In short
We supply business SIM only plans on EE Business and Three Business, and we can also supply O2 Business and Vodafone Business. Each has its own plan types, account controls and switching process. The most useful way to choose is coverage where your team works, checked on each network's own coverage checker, then plan structure and contract terms.

The networks we supply
Every business SIM only plan runs on one of the UK's mobile networks. We supply business SIM only plans on EE Business and Three Business, and we can also supply O2 Business and Vodafone Business. Each network page explains what that network publishes about its business SIM only range and how we can help you use it.
EE Business sells SIM only plans for businesses with 1-10 employees and separate plans for businesses with 11 or more employees. The larger range has three plan types (The Team Plan, The Shared Plan and The Individual Plan), and the account tools include spend caps, Bill Protector options and the Mobile Manager portal. See EE Business SIM only plans.
Three Business SIM Only plans run on 1, 12 or 24-month terms, with data from 3GB up to unlimited (unlimited usage is UK only, with fair use policies in Go Roam destinations). Three Business also has data only SIMs, Multibuy SIM plans for teams and eSIM on every plan. See Three Business SIM only.
O2 Business lists SIM only plans in its online shop on 12 or 24-month terms, with data options up to unlimited and spend caps. We can also supply SIM only plans on the O2 Business network, with the plan and terms confirmed at quote. See O2 Business SIM only plans.
Vodafone Business has ranges for small businesses (1-9 employees) and for medium and large businesses, and lists SIM only plans on terms including 30 days, 12 months and 24 months. We can supply SIM only plans on the Vodafone Business network, again with the terms confirmed at quote. See Vodafone Business SIM only.
We describe each network on its own terms. Which one suits you depends on where your people work and how they use their phones, and we help you work that out for your business.
Start with coverage where your people work
Coverage is the one thing a good price cannot fix. A plan that looks right on paper is no use if your warehouse, your customers' sites or your sales team's regular routes have weak signal on that network.
Each network publishes its own coverage checker, and the sensible way to use them is to check the places that matter to you rather than the national picture:
- List your locations: offices, warehouses, shops, depots, customer sites and the postcodes of staff who work from home
- Add the routes: the roads and rail lines your mobile staff use every week
- Check each network's coverage checker: look at indoor and outdoor coverage, and at 5G where you plan to use it
- Ask your team: people already know where their current phones struggle, which tells you what to look for
- Weigh the gaps: decide which locations are essential and which can rely on WiFi calling or a fixed line
If your current network works well for you, staying on it and moving to a business SIM only plan may be the simplest win. If it does not, coverage tells you where to look next. Either way, we can help you work through the list before you commit to a term.
What else to weigh up
Once coverage has narrowed the field, the plan itself matters. These questions apply on every network, and the answers are confirmed at quote:
| What to check | Question to ask | Where to read more |
|---|---|---|
| SIM types | Do we need voice SIMs, data-only SIMs, eSIMs or IoT SIMs, or a mix? | Business data only SIM, eSIM SIM only |
| Data structure | Should each person have their own allowance, or should the team share data? | Business SIM only plans |
| Data size | Do some lines need unlimited UK data, and what fair use terms apply? | Unlimited data business SIM |
| Contract length | 24 months, 12 months or a rolling monthly plan, and how do annual price rises work? | Business SIM only contracts |
| Account controls | Can we set spend caps and roaming caps, and manage lines online? | Fleet SIM cards |
| Roaming | Which staff travel, and how is roaming priced and capped on each line? | Unlimited data business SIM |
| Switching | How will numbers move, and on what date? | Keep your number |
Prices depend on the number of lines, the data and the term, so ask us for a quote and we can set out the options that fit your business.

5G and eSIM on every network
Every network we supply offers eSIM on business plans for compatible devices, and 5G where a line has a 5G-capable device and 5G coverage where that person works. Both make SIM only easier to run: eSIM means a new starter can be set up without posting a card, and 5G gives heavy data users more headroom where it is available.
If 5G matters to you, our guide to 5G SIM only for business explains what you need: a 5G-capable device, 5G coverage where you work and a plan that includes it. For eSIM, see eSIM SIM only, which also covers pairing eSIM with device management.
One network or more than one?
Most businesses keep all their lines on one network. One account means one bill, one set of controls and one place to add or remove users, which is the main reason organisations manage their fleet SIMs together.
There are good reasons to split, though:
- A site with a coverage gap: a depot or shop where another network has the stronger signal
- Data SIMs for equipment: routers or tablets at one location placed on whichever network works there
- Backup connectivity: a data SIM on a different network from your main lines, for resilience
- Devices that roam between networks: some IoT SIMs can attach to more than one network; see what is a multi SIM
Each network keeps its own account, contract and billing. We can quote across the networks we supply and help you keep track of which SIM sits on which account.
Need help choosing?
We will recommend what fits your organisation and explain why, in plain English.
Changing network and keeping your numbers
Changing network does not mean changing numbers. Under Ofcom's switching rules you text PAC to 65075 from the number you want to keep (if there is more than one number on the account, you ask your provider by phone or on its website), give the PAC to your new provider, and the new provider must complete the switch within one working day. A PAC is valid for 30 days. If you want a new number instead, you text STAC to 75075.
Our keep your number guide explains the process in full, including PAC codes and how to port multiple mobile numbers for a whole team.
Your phones only need to change if they are locked to your current network. Unlocked phones work on any network, so moving to SIM only on a new network is often just a SIM swap or a new eSIM.
How we help
Working with one supplier across EE Business, Three Business, O2 Business and Vodafone Business means you can weigh them up in one conversation instead of four. We can:
- Check coverage with you: work through your locations on each network's coverage checker
- Match plan types to your team: voice SIMs, data SIMs, eSIM and IoT SIMs, individual or shared data
- Quote the networks that fit: with the plan and contract terms set out clearly
- Plan the switch: PAC and STAC codes, switch dates and SIM or eSIM activation
- Keep records straight: which SIM is on which network, account and device

Frequently asked questions
Which networks can you supply business SIM only plans on?
We supply business SIM only plans on EE Business and Three Business, and we can also supply O2 Business and Vodafone Business. Plans and terms for your lines are confirmed at quote.
How do I choose a network for business SIM only?
Start with coverage where your people work: offices, sites, routes and home postcodes, checked on each network's own coverage checker. Then compare the plan structure, contract length and account controls that suit your team.
Do you supply Three Business SIM only plans?
Yes. We supply Three Business SIM Only plans on 1, 12 or 24-month terms, data only SIMs and eSIM on every plan. The plan, term and price for your lines are confirmed at quote.
Can I keep my numbers if I change network?
Yes. Text PAC to 65075 from the number you want to keep, or ask your current provider by phone or on its website if there are several numbers on the account, then give the codes to your new provider. Under Ofcom's rules the new provider must complete the switch within one working day.
Do I need new phones to change network?
Not if your phones are unlocked. A SIM only plan works in any compatible unlocked phone, so changing network usually means a new SIM or eSIM. Locked phones need unlocking by the current network first.
Can my business use more than one network?
Yes. Some businesses put a site or a group of data SIMs on a different network for coverage or backup. Each network keeps its own account and contract, and we can help you manage the split.
