So, who are the top business mobile phone plan providers?

Our extensive testing found that bigger doesn’t always mean better. That’s why our Top 6 Business Phone Plan Providers includes only the most impressive of the big players (EE, BT, 02), but also some slightly smaller ones you won’t want to miss (Giffgaff, Plusnet, Virgin Mobile).

To decide, we focused on what our start-up entrepreneurs tell us are the 3 most important factors for small businesses. They were:

  • Value for money – While you’re still growing your business, you need to keep the bills in check. But as a savvy business owner, you know that even more important than price is value for money
  • Coverage & speed – You’re busy, you don’t have time to hang around for slow download speeds, or risk a make-or-break call not getting through. Below we even explain how to check your coverage for different providers before you join them
  • Customer support – With a great business phone provider on board, you shouldn’t have much to worry about. But when we’re talking about your business, you need to know you can get back on your feet as quickly and easily as possible

How do I choose which one’s right for me?

There are some questions you’ll want to ask yourself to help you pick the best business mobile phone provider for you. Let’s start with the easy ones:

  • Who needs the phone? – Maybe it’s just you, or if you want to put several employees on the plan, networks like BT can offer special rates
  • Is my business growing or pretty stable? – If you think you might benefit from being able to mix up your bundles, be sure to opt for a more flexible plan like Giffgaff’s and Plusnet’s commitment-phobe packages
  • Who is my current broadband provider? – With BT, Plusnet and Virgin Mobile, you can save on your monthly bills when you combine your business broadband with your mobile phone plan

Now, let’s turn to your chunkier questions…

How much data do I need?

Many small business owners spend most of their days hooked up to their Wi-Fi, so data usage may be less than you’d expect. But to give you an idea of how much data you’re likely to need, check which category you best fit into:

The light user

DataMain useTime
500MBWeb browsing (checking social media and uploading photos)15-20 mins/day
1GBWeb browsing (checking emails and uploading photos)40 mins/day

The mid-weight user

DataMain useTime
2GBWeb browsing (checking emails, social media and uploading photos)90 mins/day
4GBWeb browsing (checking emails, social media and uploading photos)3 hrs/day

The heavy user

DataMain useTime
12GBMedia streaming (music, films)1 hr/day
32GBWeb browsing and media streaming3 hrs/day
Unless you’re streaming daily films for your commute (remember you could always pre-download them over Wi-Fi), you’re unlikely to be a heavy user. 2GB to 4GB mobile data is probably ideal for most small businesses and entrepreneurs.

Which providers offer the best coverage in my area?

EE gets the trophy for coverage. Their network pioneered 4G (faster internet speeds) and they cover 75% of the whole of the UK.

But today even the smaller mobile network providers piggyback on the infrastructure of the largest suppliers, so the difference is smaller than you might expect.

To check which provider is best for where your small business is located, just tap your details into Ofcom’s coverage checker. You can get it for free on iPhone or Android.

Now, let’s dig in…


Who are the top providers of business mobile phones in the UK today?

02 – For fairer payment plans

02’s strength is their customer service – and as a big provider, you can expect great coverage to boot.

Value for money


02 welcomes small businesses with open arms via their dedicated Small Business Plan. You can choose between SIM-only, SIM+phone and PAYG (pay-as-you-go) deals.

SIM-only plans

Their SIM-only tariffs start from just £15 a month for 10GB (or £18 with VAT). Here is their top range for small businesses:

Mobile phone contracts

If you’ll need the full package, here are 02’s most popular devices for small businesses:

Samsung Galaxy S8 1GB£35.58
iPhone 83GB£43.75
Samsung Galaxy S930GB£60.33

Just remember these prices are excluding VAT, and some of their best-selling mobiles come with an upfront cost, typically between £30 and £50.


If you’d like to get your business a PAYG deal, 02 charges competitive rates: 3p/minute, 2p/text and 1p/MB.

Coverage & speed


O2 has its own network and offers 2G, 3G and 4G coverage. Coverage experts OpenSignal found that 02 customers got a 4G signal 74% of the time – beaten only by EE (with 79% access).

Customer support


As one of the UK’s largest mobile phone providers, customers can reach 02 from one of their hundreds of high street stores, where you’ll benefit from the expertise of the company’s ‘O2 Gurus’.

02 even aims to treat their customers like stars. With 02 Priority, you can expect many a perk like pre-sale tickets – and there’s also 02 Rewards which gives PAYG customers a percentage of your spend on credit.

Then there’s 02’s happy customers – on Ofcom they have a stellar customer satisfaction rating at 93% and only 3% have a reason to complain.

Or, to hear it from them:

BT Mobile – For a good all-rounder

bt logoPros – great coverage, good variety of business plans, shared employee plans, unlimited BT Wi-Fi access
Cons – no stores, hit-and-miss customer service

Value for money ★★★★
Coverage & speed ★★★★★
Customer support ★★★★

15 years after selling its mobile division to 02, BT Mobile got back in the game in 2015. Today, they are one of the most popular networks, serving everyone from small businesses to NATO and Unilever.

Value for money


On the surface, BT aren’t the cheapest providers of business mobile plans. But we found out that if you have your broadband, TV, landline and mobile services with them, you can save quite a few bob.

BT Mobile mostly offer SIM-only deals that you can pair with your existing handset, but you can also find some of the smartphone contracts on their books. Their SIM-only plans start from just £8 a month.

Here are their most popular plans for small businesses:

SIM-only plans

Mobile phone deals

DataMinutes /TextsMonthly
250MB250 mins & 250 texts£8
Samsung Galaxy S964GB£48
Samsung Galaxy Note864GB£53
iPhone 864GB£53

These phones can have upfront costs which range from £25 (for the iPhone 8) to £270 (if you can’t live without the iPhone X).

On top of these deals, BT broadband customers save £5 a month on their mobile plans. Small business owners can also build their own plans, and if you have 5 or more employees you can take advantage of these tidy packages:

  • Mobile Sharer – Create a personalised plan of unlimited UK minutes, texts and data for all your devices
  • BT One Phone Professional – Get the horsepower of an office phone with the freedom of a mobile packed with business features

Coverage and speed


As a virtual provider, BT Mobile doesn’t have its own phone network, but you can expect good 4G, 3G and 2G coverage because it’s hooked up to EE’s solid infrastructure.

Customer support


BT keeps its prices low by not having its own stores. But their staff are on hand if you need them on 0800 800 150 (or 150 from your BT Mobile) or through their website.

Giffgaff – For budget-friendly SIM-only packages

giffgaff logoPros – tiniest prices, customer-focused, ultra-flexible tariffs, no-commitment plans
Cons – few perks and freebies, less extensive coverage, online-only service

Value for money ★★★★★
Coverage & speed ★★★★
Customer support ★★★★★

Although you won’t see Giffgaff in many business mobile lists, small businesses and entrepreneurs actually make up the majority of their clientele. We find Giffgaff hard to beat for their diddy prices, so long as you don’t mind an online-only service.

Value for money


Giffgaff doesn’t work like most phone providers. Rather than contracts, they offer monthly pay-as-you-go SIM cards that you can load with credit or bundles of texts, minutes and data.

Their prices start at just £5 a month, which will get you 150 minutes, 100MB data and 500 free texts.

You can spend more to get more, but even costs outside your monthly allowance are reasonable – just 15p a minute in the UK, or 5p for texts. And if you get your whole team onto Giffgaff, you can all talk for free.

Most of all, Giffgaff is a flexible, no-nonsense phone provider. It couldn’t be easier to change your bundle, or stop completely, and you can even buy your business mobile from them. They’re all unlocked, SIM-free handsets, so you can even switch to another provider if you want.

Coverage and speed


Giffgaff is another virtual provider, but you’ll just piggyback on 02’s reliable network to get the 2G, 3G and 4G coverage you need.

Customer support


It’s rare for a telecoms provider to be loved by its customers, but that’s exactly what Giffgaff claims.

We don’t have hard data on Giffgaff’s customer rating because they are too small to be covered by Ofcom. But we do know they put customer satisfaction at the very heart of their business model.

With no contracts tying you in, they say their customers stay because they want to, not because they have to. It’s compelling stuff.

It’s worth noting, though, that this network provider is only able to offer such competitive prices by keeping a low profile. That means you can’t pop into a store if you need an urgent fix, but you can often get the help you need from the forums on their website.

So, if you are happy to receive online support only, maybe you too might fall in love with Giffgaff.

EE – For super speeds and back-up whenever you need it

ee logo sqPros – top 4G speeds, reliable coverage, shared family plans, stores up and down the country, range of incentives, free replacement for 24 months, UK-based customer service
Cons – shaky customer service, less budget-friendly than competitors

Value for money ★★★★
Coverage & speed ★★★★★
Customer support ★★★★

EE is the biggest mobile network provider and have the best coverage, hands down. That makes them ideal for the busy small business owner, who doesn’t have time to lose, although but expect rivals to offer more competitive prices.

Value for money


EE is unlikely to appear on any budget-topping lists, but if you value good coverage for your business needs, they’re a great one to consider.

Their top business mobile phone plans start at £18 a month for a SIM-only contract, but their rates are more competitive when you throw in the handset.

Here are their mobile phone plans for small businesses:

iPhone 8+15GB£49/month
Samsung S930GB£49/month
iPhone X100GB£64/month

Just note that some of these phones have small additional upfront costs (usually between £10 and £30), so be sure to check your deal.

Coverage and speed


EE pioneered 4G (super-fast wireless internet) and still offers the best download speeds and coverage – reaching 75% of the UK of all the business mobile phone providers. Don’t just take their word for it – even coverage experts OpenSignal confirm it.

Customer support


EE doesn’t have a leading reputation for top customer service. But we found that in the latest Ofcom report, they don’t fare too badly – generating just four complaints for every 100,00 customers. That’s lower than BT and Vodafone.

Perhaps that’s because EE offers a host of incentives – from free Apple Music or BT Sport streaming to helpful alerts to stop you eating up all your data too soon.

On top of that, with more than 500 stores up and down the country, EE is one of the biggest phone providers, so they’ll be there should your small business need them. They even offer free phone replacements if anything goes wrong in the first year, and My EE & Bill Analyser helps you stay on top our your bills. Here’s how:

Plusnet – For affordable, flexible SIM-only plans

plusnet resizedPros – value for money, flexible packages, reliable broadband
Cons – virtual provider, can be tricky to contact

Value for money ★★★★★

You probably know Plusnet as a broadband provider. But did you know they also offer SIM-only mobile phone deals? Plusnet is a great value option, especially if you are already a Plusnet broadband user.

Value for money


Plusnet customers rave about its value for money, with most SIM-only contract-holders paying under £10 a month.

These are their most popular contracts for small businesses and individuals:

DataMinutes /TextsMonthly
2GB1000 minutes / 2000 texts£7
3GB1500 minutes / Unlimited texts£9

Outside of these, you’ll pay reasonable rates: 33p a minute for your regular calls and 12.5p per text in the UK.

Coverage and speed


As a virtual provider, Plusnet uses EE’s phone network – and offers 2G, 3G and 4G coverage.

Customer support


Plusnet doesn’t have its own stores, so they can be that bit trickier to pin down. But if you need any help or advice, you can always reach them online or over the phone.

Virgin Mobile – For happy customers

virgin mobile logoPros – highest customer satisfaction, fastest helpline response rate, extensive coverage, seamless switch, access Virgin Media Wi-Fi hotspots

Virgin Mobile gets top marks for customer satisfaction, and will custom-build the best plan for your small business.
