What you actually buy

A business mobile estate is not one product. You are choosing a mix of airtime, handsets and how data is shared — and the mix moves the bill more than the network logo on the invoice. Most UK teams buy one of three things, or a combination of them.

What you buyWhat it isWhen it usually fits
SIM-only Airtime on a phone you already have, or buy outright. Desk and hybrid staff; anyone whose handset still works.
Handset contract Airtime plus a phone paid off over 24–36 months. When you need new devices and want one bill.
Pooled data One shared data bucket across the lines, not a guess per person. Teams of about five or more with mixed usage.

Unlimited UK calls and texts are standard on business tariffs in 2026. Data is the variable you are really buying, and hardware is what makes a line expensive. The decision between SIM-only and a handset contract is covered in full there; current SIM-only deals and how data pooling stops one heavy user causing bill shock are separate guides. This page will not restate them.

The fourth thing most estates need is not a tariff at all: mobile device management, so a lost phone can be locked and wiped and company email does not live on an unmanaged handset. MDM is typically a few pounds per device per month. It is worth paying; it is not worth inventing a price for here. A quote will ask how many devices need it rather than ticking it on for everyone by default.

What it costs

Every figure below is an illustrative August 2026 guide, ex VAT — typically what UK businesses pay, not a tariff we are selling and not a quote. Business mobile pricing moves with network, line count, data shape and negotiation. The ranges are the ones already published in our business mobile cost guide.

As a guide: SIM-only typically £5–£25 per line per month; a handset bundle typically £25–£60+ per line. Well-bought estates usually land at £15–£25 per line all-in once MDM and extras are included.

SetupTypical per line / monthNotes
SIM-only, low data (~5 GB) ~£5–£8 Desk-based staff on Wi-Fi all day
SIM-only, mid data (~25 GB) ~£7–£12 The mainstream business tier
SIM-only, high data (~100 GB) ~£10–£16 Field and mobile-first staff
SIM-only, unlimited ~£15–£25+ Tethering, heavy use, 5G backup
SIM + budget or mid-range handset ~£25–£40 Sensible default when a new phone is needed
SIM + flagship handset ~£40–£60+ The flagship is the cost, not the airtime

A worked 5-person trades firm, bought sensibly — SIM-only, existing handsets, pooled data — typically lands around £65–£100 a month ex VAT including MDM and insurance on the field phones. The same firm buying lazily with flagship bundles and unlimited everything is closer to £150–£200 for no extra capability. A 20-person mixed estate is typically £15–£25 per line all-in. If you are paying much over £30 per line, you are probably overpaying. The cost guide has the worked bills; this page will not invent a fourth set of numbers.

The gap between the headline tariff and the real bill is almost always roaming, out-of-bundle usage, insurance applied to every desk phone, and lines that drifted past their term. Since January 2025, any mid-contract rise on a new deal has to be written in pounds and pence before you sign — include year-two and year-three when you compare. We will do that on a quote. The cost guide is the place for the hidden-cost list and the two worked examples; cutting the bill is the place for what to do at renewal.

EE, Vodafone or O2

There is no “best network” for every team. The right answer is signal at your office, sites and home-working addresses, plus the support and tooling you actually use. National league tables are the starting point, not the decision. Our network comparison and coverage guide go through that properly; the head-to-heads — EE vs Vodafone, O2 vs Vodafone, EE vs O2 — sit there too.

What to weighEEVodafoneO2
Coverage Strong rural footprint; leading 5G build. Combined Vodafone + Three signal as integration rolls out. Rated highly for overall coverage experience.
Speed and reliability Leads independent testing, consistently. Improving with the merged network; ask about your postcodes today. Historically trailed on speed; recent results are closing the gap.
Business tooling Solid business plans; usually premium-priced. Fleet tools, roaming and larger-estate pedigree. Flexible terms; bundling with Virgin Media connectivity.
Sensible starting point Teams that depend on mobile data. Multi-site, travellers, larger fleets. Coverage-first teams who want flexibility.

Three is no longer sold to new business customers — Vodafone is the business brand of the merged VodafoneThree operator. If you are already on Three business, review before you are migrated by default. Per-network plan notes live on the EE, Vodafone and O2 guides. We will not pick a winner on this page.

Direct vs a reseller

You can buy business mobiles straight from EE, Vodafone or O2. You can also buy through someone who holds partner agreements with more than one of them. We are the second kind. The networks pay us; you do not pay a broker fee on top, and partner pricing for SMEs is often as good as or better than the rate card you would be offered direct.

The useful difference is the comparison. A network shop will sell you that network. We will put the same estate on EE, Vodafone and O2 and show you the spread — coverage at your postcodes, pooled data, MDM, contract length and the mid-term rises stated in pounds and pence. That is the job described in our guide to business mobile providers: who to buy from, and when going direct still makes sense. Going direct is still rational if you already have a named account manager you trust, or you are a large enough estate to negotiate your own tariff. For most SMEs the bottleneck is not access to a network; it is being shown more than one. If you already know the network and only want fulfilment, say so on the quote and we will not pretend otherwise.

How a quote works

There is no second form on this page and nothing to “request a callback” into a void. The quote is a five-step wizard on the quote page: how many handsets or SIMs, when the current contracts end, business type, a name and postcode, then how to reach you. Sole traders are fine; a personal email is accepted. We do not ask for a current network up front — that is our job to compare, not yours to declare.

  1. You tell us the estate. Headcount, roughly how the phones are used, where people work, and when you are free to move. A recent bill helps but is not required.
  2. We compare the networks. The same brief goes across EE, Vodafone and O2. We check coverage at the postcodes that matter and size SIM-only, handsets and pooled data against how you actually work.
  3. You get a proposal. A named advisor sends a written comparison. No obligation. If waiting for a renewal window is cheaper than moving now, we will say that.

Contracts, switching and sole traders

Business mobile contracts are typically 24 or 36 months; 12-month and rolling terms exist and usually cost more. Notice periods and early-termination charges are the bits that catch people, not the headline term. Cheap contracts are a real category — they are cheap because something has been stripped, not because we found a secret tariff. Small teams have their own shape; the small-business plans guide is the place for that, not this page.

Switching is less dramatic than it sounds. Numbers move with you. The sweet spot for comparing the market is about three months before renewal, which is when switching provider has the most leverage and the least wasted notice. We will time a quote around that if you tell us the end date. For a handful of lines the port is usually one planned morning; for a fleet we stagger it. The contract-length guide is the place for 12 vs 24 vs 36 months, not a recap here.

Sole traders are eligible. You do not need a limited company. The networks want evidence you are trading, and the quote form is built for it. Whether a business plan beats a consumer SIM for one or two lines is a genuine question — our sole trader guide answers it without pretending every freelancer needs a fleet tariff.

Handsets

We are not a phone shop. If the devices you have will last the term, buy airtime and stop there. When a new handset is actually needed, the existing guides cover the ground: the best business phones for 2026, iPhone and Samsung picks, Android vs iPhone, plus rugged, refurbished and budget options, and whether to lease or buy. On a quote we will ask how many new phones you need — not push a flagship onto every desk.

Sectors we work with

The same three networks, bought differently. Construction is the sector we are asked about most; the dedicated guide owns that term, and this page will not compete with it. The others have their own notes on coverage, rugged kit, shift patterns and who pays the bill.

Frequently asked questions

How much do business mobiles cost in the UK?

As an illustrative August 2026 guide, SIM-only typically runs from around £5 to £25 per line per month ex VAT depending on data, and a handset bundle is typically £25 to £60+ per line. Well-bought estates usually land at £15 to £25 per line all-in once MDM and extras are included. These are guide figures, not a quote — we price each team against current EE, Vodafone and O2 business rates.

Can a sole trader get a business mobile contract?

Yes. Sole traders are eligible. You will need to show the network you are trading — typically a business bank account, UTR or similar — and the quote form accepts a personal email. A consumer SIM can still be rational for one line; a business plan is worth it once you want a proper invoice, VAT recovery or room to add lines later.

Can we keep our existing numbers if we switch?

Yes. Number porting is a regulated right. You request a PAC (or a STAC if you are not keeping the numbers) and the gaining provider moves them, typically within one working day per batch. We project-manage porting for the whole estate so it does not land on your Friday afternoon.

Should we buy SIM-only or a handset contract?

SIM-only is usually cheaper if the phones you have are still serviceable. A handset contract makes sense when you need new devices and want one bill. Airtime is the cheap part; hardware is what makes a line expensive. Most mixed teams end up with both — SIM-only for desk staff, a bundled handset only where a new phone is actually needed.

Which network is best for business mobiles — EE, Vodafone or O2?

There is no single winner. EE leads independent speed and reliability testing and suits teams that depend on mobile data. Vodafone is the business brand of the merged VodafoneThree network and is often the strongest fit for larger fleets and international roaming. O2 rates highly for overall coverage experience and flexible terms. Check signal at your actual postcodes before you sign.

How long does it take to switch business mobiles?

For a small team, a switch can complete in a few working days once the proposal is agreed — SIMs or eSIMs first, numbers ported on a planned morning. Larger fleets are staggered so a snag affects a handful of people, not everyone at once. The longest lead is usually notice on the current contract, not the port itself.

Do business mobile contracts still have mid-contract price rises?

They can, but since January 2025 Ofcom has required any in-contract increase on a new contract to be stated in pounds and pence upfront. The old inflation-linked CPI + 3.9% clauses are banned on new deals. Ask for year-two and year-three pricing in writing and include it when you compare quotes.

What happens after I submit a quote?

One of the Geeks — a named advisor, not a call centre — reviews what you sent and comes back with a comparison across EE, Vodafone and O2 for your headcount, postcodes and contract timing. There is no obligation and no second form. If the timing is wrong we will say so.
