What's the real total cost of ownership?
If you already own your phones, SIM-only is cheapest. If you need new handsets, spreading them over the contract is usually the lowest total cost of ownership. Here’s how the two compare over a 36-month term.
 SIM-only |
 Budget phoneincluded |
 Mid-range phoneincluded |
|
|---|---|---|---|
| Includes a phone | Use your own phone | Yes | Yes |
| Per month | from £5.80 | from £13 | from £24 |
| Over 36 months | from £209 | from £468 | from £864 |
| You own the phone | Yes (already yours) | Yes, at end of term | Yes, at end of term |
A phone on contract spreads the handset cost across the term rather than paying upfront – figures here are over 36 months; a 24-month term costs a little more each month. Data allowances vary by plan; “from” prices exclude VAT. See the VAT question in our FAQs below.

Business mobile plan calculator FAQs
What is the cheapest business mobile plan in the UK?
The cheapest business mobile plans are SIM-only, from £5.80 a month per user. Exact prices vary by network and data size – for example, a 5GB O2 business SIM is around £7.50 a month and a 30GB O2 SIM around £11. Unlimited data starts from about £20. All available across EE, O2, Vodafone and Three.
Which business SIM-only deals are cheapest?
Prices vary by network and data allowance rather than being fixed across all four. As a guide, current examples include a 5GB O2 SIM around £7.50, a 10GB EE SIM from about £10, a 30GB O2 SIM around £11 and a 100GB O2 SIM around £13 a month per user. See our SIM-only page for the latest across every network.
What do unlimited-data business plans cost?
Unlimited-data business SIMs start from around £20 per user a month, depending on network and term. For most teams we recommend right-sizing data rather than defaulting to unlimited, which usually saves money.
What's the cheapest business phone with a contract?
The cheapest business phone with a contract is the Samsung Galaxy A16, from £14 a month. The cheapest option for each brand is the Motorola Moto G56 5G from £14, the Google Pixel 9a from £21, and Apple’s iPhone 16e from £24. Final prices depend on the network, data and contract length.
SIM-only vs handset-inclusive: what's the real total cost of ownership?
If you already own your phones, SIM-only is cheapest – from £5.80 a month, about £209 over 36 months. If you need handsets, a phone on contract spreads the cost across the term: a budget phone like the Galaxy A16 is from £14 a month, with no upfront cost. We’ll confirm the exact numbers for your chosen device on the call.
Which network is best for business mobile in the UK?
It depends where your team works. EE has the widest 4G and best rural signal; O2 is strong in urban areas with reliable roaming; Vodafone is popular for international travel; Three offers the most competitive pricing and unlimited data. Business SIM-only starts from £5.80/mo across all four, and we can mix networks across your team.
Can I mix networks and tariffs across my team?
Yes. BusinessMobiles.com works across all four major UK networks – EE, O2, Vodafone and Three – so you can match each person to the right network and tariff, with a single view across the whole team.
What if my team would rather share one pool of data?
If your team’s data use varies month to month, a shared data plan can work out cheaper than a fixed allowance each. Our Smart Spend data pooling plans put your whole team on one shared pool, reviewed every quarter, so you only pay for what you actually use.
Can I keep my existing numbers when I switch?
Yes. Request a PAC code from your current provider and porting usually completes within one working day. Your consultant manages the whole switch to avoid any disruption.
How do VAT and capital allowances work on business mobiles?
Usually in your favour. If your business is VAT-registered you can normally reclaim the VAT on the business-use portion of your mobile costs, and the monthly cost is an allowable business expense that reduces your taxable profit. How the handset is treated depends on whether you buy it outright or take it on contract.
- VAT: reclaimable on the business-use proportion if you’re VAT-registered; where phones are also used personally, only the business share counts.
- Airtime & SIM-only: the monthly cost is normally a deductible operating expense.
- Handsets: a phone bought outright may qualify for capital allowances, often within the Annual Investment Allowance; a phone on contract is usually expensed over the term.
This is general guidance, not tax advice – rules and thresholds change, so check your specific position with your accountant or HMRC.
