"How much does business mobile cost?" deserves a straight answer, and most of the industry refuses to give one - every price is "from", every quote needs a meeting. So here is the CFO's version: real indicative ranges for what UK businesses pay in mid-2026, what pushes a bill up or down, the hidden costs that never appear on the headline quote, and two worked example bills you can benchmark your own against. One honest caveat before we start: every figure here is an illustrative guide as of June 2026, not a quote. Business mobile pricing moves constantly and depends on network, line count, data shape and negotiation - which is the whole reason we price each business individually.
The headline ranges: per line, per month
All figures ex VAT, illustrative, June 2026. Business pricing is conventionally quoted ex VAT - remember that when comparing against consumer deals, which include it.
SIM-only (airtime only)
| Data tier | Typical per line, per month | Notes |
|---|---|---|
| Low data (~5GB) | ~£5-£8 | Desk-based staff on Wi-Fi all day |
| Mid data (~25GB) | ~£7-£12 | The mainstream business tier |
| High data (~100GB) | ~£10-£16 | Field and mobile-first staff |
| Unlimited | ~£15-£25+ | Tethering, heavy use, 5G backup |
| Pooled/shared | Varies with pool size | Usually the best per-GB value from ~5 lines |
Unlimited UK calls and texts are standard across business tariffs in 2026 - data is the variable you are really buying. For the detail on what these plans include, see our business SIM-only guide.
With a handset bundled
A bundled contract is airtime plus a phone paid off over the term (usually 24-36 months), and the financing is rarely free:
| Setup | Typical per line, per month | Notes |
|---|---|---|
| SIM + budget/mid-range handset | ~£25-£40 | Sensible default for most staff |
| SIM + flagship handset | ~£40-£60+ | The flagship is the cost, not the airtime |
| Handset bought outright + SIM-only | airtime + one-off cost | Usually the cheapest total over the device's life |
The pattern to internalise: airtime is cheap; hardware is what makes mobile expensive. A £900 flagship spread over 36 months adds £25+ a month before any interest or mark-up - which is why the SIM-only vs handset decision moves bills more than any network choice.
What drives the price up or down
Up:
- Data tier and shape - unlimited everywhere when usage does not justify it is the most common overspend.
- Handset financing - flagships on 36-month bundles, refreshed every cycle.
- Short terms - 30-day and 12-month flexibility carries a premium.
- Roaming - daily roaming charges across travelling staff compound quickly.
- Out-of-contract drift - lines past their term, paying full rates with no negotiated discount.
Down:
- Line count - per-line rates fall meaningfully as connections grow; 20 lines price better than 5.
- Pooled data - one right-sized bucket instead of per-line guesses; see how pooling works.
- Longer terms - 24 months prices better than 12; 36 better still, with the flexibility trade-offs covered in our contracts guide.
- Keeping handsets longer - stretching a device from 24 to 40+ months is one of the cleanest savings in telecoms.
- Negotiation and comparison - business mobile is a negotiated market; the rate card is the starting point, not the price.
The hidden costs that never make the quote
When I benchmark a business's real spend against what they thought they were paying, the gap almost always lives here:
- Roaming. EU roaming varies by network and plan - included on some tiers, a daily charge on others - and rest-of-world rates can be punishing. A team with three regular travellers can quietly add three figures a month.
- Out-of-bundle usage. Premium-rate numbers, directory enquiries, international calls from the UK, picture messages. Individually small, collectively persistent. Spend caps cost nothing and stop the bleeding.
- Insurance and replacement. Device insurance typically runs a few pounds per device per month - rational for field staff, often redundant for desk dwellers. Decide deliberately rather than ticking the box estate-wide.
- MDM and security. Mobile device management licences typically add a few pounds per device per month. Unlike most items on this list, this one is worth paying - see what MDM is and why it matters.
- Accessories and the drawer of doom. Cases, chargers, the spare handsets nobody tracks. Small numbers that round up over a year.
- Early termination and upgrade fees. Leaving or changing mid-term has a price; know it before you sign, not after.
Worked example: a 5-person company
A trades firm - two in the office, three on the road. Bought sensibly: SIM-only, existing handsets where decent, pooled data. Illustrative June 2026 figures, ex VAT:
| Item | Monthly |
|---|---|
| 5 x business SIMs, unlimited calls/texts, pooled data (~60GB) | ~£40-£60 |
| MDM on 5 devices | ~£10-£15 |
| Insurance on 3 field handsets | ~£15-£25 |
| Total | ~£65-£100 |
The same firm buying lazily - five unlimited lines, two flagships on 36-month bundles, insurance on everything - lands closer to £150-£200 a month for no extra capability. Same company, same phones in pockets; the difference is purely how it was bought.
Worked example: a 20-person company
A professional services firm - fourteen office-based staff, six managers and field staff with company handsets. Mixed estate, pooled data:
| Item | Monthly |
|---|---|
| 20 x business SIMs with pooled data (~250GB) | ~£140-£220 |
| 6 x mid-range handsets spread over 24-36 months | ~£90-£150 |
| MDM across 20 devices | ~£40-£60 |
| Insurance on 6 company handsets | ~£30-£50 |
| Roaming add-ons, 2 regular travellers | ~£10-£30 |
| Total | ~£310-£510 |
Per line, that is roughly £15-£25 all-in - a useful benchmark. Estates we review that sit north of £30-£35 per line almost always contain at least one of: flagship bundles by default, unlimited data nobody uses, drifted out-of-contract lines, or insurance applied indiscriminately.
How to benchmark your current bill
Fifteen minutes with your last invoice:
- Total monthly cost ÷ number of lines. Compare against the tables above. Under ~£15 per line all-in is well-bought; £20-£30 deserves a look at the mix; £30+ usually means money on the table.
- Data bought vs data used. Most portals show per-line usage. If the estate uses a third of what it buys, you are paying for the gap.
- Find the drifters. Any line past its contract end date is almost certainly overpriced - and any line for someone who left is pure waste. (It happens more than you would think.)
- Check the small print lines. Roaming, out-of-bundle, premium services, insurance - the items that grew without a decision.
- Check your renewal date. If it is within three months, you are in the window where comparing the market has maximum leverage - our cost-saving guide covers what to do with it.
Or skip the spreadsheet: send us your headcount and rough usage and we will benchmark your bill against current EE, Vodafone and O2 business pricing for free.
Does the network change the price?
Less than you might expect. EE typically prices at a premium consistent with its performance lead; Vodafone and O2 compete harder on multi-line business deals; and since the Vodafone-Three merger, Vodafone has been pushing hard for business market share, which keeps pricing competitive. But the spread between networks for a comparable plan is usually smaller than the spread between a well-bought and badly-bought estate on the same network. Choose the network on coverage at your postcodes - our network comparison covers that decision - and fix the buying first.
The bottom line
In 2026, well-bought business mobile costs roughly £5-£25 per line per month for airtime depending on data, with handsets, MDM and insurance added deliberately on top - landing most sensible estates at £15-£25 per line all-in. Badly-bought mobile costs half as much again, for nothing extra. The difference is not the network or some secret tariff; it is right-sized pooled data, SIM-only by default, handsets kept longer, and a renewal calendar.

Frequently asked questions
How much does business mobile cost per month in the UK?
As an illustrative mid-2026 guide: around £5-£25+ per line per month ex VAT for SIM-only depending on data tier, and roughly £25-£60+ per line when a handset is bundled. Well-run estates typically land at £15-£25 per line all-in once MDM and extras are included.
How much does a business mobile contract cost for a small business?
A sensibly-bought 5-person setup typically runs around £65-£100 a month ex VAT including pooled data, MDM and selective insurance - and roughly £150-£200 if bought lazily with flagship bundles and unlimited everything. See our worked examples for where the money goes.
Why are business mobile prices quoted ex VAT?
Business pricing is conventionally quoted excluding VAT because VAT-registered businesses reclaim it. When comparing against consumer deals, remember consumer prices include VAT - a £10 consumer SIM and a £10 ex-VAT business SIM are not the same price.
What hidden costs should I watch for on business mobile?
Roaming charges, out-of-bundle usage (premium numbers, international calls), device insurance applied indiscriminately, MDM licences, accessories and early termination fees. Most bill shock comes from these lines rather than the headline tariff - spend caps and usage alerts catch most of it.
Is unlimited data worth it for business?
Only for genuinely heavy users - tethering, field video, mobile-first roles. Most office-based staff use a few gigabytes a month on top of Wi-Fi. For teams of five or more, a pooled allowance sized on real usage usually delivers the same practical outcome for less.
Does it cost more to buy business mobile through a reseller?
No - resellers are paid by the networks, and partner pricing is often as good as or better than direct rates for SMEs. The value is in the comparison across networks and the account management; see our guide to business mobile providers.
How do I know if my business is overpaying for mobile?
Divide your total monthly mobile spend by your number of lines. Under about £15 all-in is well-bought; over £30 usually signals flagship bundles by default, unused data, drifted out-of-contract lines or blanket insurance. Benchmarking against current market pricing at renewal time settles it definitively.
