In short
5G for business means using fifth-generation mobile networks for faster data, more capacity in busy places and lower latency. The bigger step is 5G Standalone, which several UK networks brand as 5G+: it runs on a new 5G core and enables network slicing and priority features. To use it you need a compatible device, SIM and plan.

What 5G changes for a business
5G is the fifth generation of mobile network technology. For most businesses the benefits show up in three ways:
- More capacity. 5G can carry more traffic in the same place, which helps phones and card machines at busy stations, venues and events.
- Faster data. Large files, video calls and cloud apps are quicker on the move, which matters for field teams, sales staff and anyone working away from the office.
- Lower latency. Data takes less time to make the round trip, which helps real-time applications such as video, remote monitoring and connected equipment.
- New ways to connect premises. 5G makes 5G business broadband (fixed wireless access) a realistic option for some offices, shops and temporary sites.
5G does not change everything. Ordinary voice calls, texts and email already work well on 4G, and the speed you get on any mobile network depends on signal strength, how busy the local mast is and the device in your hand. The practical approach is to make 5G Standalone support a requirement for every phone, tablet and router you buy from now on, and to target 5G at the teams and sites that gain most from it. We can help you plan that.
5G Standalone and 5G non-standalone
There are two kinds of 5G in the UK, and the difference matters for business features.
5G non-standalone (NSA) was the first type to launch. It uses 5G radio equipment but still relies on the 4G core network behind it. EE Business describes its standard 5G this way: 5G radio on a 4G core.
5G Standalone (SA) runs on a completely new 5G core network. That is what unlocks the features 5G was designed for, such as network slicing and lower latency. EE Business, Vodafone Business and VMO2 (for O2 Business) all brand their standalone service as 5G+, and the term 5G Standalone, or 5G SA, is used across the industry.
| 5G non-standalone | 5G Standalone (often called 5G+) | |
|---|---|---|
| Core network | Relies on the 4G core | New, dedicated 5G core |
| Network slicing | No | Yes, where the network offers it |
| Priority features | - | Where the network offers them, built on slicing, such as priority lanes for business traffic |
| What you need | A 5G device and a 5G-enabled plan | A device that supports standalone, a compatible SIM or eSIM, an eligible plan and coverage |
| Where it works | Wherever the network has 5G | Where the network has switched on standalone; elsewhere the device uses 5G or 4G |
When you are outside standalone coverage, a compatible device simply connects to the network's ordinary 5G or 4G instead, so moving to 5G Standalone does not leave staff without signal.

How each network describes its 5G
Each UK network sets out its own 5G plans. We describe them separately, in each network's own terms, rather than ranking them; the right choice depends on where your people work.
EE Business EE Business calls its 5G Standalone network 5G+ and describes it as running on a fully standalone 5G core, with no reliance on 4G, while its standard 5G uses 5G radio on a 4G core. EE Business also offers Fast Lane, which uses 5G+ network slicing to give priority when the network is congested; it is available on eligible plans, needs a 5G+ compatible phone and SIM, and only activates within 5G+ areas. See EE Business mobile phones and plans.
Three Business Three Business SIMs are 5G-ready: you can use 5G wherever Three has 5G coverage and your device supports it, and any Three SIM, including an eSIM, supports 5G in a 5G-compatible device. Three's business coverage checker shows 4G and 5G at any postcode. See Three Business.
Three's small print: "Our 5G coverage map meets Ofcom High Confidence standard. However, although these coverage results are accurate, the information is only a guide and doesn't guarantee service availability in a particular location. Coverage may vary depending on your device and whether you're indoors."
O2 Business VMO2 switched on 5G Standalone for business customers in February 2025, for customers on eligible tariffs with a compatible device and SIM, and said the upgrade enables network slicing. Its consumer site calls the standalone service 5G+, also known as 5G Standalone. We can supply O2 Business; see O2 Business mobile phones and network.
Vodafone Business Vodafone Business calls its upgraded network 5G+, powered by a new 5G core that it refers to as 5G Standalone. It describes SuperMobile for Business as a premium 5G+ plan with a dedicated 5G+ FastTrack, which uses network slicing to give a business's mobile data priority at busy times, and it also lists Network Boost and 5G+ Slicing for businesses that want priority on its network. We can supply Vodafone Business; see Vodafone Business mobile phones and network.

Network slicing and priority features
Network slicing is one of the main reasons 5G Standalone matters to business. A standalone network can divide its capacity into separate virtual "slices", each with its own performance characteristics, so traffic that needs to get through (card payments at a stadium, a broadcast feed, a control system) is treated differently from general browsing.
The networks are turning slicing into business features in different ways:
- Priority lanes on eligible plans, which give a line priority when the network is busy (see each network's section above for what it offers)
- Prioritised slices for a business, a dedicated share of network capacity for critical applications at busy times
- Private and dedicated networks for large sites such as factories and campuses, built on a dedicated 5G core
Priority features depend on the plan, the device and being in standalone coverage, and the networks set their own terms for them. We can help you work out whether a priority feature is worth having for the way your teams work, and confirm availability at quote.

What you need to use 5G Standalone
Being on a 5G plan is not quite enough. To use a network's standalone service, four things need to line up:
- A compatible device. Standalone needs the right components and software enabled by the phone's manufacturer. Vodafone Business, for example, says older devices are unlikely to be 5G+ ready. Check the network's compatibility list before you buy.
- Current software. Networks ask for the latest operating system update. Vodafone Business, for example, says you must have the latest software update on your device to use its 5G+.
- A compatible SIM or eSIM. Some older SIMs need replacing. Vodafone Business says Apple users with a physical SIM issued before April 2022, or an eSIM issued before January 2024, need a new SIM for 5G+; VMO2 asks for one of its latest SIMs or eSIMs.
- An eligible plan and coverage. Each network decides which plans include standalone access, and you need to be in a standalone area. Elsewhere the device falls back to ordinary 5G or 4G.
Two other points are easy to miss. Standalone features may not apply when you are abroad: Vodafone Business says its 5G+ is not available when roaming at the moment. And mobile device management can control network settings on company phones, so make sure your MDM profile is not switching 5G off; see mobile device management software.
For help choosing devices, see mobile phones for business and our business eSIM guide.
Where 5G pays off, and where it does not
5G earns its keep when your people or equipment need data in places where older networks struggle:
- Busy locations. Events, exhibitions, stations and city centres, where capacity runs out first.
- Field and mobile teams. Engineers, surveyors, estate agents and sales staff sending photos, plans and video from site.
- Taking payments on the move. Card machines and point-of-sale tablets at pop-ups, markets and events.
- Temporary and hard-to-reach sites. Construction sites, site offices and seasonal premises using 5G business broadband instead of waiting for a fixed line.
- Backup for the office. A 5G business router that takes over if the main connection fails.
- Connected equipment. Cameras, sensors and signage, using a business data SIM.
It matters less for staff who mainly make calls and send email from an office with good Wi-Fi. For those users, coverage where they work, the device and the account tools often matter more than the generation of network; our guide to business mobile coverage explains how to check.
Planning a move to 5G
You do not need to replace a whole fleet to get the benefit of 5G. A practical approach:
- List where your teams actually work and check 5G and 5G Standalone coverage there on each network's own checker
- Make sure every new phone, tablet and router you buy supports 5G Standalone, so it is ready when coverage arrives
- Replace older SIMs that do not support standalone when you next touch those lines
- Decide which users would benefit from a priority feature, if any, rather than paying for it on every line
- Review older devices and equipment that still rely on 2G, which the networks will switch off between 2029 and 2033
Mobile networks have already switched off 3G, and gov.uk says the operators will switch off their 2G networks between 2029 and 2033. If you have alarms, card terminals or telemetry on old SIMs, now is a sensible time to check them; see business mobile coverage for each network's 2G plans.

Frequently asked questions
What is 5G for business?
5G for business is the use of fifth-generation mobile networks for business phones, tablets, routers and connected equipment. It offers more capacity in busy places, faster data and lower latency, and 5G Standalone adds features such as network slicing and priority lanes on eligible plans.
Is 5G+ the same as 5G Standalone?
Yes, in the UK 5G+ is the brand that EE Business, Vodafone Business and VMO2 use for their 5G Standalone services. Standalone runs on a new 5G core rather than relying on the 4G core, which is what makes network slicing possible.
Do I need a new phone for 5G Standalone?
Possibly. Standalone needs a device whose hardware and software support it, current software, and in some cases a newer SIM or eSIM. Older 5G phones may not be ready for it, so check the network's compatibility list before buying. We can help you choose devices that are.
What is network slicing?
Network slicing divides a 5G Standalone network into virtual slices with their own performance, so priority traffic such as card payments or a broadcast feed is handled separately from general browsing. Networks offer it as priority lanes on eligible plans or as dedicated slices for sites and events.
Does 5G work abroad?
It can, where the local partner network has 5G and your network supports 5G roaming there, but standalone features may not. Vodafone Business, for example, says its 5G+ is not currently available when roaming. See our business roaming guide.
Is 5G worth it for a small business?
It can be if your team works in busy places, takes payments on the move or needs internet at sites without fibre. If staff mainly call and email from a well-connected office, coverage and account tools may matter more. Contact us and we can help you decide.
