Mobile Broadband for Business UK 2026: 4G, 5G, Prices & Best Uses Quick Answer
Business mobile broadband gives you internet access over a 4G or 5G mobile network rather than a fixed fibre line.
It can be used as:
a main business internet connection
a temporary connection
portable Wi-Fi for staff
backup if fixed broadband fails
Our view: mobile broadband is excellent where flexibility matters, but it is not automatically a replacement for FTTP.
For many businesses:
Use case Best fit
Temporary site
5G hub
Mobile worker / travel
Portable MiFi
Small office with strong 5G
5G hub can work as primary connection
Shop / café / office relying on broadband
4G/5G backup
Large cloud-heavy office
FTTP or leased line normally better
Mission-critical site
Fixed connection + mobile backup

Key Takeaways
Business mobile broadband uses 4G or 5G rather than a fixed fibre line.
Three currently advertises unlimited-data business 5G broadband from £15/month ex VAT.
EE currently offers business mobile broadband from £10/month, with unlimited 5G hub plans at £28/month.
Vodafone offers portable hotspots and GigaCube business routers, including unlimited-data options.
Portable MiFi is best for travel and small teams.
5G hubs are better for fixed premises or temporary sites.
Mobile broadband speed can vary significantly with signal and congestion.
Unlimited data matters if mobile broadband will replace a fixed connection.
For businesses that cannot afford downtime, mobile broadband is often most valuable as failover.
Always test actual mobile signal at the premises before cancelling a fixed line.
What Is Business Mobile Broadband? Business mobile broadband connects to the internet using a SIM and mobile network – the SIM can sit inside:
a USB dongle
a portable MiFi device
a 4G router
a 5G router
a business gateway
The device then either:
connects directly to one computer
or creates Wi-Fi for several devices
Unlike fixed broadband, you do not normally need fibre installation or a phone line.
The Three Main Types of Business Mobile Broadband 1. Portable MiFi
A MiFi device is a small battery-powered mobile hotspot.
It is best for:
consultants
sales staff
events
travel
temporary meetings
It is convenient but usually less suitable as the permanent internet connection for an entire office.
2. 4G/5G Business Hub
A larger hub plugs into mains power and provides Wi-Fi to a larger number of devices, so better suited to:
small offices
construction sites
pop-up retail
temporary premises
businesses waiting for fibre installation
3. Mobile Backup/Failover
A router automatically switches to a mobile connection when the main broadband line fails – for many businesses, we think this is the most valuable use of mobile broadband .
Our Review: When Mobile Broadband Makes the Most Sense Mobile broadband is strongest when it solves a specific problem:
It is excellent when installation speed matters
You can often get online simply by inserting a SIM, powering on a hub and finding a strong signal which makes it useful for:
new offices
building sites
pop-up stores
events
It can be excellent in strong 5G areas
Modern 5G performance can be more than enough for:
cloud software
video meetings
email
file downloads
EPOS
It is less predictable than fibre
This is the main limitation – performance changes with:
distance to mast
building materials
router position
local congestion
network load
This is why we would not cancel a working fibre connection solely because a phone gets a fast 5G speed test.
Three Business 5G Broadband Three currently has one of the most aggressive business 5G broadband propositions, and their current business offer includes:
unlimited UK data
4G and 5G connectivity
5G hub
average advertised download speed around 150Mbps in Three’s current measurement
no fixed line
no engineer visit
Current headline pricing:
From £15/month ex VAT on a 24-month unlimited-data plan.
Three also offers:
1-month
12-month
24-month
36-month
mobile-broadband contract options.
Our view: Three is one of the most interesting options if you want to use 5G as a genuine fixed-broadband alternative and have strong Three coverage.
EE Business Mobile Broadband EE has a broader range of mobile broadband hardware and data allowances.
Current EE product Data Monthly price
4G WiFi
10GB
£10
Smart 4G Hub 2
100GB
£22

Prices exclude VAT and current listed plans use 24-month terms.
The Smart 5G Hub 7 Pro currently advertises:
Wi-Fi 7
unlimited data
average download speeds around 146Mbps
Our view: EE is particularly attractive if you want better device choice or already use EE Business mobile.
Vodafone Business Mobile Broadband Vodafone offers two particularly distinct options:
Portable Mobile Wi-Fi
Its current 5G Mobile Hotspot starts from £13.33/month ex VAT on a 24-month unlimited-data plan, which is better suited to:
mobile teams
meetings
field staff
travel
Vodafone GigaCube
GigaCube is a larger 4G/5G router aimed at premises and teams – Vodafone currently says it can:
connect up to 64 devices
use 4G or 5G
operate on 30-day or 24-month plans
offer data allowances from 100GB to unlimited
reach speeds up to 1Gbps where network conditions allow
Our view: GigaCube is more relevant than a portable hotspot if you genuinely want mobile broadband to replace a fixed connection.
Three vs EE vs Vodafone Business Mobile Broadband
Provider Strongest use Current advantage
Three
Primary 5G broadband
Low unlimited-data headline price
EE
Wide device choice / business mobility
Range from basic 4G to Wi-Fi 7 5G hubs
Vodafone
Portable and fixed 5G options
MiFi + GigaCube range
We would choose by local signal first, provider second.
Mobile Network Priority Is Becoming More Important One of the more interesting 2026 developments is that business mobile connectivity is starting to become differentiated by network priority rather than simply data allowance.
EE now promotes Fast Lane features that can prioritise eligible business traffic during congestion.
Vodafone launched SuperMobile for Business in September 2026, using a dedicated business 5G+ network slice.
Vodafone says eligible SuperMobile customers can receive:
dedicated business capacity
up to 4x faster speeds in relevant conditions
a minimum 15Mbps download guarantee on eligible 5G+ FastTrack services
Our view: this is particularly relevant for mobile workers who rely on connectivity in crowded city centres, stations, airports or events.
Can Mobile Broadband Replace Fibre? Sometimes.
We would consider replacing a fixed connection where:
5G coverage is consistently strong
the business is small
usage is not extremely latency-sensitive
an unlimited plan is available
portability is valuable
We would generally keep FTTP where:
the office has many users
VoIP is critical
large uploads are routine
stable latency matters
the business cannot tolerate changing speeds
Our Rule: Test Before You Switch Before replacing fixed broadband with 5G:
Test the network inside the premises.
Test during working hours.
Test during busy periods.
Test where the router will actually sit.
Check upload as well as download speed.
Run video calls and VoIP tests.
Check whether performance changes materially over several days.
A single speed test is not enough.
Mobile Broadband as Backup For many businesses, this is where mobile broadband provides the clearest return.
If a shop loses its fixed broadband, it may also lose:
card payments
EPOS
online orders
VoIP
booking systems
A 4G or 5G backup connection can keep basic systems operating while the fixed-line fault is repaired.

Dongle vs Mobile Wi-Fi A dongle connects directly to one laptop or computer and a mobile hotspot creates Wi-Fi for several devices.
For most businesses, we think a hotspot or hub is more useful unless the requirement is strictly for one laptop.
Unlimited vs Limited Data Data allowance matters more than many buyers expect – a business can use large amounts of data through:
Teams and Zoom
cloud backups
software updates
video
file transfers
customer Wi-Fi
If mobile broadband is your main connection, we would normally favour unlimited data.
Business Mobile Broadband Costs Current business examples include:
Provider/product Current price
EE 4G WiFi 10GB
£10/month
Vodafone 5G Mobile Hotspot unlimited
£13.33/month
Three Business 5G Broadband unlimited

Prices exclude VAT and are current September 2026 examples. Contract terms and annual increases apply.
Watch Annual Price Increases Mobile broadband is not immune from contract price increases – current examples include:
EE plans publishing future March price increases
Three Business broadband rising by a fixed amount each April
Vodafone mobile broadband plans also having annual adjustments
Compare the total contract value, not just the first monthly price.

What About Rural Businesses? Mobile broadband can sometimes solve poor fixed-line availability.
But rural performance depends entirely on mobile coverage.
If 4G/5G is weak, alternatives may include:
FTTP through another network
fixed wireless access
satellite broadband
Satellite should be compared separately rather than treated as a form of mobile broadband.
Security Business mobile broadband can be secure when configured correctly, so use:
strong Wi-Fi passwords
WPA2/WPA3 encryption
VPN where needed
device management
firewall controls
Do not confuse business mobile broadband with unsecured public Wi-Fi.
What to Check Before Choosing Mobile Broadband
Which network has the strongest indoor signal?
Is 5G available at the actual premises?
What download speed do you get during business hours?
What upload speed do you get?
Is data unlimited?
How many devices must connect?
Do you need battery-powered portability?
Is this the main connection or backup?
What annual price rise applies?
What minimum term applies?
Does the router support Ethernet ports?
Do you need external antennas?
Would FTTP cost less over the full contract?
Compare Mobile & Fixed Business Broadband
Our Verdict: Is Mobile Broadband Good for Business? Yes. but we think its biggest strength is flexibility rather than outright speed.
Our recommendations are:
Best for portable work: MiFiBest fixed-line alternative: 5G hub with unlimited dataBest use for most established businesses: broadband backupBest for temporary sites: 5G hubBest for mission-critical offices: fixed connection + mobile failover
Three currently stands out on headline unlimited 5G pricing, EE offers the broadest-looking business device range, and Vodafone provides a strong split between portable hotspots and larger GigaCube routers.
But network coverage at your exact site matters more than the brand name.
We would rather buy a slower-looking plan from the network that delivers a stable indoor signal than the cheapest “5G” package from a network that performs poorly at the premises.
