Why Comparing Business Mobile Plans Saves UK Businesses an Average of 30%
Most UK businesses are overpaying for their mobile contracts. That is not opinion; it is arithmetic. OFCOM's 2025 Communications Market Report found that 62% of business mobile customers could reduce their monthly spend simply by switching to a plan that matches their actual usage. The average saving? Just over 30%.
The problem is straightforward. Businesses sign a contract, usage patterns change over two years, and nobody revisits the deal until renewal. Meanwhile, networks quietly apply annual mid-contract price rises, typically CPI plus 3.9%, that compound into significant overspend across multiple lines. A 10-handset fleet on the wrong tariff can leak thousands of pounds a year without anyone noticing.
Comparing plans properly means looking beyond the headline monthly price. You need to account for data allowances, 5G access, roaming charges, out-of-bundle rates, multi-line discounts, handset subsidies and those mid-contract increases. That takes time most business owners and IT managers do not have.

EE Business Mobile Plans 2026
EE remains the UK's largest mobile network and consistently tops independent speed and coverage tests. For businesses that depend on reliable, high-speed connectivity, particularly those with field-based teams or heavy data users. EE continues to set the benchmark in 2026.
SIM Only Plans
EE's business SIM only deals start from £7.00 per month (ex. VAT) for 1GB of data, scaling up through clearly defined tiers:
| Data Allowance | Monthly Cost (ex. VAT) | 5G Included |
|---|---|---|
| 1GB | £7.00 | Yes |
| 10GB | £10.00 | Yes |
| 25GB | £14.00 | Yes |
| 50GB | £18.00 | Yes |
| 100GB | £22.00 | Yes |
| Unlimited | £28.00 | Yes |
All EE business SIM only plans include 5G access at no extra cost, unlimited UK calls and texts, and access to the EE Business Hub for managing multiple lines. Contracts are available on 12 or 24-month terms, with 12-month plans carrying a slight premium.
Browse all EE business mobile deals on our dedicated comparison page.
Contract Plans (with Handset)
EE's handset contracts start from £26.00 per month and are available over 24 or 36-month terms. The upfront cost varies depending on the device, flagship phones like the iPhone 16 Pro and Samsung Galaxy S26 Ultra typically require a £29.99 to £99.99 upfront payment on mid-tier data plans.
EE also offers a device leasing option called EE Flex, which bundles the handset cost into a separate agreement, allowing businesses to upgrade devices independently of their airtime contract.
5G Coverage
EE leads the UK in 5G rollout. As of early 2026, EE's 5G network covers approximately 56% of the UK population across over 500 towns and cities. In urban centres, typical download speeds range from 150-300 Mbps, with peak speeds exceeding 1 Gbps in some locations. For businesses operating predominantly in cities and large towns, EE's 5G coverage is unmatched.
Pros
- Best 5G coverage and speed. consistently ranked first in RootMetrics and Opensignal reports
- 5G included on every plan. no need to pay extra for next-generation connectivity
- Strong business support. dedicated UK-based business account managers
- EE Business Hub. centralised management for multi-line accounts
- Reliable network. fewest dropped calls and widest 4G coverage as backup
Cons
- Premium pricing. EE is typically the most expensive of the four major networks
- Mid-contract price rises. CPI + 3.9% annual increases apply to most plans
- 12-month SIM only plans cost more. the cheapest pricing requires a 24-month commitment
- Roaming not included on basic plans. European roaming requires an add-on or higher tier plan
Verdict
EE is the right choice for businesses that prioritise network performance above all else. If your team works across the UK, regularly uses mobile data for cloud applications or video calls, and needs the most reliable connection available, EE justifies its premium. For cost-conscious businesses with lighter data needs, other networks offer better value.
Vodafone Business Mobile Plans 2026
Vodafone has carved out a strong position in the UK business mobile market by focusing on two areas where it genuinely excels: shared data pools for multi-line accounts and international roaming. For businesses with overseas operations or staff who travel frequently, Vodafone's proposition is compelling.
SIM Only Plans
Vodafone's business SIM only plans start from £8.00 per month (ex. VAT):
| Data Allowance | Monthly Cost (ex. VAT) | 5G Included |
|---|---|---|
| 2GB | £8.00 | No |
| 10GB | £11.00 | Yes |
| 25GB | £15.00 | Yes |
| 50GB | £19.00 | Yes |
| 100GB | £24.00 | Yes |
| Unlimited | £30.00 | Yes |
5G access is included on plans with 10GB or more. Lower-tier plans operate on 4G only. All plans include unlimited UK calls and texts.
See the latest Vodafone business mobile deals for current pricing.
Shared Data Pools
This is where Vodafone differentiates itself. The Vodafone Business Shared Data Pool allows you to purchase a single large data allocation and distribute it across all lines on your account. Rather than paying for 50GB per line when some users consume 80GB and others use 5GB, you pool everything together and eliminate waste.
For example, a 10-line account with a 200GB shared pool costs significantly less than giving each line an individual 25GB allowance, and no one runs out of data. The pool is managed through Vodafone's Business Portal, which provides real-time usage dashboards per line.
International Roaming
Vodafone includes roaming in 83 countries across its Roam Further destinations at no extra cost on plans of 10GB and above. This covers all of Europe plus popular business destinations including the USA, Australia, South Africa, India and the UAE. Staff can use their UK allowance abroad without bill shock, a genuine differentiator for internationally-focused businesses.
Contract Plans (with Handset)
Handset contracts start from £25.00 per month on 24-month terms. Vodafone offers a solid selection of devices and competitive upfront costs, particularly on Samsung and Google Pixel handsets where promotional pricing is often aggressive.
5G Coverage
Vodafone's 5G network covers approximately 38% of the UK population as of early 2026. Coverage is concentrated in major cities. London, Manchester, Birmingham, Bristol, Cardiff, Glasgow and Edinburgh all have strong 5G presence. However, in smaller towns and rural areas, Vodafone's 5G lags behind EE and even O2 in some regions.
Pros
- Shared data pools. genuine cost savings for multi-line accounts with variable usage
- Best roaming proposition. 83 countries included at no extra cost
- Business Portal. excellent account management and usage monitoring tools
- Competitive multi-line discounts. aggressive pricing at 10+ lines
- Strong enterprise support. dedicated account teams for 5+ line accounts
Cons
- 5G not included on cheapest plans. you need the 10GB tier or above
- 5G coverage trails EE. less extensive outside major cities
- CPI + 3.9% mid-contract rises. same annual increase structure as EE
- Basic plans lack roaming. only included on 10GB+ tariffs
- Customer service inconsistency. some businesses report variable support quality
Verdict
Vodafone is the standout choice for businesses with international travel requirements and those running multi-line accounts where data usage varies significantly between users. The shared data pool alone can save a 10-line business £50-£100 per month compared to individual allowances. If your business is UK-only and data needs are straightforward, other networks may offer better value.
O2 Business Mobile Plans 2026
O2 has built its business mobile proposition around flexibility. While other networks push you towards 24-month commitments, O2 offers genuine contract flexibility, including 1-month rolling plans for businesses that need agility. Combined with O2 Priority perks and a strong mid-range pricing position, O2 appeals to businesses that want a balance of value and freedom.
SIM Only Plans
O2's business SIM only plans start from £7.50 per month (ex. VAT):
| Data Allowance | Monthly Cost (ex. VAT) | 5G Included |
|---|---|---|
| 1GB | £7.50 | No |
| 10GB | £11.00 | Yes |
| 30GB | £15.00 | Yes |
| 50GB | £20.00 | Yes |
| 100GB | £25.00 | Yes |
| Unlimited | £30.00 | Yes |
5G is included on plans of 10GB and above. A key differentiator is that O2 offers these plans on 1-month rolling contracts as well as 12 and 24-month terms. The rolling contracts cost approximately £2-£4 more per month but provide complete freedom to upgrade, downgrade or cancel with just 30 days' notice.
Compare all available O2 business mobile deals on our dedicated page.
Flexible Contracts
O2's Flex proposition is genuinely useful for businesses with changing needs. Seasonal businesses, startups scaling rapidly, and companies onboarding project-based contractors all benefit from the ability to add or remove lines without penalty. You can mix contract lengths within a single account, some lines on 24-month deals for the best pricing, others on rolling monthly terms for flexibility.
O2 Priority Perks
Every O2 business line includes access to O2 Priority, which offers exclusive deals, pre-sale tickets to events and weekly freebies. While this might sound like a consumer gimmick, businesses report that staff genuinely value these perks, particularly in industries where recruitment and retention are challenging. It is a small but tangible benefit that costs the business nothing extra.
Contract Plans (with Handset)
O2's handset contracts start from £24.00 per month, making them competitive with Three and slightly cheaper than EE for equivalent specifications. O2 also runs the O2 Refresh scheme, which splits the handset cost and airtime into two separate agreements. Once the handset is paid off, your bill drops automatically, unlike bundled contracts where you continue paying the same amount after the device subsidy period ends.
5G Coverage
O2's 5G coverage sits at approximately 42% of the UK population as of early 2026, placing it second behind EE. O2 has been investing heavily in its 5G rollout and coverage has improved markedly over the past 12 months, particularly in secondary cities and larger towns. The network shares infrastructure with Vodafone through the CTIL joint venture, which has accelerated its expansion.
Pros
- Genuine contract flexibility. 1-month rolling, 12-month and 24-month options
- O2 Refresh. separated handset and airtime costs, bill drops when phone is paid off
- O2 Priority perks. staff benefit from exclusive deals and experiences
- Strong 5G rollout. second-best coverage behind EE
- Mid-range pricing. competitive without being the cheapest or most expensive
Cons
- Rolling contracts cost more per month. flexibility comes at a premium
- No shared data pools. each line has its own individual allowance
- Roaming charges apply in many destinations. European roaming included, but other regions cost extra
- CPI + 3.9% mid-contract increases. same annual uplift as other major networks
- 5G not on entry-level plans. cheapest tier is 4G only
Verdict
O2 is ideal for businesses that value flexibility over absolute lowest cost. The ability to mix rolling and fixed contracts within one account is genuinely useful, and the O2 Refresh structure ensures you never overpay for a handset you have already paid off. For businesses with straightforward, stable requirements, a 24-month deal on another network may save a few pounds per line, but O2's flexibility is worth paying slightly more for if your situation is likely to change.
Three Business Mobile Plans 2026
Three has always positioned itself as the value network, and in 2026 that remains its core strength. Three offers the cheapest unlimited data plans on the market, making it the go-to choice for data-hungry businesses. However, the network is also undergoing significant change following the completion of its merger with Vodafone in late 2025, and businesses should understand what that means for plans, coverage and pricing going forward.
SIM Only Plans
Three's business SIM only plans start from just £6.00 per month (ex. VAT), the lowest entry point of any major network:
| Data Allowance | Monthly Cost (ex. VAT) | 5G Included |
|---|---|---|
| 1GB | £6.00 | Yes |
| 10GB | £8.00 | Yes |
| 25GB | £12.00 | Yes |
| 50GB | £16.00 | Yes |
| 100GB | £20.00 | Yes |
| Unlimited | £24.00 | Yes |
Three includes 5G on every plan at no extra cost, matching EE's approach but at significantly lower price points. The unlimited plan at £24.00 per month undercuts every other network by at least £4.00 per line.
For full plan details, visit our Three business mobile deals page.
The Vodafone-Three Merger
The merger between Vodafone and Three (approved by the CMA with conditions in 2025) is the biggest development in the UK mobile market in over a decade. For business customers, the implications are significant:
- Combined network coverage. Three customers will gradually gain access to Vodafone's infrastructure, improving coverage in areas where Three has historically been weaker, particularly indoors and in rural locations.
- Pricing commitments. as a condition of the merger, the combined entity has committed to maintaining competitive pricing for at least three years.
- Plan migration. existing Three business plans will be honoured for the duration of their contract. Migration to unified plans is expected to begin in late 2026 or early 2027.
- 5G investment. the merged entity has committed £11 billion in network investment, which should significantly accelerate 5G rollout.
Contract Plans (with Handset)
Three's handset contracts start from £22.00 per month, the cheapest entry point for a contract plan with a device. The range of available handsets is comprehensive, covering all major manufacturers. Three also offers interest-free payment options on selected devices when spreading the cost over 24 or 36 months.
5G Coverage
Three's 5G coverage currently sits at approximately 34% of the UK population, the lowest of the four major networks. However, the merger with Vodafone is expected to accelerate this significantly. Three's 5G strength lies in its substantial mid-band spectrum holdings, which provide a good balance of speed and range. Where Three has 5G, speeds are competitive with EE, but the coverage footprint is simply smaller for now.
Pros
- Cheapest plans across the board. lowest SIM only and contract pricing
- Unlimited data from £24/mo. significantly cheaper than any competitor
- 5G on every plan. no tiered access, every customer gets 5G
- Merger benefits incoming. coverage improvements expected as Vodafone integration progresses
- No mid-contract price rises on selected plans. some plans offer fixed pricing (check terms carefully)
Cons
- Smallest 5G coverage footprint. 34% vs EE's 56%
- Indoor coverage weaker. historically Three's Achilles heel, though improving post-merger
- Merger uncertainty. plan structures and pricing may change as integration progresses
- Customer service under strain. merger integration has reportedly stretched support resources
- Roaming less generous. fewer included destinations than Vodafone
Verdict
Three is the clear winner for businesses where cost is the primary driver and data usage is heavy. The unlimited data plans are unbeatable on price, and with 5G included on every tier, there is genuine value across the entire range. The merger with Vodafone should address Three's historic coverage weaknesses over time. However, if your team works in rural areas or needs the absolute best network reliability today, EE or O2 may be safer choices until the merged network matures.
How to Choose the Right Business Mobile Plan
With four major networks each offering multiple plans, tiers, contract lengths and add-ons, choosing the right business mobile plan can feel overwhelming. Here is a structured framework to cut through the noise and find the right fit.
1. Assess Your Data Needs
Start by understanding how much data your team actually uses. Check your current provider's usage reports, most business portals provide per-line breakdowns. If your staff primarily use WiFi in the office and only need mobile data for emails and light browsing on the move, 10-25GB per line is usually sufficient. If your team works in the field, uses cloud applications, joins video calls on mobile, or tethers laptops to phones, you will need 50GB-unlimited per line.
For a detailed guide on right-sizing your data allowances, see our data usage guide or get a free quote.
2. Check Coverage in Your Areas
Network coverage varies significantly by location. A plan that is perfect on paper is useless if the network does not work where your team operates. Use each network's online coverage checker, but also ask colleagues and contacts in your area about real-world experience. EE leads on overall coverage, but there are pockets across the UK where O2, Vodafone or Three outperform it.
3. Set a Realistic Budget
Work out your total budget per line per month, including VAT. Remember to factor in mid-contract price rises, a plan that starts at £15/mo will likely be £17-£18/mo by the end of a 24-month contract due to CPI + 3.9% increases. If budget predictability matters, look for plans with fixed pricing or shorter contract terms.
4. Decide on Contract Length
Shorter contracts cost more per month but give you flexibility. Longer contracts lock in lower pricing but reduce your ability to switch. For most established businesses with stable headcount, 24-month contracts offer the best balance of pricing and commitment. For startups, seasonal businesses and those with fluctuating staffing, O2's rolling monthly contracts or 12-month terms provide valuable agility.
5. Consider the Number of Lines
The more lines you have, the more you can negotiate. Networks offer progressively better pricing at 5, 10, 20 and 50+ lines. If you currently have lines split across multiple networks, consolidating to one provider almost always unlocks better per-line pricing. See our guides for 5-line, 10-line and 20-line business mobile deals for current multi-line pricing.
6. Factor In Extras
Do you need international roaming? Vodafone leads here. Need flexible contracts? O2 is best. Want the fastest, most reliable network? EE. Need the cheapest unlimited data? Three. Match the network's strengths to your business's specific requirements rather than defaulting to the lowest headline price.

Business Mobile Plan Costs Breakdown
Understanding the true cost of a business mobile plan means looking beyond the monthly line rental. Here is a full breakdown of the cost components you need to budget for.
Full Cost Comparison Table
| Cost Component | EE | Vodafone | O2 | Three |
|---|---|---|---|---|
| Line rental (25GB SIM only) | £14.00/mo | £15.00/mo | £15.00/mo | £12.00/mo |
| Handset cost (mid-range, 24mo) | +£12-£18/mo | +£10-£16/mo | +£10-£16/mo | +£8-£14/mo |
| 5G access | Included | Included (10GB+) | Included (10GB+) | Included |
| Insurance (per device) | £5-£12/mo | £5-£11/mo | £5-£10/mo | £5-£10/mo |
| EU roaming | Add-on or included (higher tiers) | Included (10GB+) | Included | Included |
| Non-EU roaming | From £6/day | Included in 83 countries (10GB+) | From £6/day | From £5/day |
| Mid-contract price rise | CPI + 3.9% | CPI + 3.9% | CPI + 3.9% | CPI + 3.9% (some fixed plans available) |
All prices exclude VAT. Correct as of March 2026.
Hidden Costs to Watch
Mid-contract price rises are the most significant hidden cost in UK business mobile. Every major network applies annual increases linked to CPI (Consumer Price Index) plus a fixed percentage, currently 3.9% across the board. With CPI running at approximately 3-4% in early 2026, that translates to a 7-8% annual increase on your monthly bill. On a 24-month contract, your final monthly payment could be 8-16% higher than your initial price.
Out-of-bundle charges catch businesses off-guard. If a user exceeds their data allowance, charges of £3-£5 per additional GB apply on most networks. A single user streaming video or tethering without realising they have exceeded their limit can add £20-£50 to a single month's bill. Setting up data usage alerts and caps through your provider's business portal is essential.
Premium rate and international calls are not included in any standard business plan. Calls to 084, 087 and 09 numbers, as well as international calls, are charged at premium rates that vary significantly between networks. If your business regularly calls overseas, add an international calling bolt-on rather than paying per-minute rates.
Early termination fees apply if you need to cancel a contract before it ends. These are typically calculated as the remaining monthly payments for the contract term, which on a 24-month deal can amount to hundreds of pounds per line.

Multi-Line Discounts: How to Save 20-30%
One of the most effective ways to cut business mobile costs is simply to have more lines with one provider. Networks are aggressive about winning and retaining multi-line accounts, and the discounts available at scale are substantial.
Typical Multi-Line Discount Tiers
| Number of Lines | Typical Discount vs Single-Line Price |
|---|---|
| 2-4 lines | 5-10% |
| 5-9 lines | 10-15% |
| 10-19 lines | 15-22% |
| 20-49 lines | 20-28% |
| 50+ lines | 25-35% (negotiable) |
These discounts are not always published on network websites. They are most commonly available through authorised business partners (like Compare The Networks) who have negotiated preferential rates with each network.
Real-World Savings Example
A business with 10 lines on 25GB SIM only plans could expect to pay approximately:
- At standard single-line pricing: £14.00 x 10 = £140.00/mo (£1,680/year)
- With 10-line multi-line discount (approx. 18%): £11.50 x 10 = £115.00/mo (£1,380/year)
- Annual saving: £300.00 (ex. VAT)
At 20 lines, the saving doubles or more, because the per-line discount deepens as the number of connections increases. A 20-line account on the same plan might secure a 24% discount, saving over £800 per year.
Browse our dedicated pages for 5-line, 10-line and 20+ line business mobile deals for current multi-line pricing across all networks.
How to Maximise Your Discount
Consolidate all lines to one network. Split estates (lines across multiple providers) always cost more per line. Negotiate at renewal, networks offer the best deals to retain existing customers, especially at the 10+ line level. And always compare through an independent broker. Networks offer better pricing through partners than they do direct, because the cost of acquiring a customer through a broker is lower than through their own sales channel.
SIM Only vs Contract: Which Saves More?
This is one of the most common questions we hear. The answer depends on your circumstances, but in most cases, business SIM only deals save money over the full term.
24-Month Cost Comparison (per line, 25GB data, ex. VAT)
| Approach | Monthly Cost | 24-Month Total | Handset Cost | True 24-Month Cost |
|---|---|---|---|---|
| SIM Only + Buy Handset Outright | £14.00/mo | £336.00 | £400.00 (mid-range) | £736.00 |
| Contract (with handset) | £32.00/mo | £768.00 | £29.99 upfront | £797.99 |
In this typical example, buying a mid-range handset outright and pairing it with a SIM only plan saves approximately £62 per line over 24 months. Across 10 lines, that is a saving of £620.
When Contracts Make More Sense
SIM only is not always the better choice. If your business needs flagship devices (iPhone 16 Pro Max, Samsung Galaxy S26 Ultra) costing £1,000+, spreading the cost over a contract avoids a large upfront cash outlay. For businesses that want to refresh devices every two years without managing procurement, contracts provide convenience. Additionally, some networks offer exclusive multi-line pricing on bundled contracts that can close the gap.
When SIM Only Wins
SIM only plans are almost always cheaper if your team uses mid-range devices (£200-£500), if you already own usable handsets, if you want the freedom of shorter 12-month contracts, or if you want to avoid paying the implicit interest that handset contracts build into monthly pricing.
For most small and medium businesses, the sweet spot is SIM only plans on 12 or 24-month terms combined with purchasing devices separately, either outright or through a device leasing provider.

Frequently Asked Questions
1. What is the cheapest business mobile plan in the UK in 2026?
Three offers the cheapest business mobile plans in the UK as of 2026. Their SIM only plans start from £6.00 per month (ex. VAT) for 1GB of data with 5G included. For unlimited data, Three's £24.00 per month SIM only plan is the cheapest unlimited option from any major network. However, cheapest does not always mean best value, coverage, customer support and included extras also matter.
2. Do business mobile plans include VAT?
No. Business mobile plan prices are almost always quoted excluding VAT. You need to add 20% to the advertised price to calculate the actual cost. A plan advertised at £20.00 per month will cost £24.00 including VAT. If your business is VAT-registered, you can reclaim the VAT on business mobile costs, making the ex-VAT price the true cost to your business.
3. Can I keep my existing phone numbers when switching business mobile provider?
Yes. You have the legal right to port (transfer) your existing mobile numbers to any new provider. The process is managed through a PAC (Porting Authorisation Code), which your current provider must give you on request. Porting typically takes one working day. You can request a PAC by texting "PAC" to 65075 from any mobile, this works for both consumer and business lines.
4. What is a mid-contract price rise and can I avoid it?
A mid-contract price rise is an annual increase to your monthly bill, applied by the network during your contract term. All four major UK networks currently apply increases of CPI + 3.9% once per year, typically in March or April. With CPI at around 3-4%, that means a 7-8% increase each year. You cannot opt out on most plans, but some Three business plans offer fixed pricing for the duration of the contract, check the specific terms before signing.
5. Which network has the best 5G coverage for business?
EE has the best 5G coverage in the UK, reaching approximately 56% of the population across over 500 towns and cities. O2 is second at around 42%, followed by Vodafone at 38% and Three at 34%. However, 5G coverage is highly location-specific, a network with lower overall coverage might have excellent 5G in your particular area. Always check the coverage map for your specific locations.
6. Are there discounts for multiple business mobile lines?
Yes. Every major network offers multi-line discounts for business accounts. Discounts typically start at 5-10% for 2-4 lines and increase to 25-35% for 50+ lines. These discounts are often not published on network websites and are instead available through authorised partners. Compare The Networks can access preferential multi-line pricing across all networks. get a free quote to see your personalised pricing.
7. Can I mix different plans on one business mobile account?
Yes, on most networks. You can have different data allowances, contract lengths and even a mix of SIM only and handset contracts within a single business account. This is useful for businesses where different roles have different mobile requirements, field engineers might need unlimited data while office-based staff only need 10GB. O2 is particularly flexible here, allowing a mix of rolling monthly and fixed-term contracts on one account.
8. What happens when my business mobile contract ends?
When your contract ends, you move onto an out-of-contract or rolling monthly rate. Historically, this meant continuing to pay the same price (including the handset subsidy) even though your phone was paid off. O2's Refresh scheme automatically reduces your bill when the handset element is paid. On other networks, it is essential to contact your provider at the end of your contract to negotiate a new deal or switch to a SIM only plan.
9. Is it better to go direct to the network or use a comparison service?
In most cases, using an independent comparison service or authorised partner delivers better pricing than going direct. Networks offer brokers preferential rates because the customer acquisition cost is lower. An OFCOM-regulated comparison service like Compare The Networks also provides impartial advice across all networks rather than the single-network bias you get from going direct. We are not incentivised to recommend one network over another.
10. How long does it take to set up a new business mobile account?
A new business mobile account can typically be activated within 1-3 working days. SIM only plans are usually the fastest, once approved, SIMs are dispatched and can be active within 24 hours. Handset contracts may take 2-3 days due to device dispatch. Porting existing numbers takes one additional working day. For larger accounts (20+ lines), allow up to five working days for full setup and number porting.

Their SIM only plans start from £6.00 per month (ex. VAT) for 1GB of data with 5G included. For unlimited data, Three's £24.00 per month SIM only plan is the cheapest unlimited option from any major network." } }, { "@type": "Question", "name": "Do business mobile plans include VAT?", "acceptedAnswer": { "@type": "Answer", "text": "No. Business mobile plan prices are almost always quoted excluding VAT. You need to add 20% to the advertised price to calculate the actual cost. A plan advertised at £20.00 per month will cost £24.00 including VAT. If your business is VAT-registered, you can reclaim the VAT on business mobile costs." } }, { "@type": "Question", "name": "Can I keep my existing phone numbers when switching business mobile provider?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. You have the legal right to port your existing mobile numbers to any new provider. The process is managed through a PAC (Porting Authorisation Code), which your current provider must give you on request. Porting typically takes one working day. You can request a PAC by texting PAC to 65075 from any mobile." } }, { "@type": "Question", "name": "What is a mid-contract price rise and can I avoid it?", "acceptedAnswer": { "@type": "Answer", "text": "A mid-contract price rise is an annual increase to your monthly bill, applied by the network during your contract term. All four major UK networks currently apply increases of CPI + 3.9% once per year. With CPI at around 3-4%, that means a 7-8% increase each year. You cannot opt out on most plans, but some Three business plans offer fixed pricing for the duration of the contract." } }, { "@type": "Question", "name": "Which network has the best 5G coverage for business?", "acceptedAnswer": { "@type": "Answer", "text": "EE has the best 5G coverage in the UK, reaching approximately 56% of the population across over 500 towns and cities. O2 is second at around 42%, followed by Vodafone at 38% and Three at 34%. However, 5G coverage is highly location-specific, so always check the coverage map for your specific locations." } }, { "@type": "Question", "name": "Are there discounts for multiple business mobile lines?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. Every major network offers multi-line discounts for business accounts. Discounts typically start at 5-10% for 2-4 lines and increase to 25-35% for 50+ lines. These discounts are often not published on network websites and are instead available through authorised partners like Compare The Networks." } }, { "@type": "Question", "name": "Can I mix different plans on one business mobile account?", "acceptedAnswer": { "@type": "Answer", "text": "Yes, on most networks. You can have different data allowances, contract lengths and even a mix of SIM only and handset contracts within a single business account. O2 is particularly flexible here, allowing a mix of rolling monthly and fixed-term contracts on one account." } }, { "@type": "Question", "name": "What happens when my business mobile contract ends?", "acceptedAnswer": { "@type": "Answer", "text": "When your contract ends, you move onto an out-of-contract or rolling monthly rate. O2's Refresh scheme automatically reduces your bill when the handset element is paid. On other networks, it is essential to contact your provider at the end of your contract to negotiate a new deal or switch to a SIM only plan." } }, { "@type": "Question", "name": "Is it better to go direct to the network or use a comparison service?", "acceptedAnswer": { "@type": "Answer", "text": "In most cases, using an independent comparison service or authorised partner delivers better pricing than going direct. Networks offer brokers preferential rates because the customer acquisition cost is lower. An OFCOM-regulated comparison service like Compare The Networks also provides impartial advice across all networks." } }, { "@type": "Question", "name": "How long does it take to set up a new business mobile account?", "acceptedAnswer": { "@type": "Answer", "text": "A new business mobile account can typically be activated within 1-3 working days. SIM only plans are usually the fastest, active within 24 hours. Handset contracts may take 2-3 days due to device dispatch. For larger accounts of 20 or more lines, allow up to five working days for full setup and number porting." } } ] } </script>
