Best business mobile phone 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, Vodafone), but also some slightly smaller ones you won’t want to miss (Plusnet, Virgin Mobile).

To create our list of the best business mobile phone providers, 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

Vodafone: best business mobile plan provider

Vodafone are hard to beat when you consider the range of business mobile plans and packages on offer. Their Rewards system, business customer expertise also make them stand out.

With the largest number of UK based stores, and an active customer service team to rival most others, they'll always be in hand to support your business.

VodafonePros – Generous Rewards scheme for pay-as-you-go customers, easy to get help (with 500 UK stores), business mobile experts, 30 day trial, perks

Cons – Slightly lower Ofcom customer satisfaction rating than rivals (but with help readily available)

Small business phone plans

Small business owners are well taken care of by Vodafone with a range of plans to suit most budgets and needs. The most popular ones are:

  • Vodafone Business Value – A straightforward solution for small businesses on a tight budget, including Business Traveller, data capping and Vodafone Secure Net.
  • Vodafone Business Extra – For the ‘always on' businesses that need to stay connected, get everything included in Business Value, plus extras like damage insurance and Vodafone Rapid (lost and stolen cover).
  • Vodafone Business Black – If you're running an ambitious start-up, you might need bundles of data, texts and minutes for your business trips abroad.

SIM Only Deals

Vodafone's SIM only plans are a great option if you want to keep your existing phone and save on minutes, texts and data.

The SIM only data plans are ideal for companies with fewer than 50 employees, and start from a tidy £11 a month, with no hidden costs. You can check Vodafone's data bundles out here.

Pay-as-you-go

Pay-as-you-go customers also get some nice perks and freebies – like the Freebie International Minutes plan which gives you more free international minutes the more you top up. You can flick through Vodafone's pay-as-you-go phones here.

Then there's a pretty generous Rewards loyalty scheme, where you get points for every top-up that you can put towards more calls and data, or even your next smartphone.

Coverage and Speed – 5/5

As one of the UK's biggest mobile providers, Vodafone runs its own network, offering 2G, 3G and 4G coverage across the UK.

OpenSignal rank Vodafone just a whisker behind EE and O2 for average broadband speeds and availability, so they're in the top three nationwide.

Customer Support – 4/5

In the latest Ofcom report, Vodafone received 11 complaints for every 100,000 customers, which is slightly above average.

That said, it's one of the easiest phone companies to get help from if things ever go awry. They've got 500 shops all over the UK, so there's bound to be one near you. You can find your nearest Vodafone store easily on their UK store finder.

Plus Vodafone offer a whole 30 days to try out your phone and coverage, and if you're not impressed you get a full refund. That's well above the typical 14 days most other companies will give you.

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.

SIM only plans
Small business owners can choose between EE's Essential plans or Max plans. They start at just £11 a month, and many have EU roaming included. Here's EE's full list of pay monthly SIM only deals.

Or if you'd rather go contract-free, why don't you have a nose through their pay as you go SIMs?

Coverage and Speed – 4/5

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 – we checked with neutral coverage experts OpenSignal and they rate EE Number One here, with top download speeds of 31.8Mbps.

Customer Support – 5/5

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, the My EE Bill Analyser helps you stay on top of your bills.

We still have another four in-depth reviews of top providers to go. But if you’re struggling to compare contracts, coverage, and customer support, just provide us with a few details and, in a couple of minutes, we’ll find the most suitable plan for your business.

How do I choose the best business mobile phone provider?

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 EE'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

Read this far and still don’t know which is the right business mobile provider for you? Let us help. Simply fill in our short questionnaire and we’ll match you with the most suitable providers for your needs.

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.

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.

5GB to 12GB mobile data is usually plenty for most small business owners and entrepreneurs.


Which business mobile plans offer the best coverage?

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.

Though EE wins here, it isn't far ahead of its top contenders: Vodafone and O2.
