Why we don't lock you to one network.
Most UK business mobile suppliers are network-specific resellers. They get the best margin from one network — usually the one they're contracted with — so that's the network they push regardless of whether it's right for your operation.
Telexico is different. We're not a network reseller; we're a UK business connectivity and communications provider who happens to source mobile contracts across all four UK networks (EE, Vodafone, O2, Three). The network you end up on is decided by what makes operational sense for your business — coverage at your sites, usage patterns of your team, contract terms that fit your operation — not which network pays us the best commission this quarter.
This matters because the four UK mobile networks really are different. EE has the broadest 5G rollout and strongest rural performance — best for field-service teams covering UK-wide territory. Vodafone has strong urban performance and the most generous international roaming for businesses with EU-heavy travel. O2 has competitive enterprise pricing and good general UK coverage. Three has the strongest unlimited data offerings but more variable rural coverage. For some businesses the right answer is "all of these" — different networks for different staff based on where they work.
UK businesses that want one comms supplier, not five.
Telexico business mobile makes the most sense for organisations where mobile is part of a broader comms estate.
Multi-product UK SMEs
Businesses already buying business broadband, VoIP, AI Receptionist or WiFi from Telexico — adding mobile to the same relationship eliminates one supplier, one bill, one set of renewal dates to track.
Field-service operations
Trades businesses, mobile workforces, multi-site retail with staff moving between locations. Mobile is operationally critical, coverage at specific UK sites matters more than headline price.
Microsoft 365 / Teams shops
Businesses running on Microsoft 365 with Teams Phone — the mobile SIM and Teams Phone mobile app work together. Same supplier engineers them as one system.
Mission-critical operations
Businesses where mobile is a backup path for VoIP, card payments, or cloud apps when fixed connectivity fails. Multi-network failover SIMs sit alongside the office FTTP + 4G/5G backup architecture.
EU + international travel teams
Sales teams, consulting firms, field engineers travelling across Europe or worldwide. Roaming-optimised contracts and network choice can save substantial money over standard pay-as-you-go roaming.
IoT and M2M deployments
Telematics, asset tracking, vending machines, ATMs, alarm panels — fixed devices that need always-on cellular connectivity. M2M SIMs with multi-network roaming for reliability.
What business mobile actually costs.
Indicative ranges across the four UK networks for standard business contracts. Specific quotes depend on user count, contract length, data allowances and which networks fit your operation.
Basic business SIM
Typical monthly: £8-15 per user.
Includes: unlimited UK calls + texts, 5-10GB data, business support.
Best for: office staff who don't use mobile data heavily, mostly UK domestic calling.
Mid-tier business SIM
Typical monthly: £15-25 per user.

Best for: typical UK SME office/field workers with hybrid working patterns.
Unlimited business SIM
Typical monthly: £20-40 per user.

Honest comparison · where each one wins.
EE Business
Strongest: broadest UK 5G coverage, best rural performance, strongest network for field-service operations covering UK-wide territory.
Weaknesses: typically the highest-priced of the four for like-for-like contracts; pricing pressure is real on multi-line deals.
Best for: field-service teams, businesses with rural sites, anyone prioritising coverage over cost.
Vodafone Business
Strongest: strong urban performance, best EU and international roaming inclusions on business tariffs, good enterprise support.
Weaknesses: rural coverage varies regionally; some areas of the UK have noticeably weaker Vodafone signal than EE.
Best for: businesses with international travel, urban-focused operations, EU-heavy customer base.
O2 Business
Strongest: competitive enterprise pricing, good general UK coverage, established business support team.
Weaknesses: 5G rollout slightly behind EE; some rural areas have weaker signal.
Best for: mid-size UK businesses prioritising value and reliable general coverage, public sector contracts.
Three Business
Strongest: best unlimited data offerings in the UK, competitive pricing on data-heavy plans, strong 5G in urban areas.
Weaknesses: rural coverage more variable; specific rural postcodes can have notably weaker Three signal than the other three networks.
Best for: heavy mobile data users, urban-focused workforces, businesses where unlimited data ROI matters.
The honest answer about choosing: there is no universal "best network." The right choice for your business depends on where your team actually works (run signal-check apps at your real sites, don't rely on coverage maps), how much data they use, whether international travel is part of operations, and what your typical monthly volume looks like. A carrier-agnostic supplier like Telexico can also give you a different network per user — sales team on Vodafone for EU roaming, field engineers on EE for rural coverage, office staff on O2 for cost. One supplier, mixed networks.
One relationship across the whole comms stack.
Most UK businesses end up with telecoms suppliers fragmented across multiple providers — broadband from one, VoIP from another, mobile from a third, WiFi from a fourth. The result: four contracts, four support relationships, four renewal dates, and finger-pointing when something cross-supplier needs fixing.
Buying mobile from your comms supplier consolidates this. Single account manager handles broadband, VoIP, mobile, WiFi, AI Receptionist, CCTV — one named UK contact who knows your operation end-to-end. Single bill rather than four invoices to process. Single set of contract terms with consistent renewal management. When something cross-product needs attention — Teams Phone calls dropping on mobile, mobile failover not engaging during fixed-line outages, VoIP mobile app not authenticating — one engineering team owns the whole stack rather than each supplier blaming the other.
For most UK SMEs the operational savings from supplier consolidation exceed any small per-line cost difference between a Telexico-sourced contract and going direct. The free Telexico audit reviews your existing comms estate (including any mobile contracts) and produces a consolidation plan — including where staying with your current mobile supplier after renegotiation is the right answer.

Frequently asked questions
What is Telexico business mobile and how is it different?
Telexico sources and manages business mobile contracts across the four UK networks (EE, Vodafone, O2, Three) on behalf of customers. We're carrier-agnostic — we don't push one network because we're a reseller for one network. We assess your usage patterns, coverage requirements at your specific sites, and operational needs, then procure the right network and contract for your operation. Same single Telexico relationship covers broadband, VoIP, mobile, AI receptionist and the wider comms stack.
Which network is best for UK business mobile?
Depends entirely on your location coverage and usage patterns. EE has the broadest UK 5G coverage and strongest rural performance. Vodafone has strong urban performance and international roaming. O2 has good UK-wide coverage and competitive enterprise contracts. Three has excellent unlimited data offerings but more variable rural coverage. The honest answer: there is no universal 'best' — the right network depends on where your team works, what they use mobile for, and what your monthly volume looks like. A multi-network supplier like Telexico can give you a different network per user if your team's coverage needs vary.
How much does business mobile cost in the UK?
Typical 2026 UK ranges. Basic business SIM (5-10GB data, unlimited calls/texts): £8-15 per user per month on 24-month contracts. Mid-tier (50-100GB data, unlimited everything): £15-25 per user per month. Unlimited business SIM (truly unlimited with fair-use caps): £20-40 per user per month. Handset bundles (phone + SIM combined): £25-80 per user per month depending on handset tier and contract length. Multi-network failover SIMs for critical operations: £30-50 per SIM per month. Real quote requires usage assessment.
Can I keep my existing phone numbers when switching?
Yes. UK number porting works the same for mobile as for landlines. PAC (Porting Authorisation Code) request via text to 65075 from your current SIM, port typically completes within 1 working day, no service gap. We coordinate the port with the gaining network and handle any contractual transition with your existing supplier.
What about international roaming?
All four UK networks include EU roaming on most business tariffs (post-Brexit treatment varies — some networks charge small daily fees in EU, some include it free up to fair-use limits). Worldwide roaming is typically charged at daily rates (£3-7/day depending on destination zone) or via dedicated international plans. For teams travelling regularly, a roaming-optimised plan or carrier choice can save significant money — we factor this into the recommendation when sourcing the contract.
What's the difference between business SIM-only and a handset contract?
SIM-only means you buy the handset separately (outright or via a separate finance arrangement) and just pay for the network service. Lower monthly cost, more flexibility, ideal if your team already has phones or you prefer to refresh handsets independently of contract cycles. Handset contracts bundle the phone with the network into one monthly cost — convenient, but ties you in for the contract length and typically works out more expensive over the full term. For most UK SMEs with established staff, SIM-only is the more economical choice.
Does business mobile work with my VoIP / Teams Phone setup?
Yes — and this is where buying mobile from your comms supplier actually adds value. Modern hosted VoIP and Microsoft Teams Phone both have mobile apps that turn the phone into an extension of your business phone system. Same caller ID, same call routing, same voicemail. The business SIM provides the data the app uses. If we're managing both your business mobile and your VoIP/Teams Phone, we engineer them to work together — call quality, app integration, presence sync — rather than treating them as separate services from separate suppliers.
Can Telexico help if we already have business mobile contracts?
Yes — we can audit your existing mobile estate (number of users, networks, monthly costs, data usage patterns, contract end dates) and produce a consolidation plan. Common findings: businesses paying for more data than they actually use, on networks with poor coverage at their actual locations, locked into auto-renewing contracts with embedded price rises, or running multi-network mobile estates that could be consolidated for cost savings. The audit is free and there's no obligation to switch — sometimes the honest answer is 'renegotiate where you are.'
