. 5G home broadband rises can be at the top of that range: in November 2026, Three and Vodafone 5G home broadband plans rose by £3.50 a month each April, and EE's by £4. Add the rises written into your contract, plus any router charge, when you work out the total cost.

Each option’s total is the monthly price for every month in the period (promotional months at the promotional price), plus each price rise from its month onwards, plus one-off costs, plus equipment — either bought once or rented every month, never both — plus electricity if you give a power draw and a unit rate (watts × 24 hours × 30.4 days per month ÷ 1,000 × your rate). Amounts are worked out in pence. It doesn’t include early exit fees, credits, cashback or price changes not written into the contract. More in our methodology.

Switching to or from mobile broadband

Ofcom's One Touch Switch process is designed for switching fixed broadband and landline services. If you're moving to or from 4G/5G home broadband, ask your new provider whether it can manage the switch; if not, cancel the old service yourself and time it so you're not paying for both for long.

For anything with a mobile number attached, Ofcom's text-to-switch rules apply: text PAC to 65075 to keep your number, or STAC to 75075 if you don't need it. Your provider must reply within a minute, the code lasts 30 days, and you give it to your new provider, which arranges the switch. Mobile providers can't charge you for notice periods that run beyond the switch date.

Faults, compensation and complaints

This is the weakest part of wireless broadband compared with fixed. Ofcom's automatic compensation scheme covers residential fixed broadband and landline services only, so a mobile broadband outage doesn't trigger automatic payments. Ofcom's broadband speeds code, with its minimum guaranteed speed and right to exit, is written for fixed lines. What you do keep is the right to take an unresolved complaint to a free dispute resolution scheme (the Communications Ombudsman or CISAS) after six weeks, under Ofcom rules in force since 8 April 2026.

Getting the best signal

With wireless broadband, where you put the router matters as much as which plan you buy.

Router placement

  • Window first, upstairs second. A windowsill facing the mast's direction usually beats the middle of a room — EE, for example, recommends placing its router on or near a window sill. Upstairs usually beats downstairs.
  • Avoid metal and water. Radiators, mirrors, fridges, fish tanks and foil-backed insulation all absorb or reflect signal.
  • Try three spots and compare. Most routers have an app or web page showing signal quality. Move the router, wait a minute, and note the readings. Then run speed tests in the evening at the best spot.
  • Separate signal from Wi-Fi. The best place for mobile signal may be a bad place for Wi-Fi. If so, put the router at the window and use a mesh system or Ethernet to carry the connection around the house.

External antennas and outdoor units

If indoor signal is weak, an external antenna or a provider's outdoor unit may help — but only if your router has antenna sockets and the antenna suits your network's frequencies. Check first whether your provider offers an outdoor unit, and whether fitting third-party equipment affects your support or returns.

  • Window-mounted antennas are the easy first step: no drilling.
  • Directional outdoor antennas point at a specific mast and can make the biggest difference in rural areas, but need careful aiming and short, good-quality cables (long thin cables lose much of the gain).
  • Outdoor 5G units put the whole modem outside and run a single Ethernet cable indoors, avoiding cable losses altogether. Vodafone and Three both offer outdoor hubs where coverage needs it.

An antenna can't fix a mast that is simply busy. If your speeds vary a lot between morning and evening while the signal readings stay the same, congestion is the likely cause. Test before and after any change, and buy from a seller whose returns policy lets you send the antenna back if your evening speeds don't improve.

Before you fix anything outside, check the rules. Small antennas on houses are often allowed without planning permission, but limits on size and number apply, and stricter rules cover listed buildings, conservation areas, National Parks and flats. Check the Planning Portal (England), GOV.WALES (Wales), or your council's planning team (Scotland and Northern Ireland, which have their own rules). If you rent or own a leasehold flat, get written consent from your landlord or freeholder first.

Choosing a router

What to look forWhy it matters
5G with standalone (SA) supportNeeded to use 5G standalone (sold as 5G+ by EE, O2 and Vodafone) where your plan includes it; designed for lower latency
Support for your network's bandsA router that can't use your network's main frequencies will underperform
External antenna socketsLets you add an antenna later if signal is weak
Unlocked vs provider-lockedAn unlocked router lets you change network without new hardware
Ethernet ports and modern Wi-Fi (Wi-Fi 6 or newer)For wired devices, mesh systems and good in-home speeds

Provider-supplied routers are fine for most homes. Buy your own only if you need antenna sockets, want to switch networks freely, or the provider's router lacks SA support — and check that the provider allows third-party routers on the plan.

Lighter options: mobile Wi-Fi and phone hotspots

Not everyone needs a home router.

  • Phone hotspot (tethering). Free and instant, but it drains your phone battery, ties up your phone, and many plans cap how much data you can share. Fine for short outages and occasional laptop use; poor as a household connection.
  • Mobile Wi-Fi ("MiFi"). A pocket-sized battery router with its own SIM. Good for travel, a second home, or a backup, and it keeps your phone free. Fewer devices and weaker antennas than a home router.
  • USB dongles are largely obsolete for home use.

Frequently asked questions

Is 5G home broadband as good as fibre?

5G home broadband can match or beat part-fibre (FTTC/SoGEA) where 5G signal indoors is strong, but full fibre is usually faster, steadier at peak times and lower in latency. Test your signal at the address first, check for fair-use limits or speed caps, and prefer a short contract.

How does 4G or 5G home broadband work?

A router with a SIM card connects to a nearby mobile mast and shares that connection over Wi-Fi or Ethernet, like a phone hotspot built for the home. Performance depends on indoor signal, mast congestion and the router, so results vary by address and time of day. No landline or engineer is needed.

Is 5G home broadband unlimited?

The main plans from EE, Three and Vodafone are sold as unlimited, but terms differ: EE applies fair use above 1,000GB a month and Vodafone caps speed at 50Mbps or 150Mbps, and both can deprioritise traffic when the network is busy. Read the terms for any fair-use threshold, speed cap and what happens when you reach it.

Can I use 5G home broadband for working from home?

Yes, if your evening speed comfortably covers your needs and latency is stable. Upload speed and latency matter more than download for video calls. Keep a backup — at minimum a phone hotspot on a different network — for important calls.

Is 5G broadband good for online gaming?

It can be playable, especially on 5G standalone, but latency usually rises and varies more at busy times than on fibre. Competitive gamers are generally better served by full fibre where available.

Can I use my phone as home broadband?

Yes, but it is a poor long-term home connection. Phone hotspots drain battery, may be capped by your plan's tethering allowance, and serve fewer devices. They are best for short outages or light use. For daily household use, a dedicated 4G/5G router is more reliable.

Do I need a landline for 5G broadband?

No. 5G home broadband needs only mains power and a mobile signal. If you want a home phone, you can use a mobile or an internet-based phone service over the connection.

Will an external antenna improve my 4G/5G speed?

It can, when weak signal is the problem — particularly in rural areas. It needs a router with antenna sockets, an antenna that suits your network's frequencies, and short cables. It won't fix a mast that is simply overloaded, so check the signal readings before you buy one, and keep the receipt.

Can I take 5G home broadband with me when I move?

Not automatically. Most providers sell 5G home broadband for use at one registered address. If you move, the provider will check coverage at the new address; Vodafone, for example, lets you cancel without early termination fees if it can't serve your new home. Test the signal at the new home before you move.

Is 5G home broadband covered by One Touch Switch?

One Touch Switch is designed for fixed broadband and landlines. If you move to or from mobile broadband, ask your new provider whether it can handle the switch; otherwise cancel the old service yourself.

How we checked this guide

Prices, contract terms and coverage figures were checked against providers' own websites, Ofcom and the Competition and Markets Authority on 8 November 2026. Where a figure is an operator's own claim, we say so. We have not tested routers or connections ourselves, and NetSaver does not measure your speed or signal: the test review and estimates on this page only work with figures you enter. More detail is in our methodology.

What no guide can tell you is how busy the mast near you will be. That's why we ask you to test in your own home in the evening before committing to a long contract.
