Which UK Mobile Networks Have Business Customers?

All four UK mobile networks — EE, Vodafone, O2 and Three — have dedicated business divisions and business mobile plans. They're not all equally competitive though, and the differences in coverage, pricing, EU roaming and contract terms matter a lot more on a business contract than they do on a personal one.

This is a quick straight-talking guide to who does what, who's strongest at what, and how to actually decide between them.

The four UK mobile networks at a glance

Network	Business division	Strongest for	Watch out for
EE	EE Business / BT Business	Coverage, 5G, multi-site	Premium pricing
Vodafone	Vodafone Business	Mid-size SMBs, included extras	Patchy rural coverage
O2	O2 Business	Free EU roaming, value	Slower 5G rollout
Three	Three Business	Big-data plans	Coverage gaps, sold direct only

These are the only four UK mobile networks. Every other "business mobile" supplier you'll see — Sky Mobile, Lyca, iD, Talkmobile, Plusnet — is an MVNO that piggybacks on one of these four. For business contracts you'll almost always want to be on one of the four directly.

EE Business

Owned by BT. The largest UK 5G footprint, the widest 4G coverage, and historically the network that wins where coverage is the deciding factor.

Best for: businesses with rural staff, multi-site operations, anyone who needs the best signal
Pricing: the most expensive of the four for equivalent allowances. You're paying for the coverage
EU roaming: not free — buy as a bolt-on per traveller
Contract minimum: 24 months

EE is the right pick when coverage at any one of your sites is borderline. It's overpaying if your team is purely in major cities and you don't need it.

Vodafone Business

Strong in the SMB segment, particularly for businesses with 10-100 staff. Coverage is generally good in cities and decent in suburban areas; the rural gap is more noticeable than on EE or O2.

Best for: mid-sized SMBs, anyone wanting included support extras
Pricing: mid-range, often competitive on multi-line deals
EU roaming: paid daily pass per device on the day of use
Contract minimum: 24 months

Vodafone Business often comes out cheapest on 5+ line deals because they're aggressive on the SMB end of the market. Worth quoting alongside O2 every time.

O2 Business

Owned by Virgin Media O2. Mid-range pricing, strong urban coverage, and the only one of the four that still includes free EU roaming on business plans.

Best for: businesses with EU travel, value-focused teams, anyone who needs the O2 Priority perk
Pricing: lower than EE, similar to Vodafone for like-for-like plans
EU roaming: free — Roam at Home gives 25GB EU data plus inclusive minutes and texts
Contract minimum: 24 months

O2 wins more business comparisons than people expect because the free EU roaming is genuinely valuable for any team that travels even occasionally. EE and Vodafone both removed their equivalent in 2021.

Three Business

Three has dedicated business plans with strong data allowances at the price-aggressive end of the market. Coverage has improved a lot but is still the weakest of the four, particularly indoors and in rural areas.

Best for: high data users in cities, very price-sensitive teams
Pricing: typically the cheapest per GB
EU roaming: included on most plans (with daily fair use limits)
Contract minimum: 24 months
How to buy: Three business contracts are sold directly by Three. We compare EE, O2 and Vodafone for you and will tell you when Three is genuinely worth a separate look

A practical note — if you've got staff out and about a lot in places like North Wales, Cornwall, the Scottish Highlands or anywhere with patchy indoor coverage, Three usually isn't the right pick regardless of price.

How to actually choose between them

The honest answer: do a postcode coverage check at every location your team operates from before anything else, and rule out networks that don't deliver. Then quote the survivors against each other on price.

The order most businesses end up in:

Coverage check — eliminate any network that doesn't deliver at your sites
EU travel? — if yes, O2 likely wins on cost over the contract
5G priority? — if yes, EE has the widest 5G footprint
Total cost — including bolt-ons, line discounts and any setup credits
Contract terms — minimum 24 months across all four; check end dates and notice periods

This is what we do for every quote. We'll tell you which network actually wins for your specific business rather than push whoever's paying us most.

What "business plans" actually get you over consumer

Worth clarifying because the distinction surprises people:

Business support — dedicated business support line, usually with shorter wait times
Account management — a named contact for accounts of any size
Multi-line discounts — pricing tiers from 5+ lines onwards
Centralised billing — one bill for all your lines, allocated by department/cost centre if needed
Stricter SLAs — particularly important if you're on EE/BT for combined comms
Business-only handsets — some devices (Samsung XCover, ruggedised models) only ship to business
Faster repair turnaround — usually 24-48hr versus 5-7 days on consumer

Personal plans don't get you any of this even if your usage profile looks similar.

Frequently Asked Questions

Which UK mobile networks have dedicated business plans?

All four UK mobile networks have business divisions: EE Business (owned by BT), Vodafone Business, O2 Business (owned by Virgin Media O2), and Three Business. Every other "business mobile" provider is an MVNO that piggybacks on one of these four.

Which UK mobile network is best for business in 2026?

There's no single answer — it depends on coverage at your locations, whether your team travels in Europe, and your budget. EE wins on coverage, O2 on free EU roaming, Vodafone on SMB pricing for 5+ lines, Three on raw price-per-GB. Compare The Networks does the comparison for you across EE, O2 and Vodafone for free.

Do all UK mobile networks include EU roaming on business plans?

No. O2 still includes Roam at Home (25GB EU data plus inclusive minutes and texts) free on business plans. EE and Vodafone removed their equivalent free roaming in 2021 and now charge per traveller, per day or via a paid bolt-on. Three includes EU roaming on most plans with fair-use limits.

What is the minimum contract length for UK business mobile?

24 months across all four UK networks for new business contracts. Some upgrades and add-ons can be shorter, but the headline business mobile contract is 24 months minimum. There are no genuine 30-day or rolling business mobile deals from the major networks.

Can I buy business mobile from someone other than the four networks directly?

Yes. Independent comparison services like Compare The Networks quote business mobile from EE, O2 and Vodafone for free, and the networks pay us rather than you. This usually beats going direct to a single network because you see what each is willing to do to win your business.
