In short
Business Telco is a business SIM-only provider with access to all four UK networks — O2, EE, Vodafone and Three.

Who business SIM-only suits
Business SIM-only works best when your team already has handsets and you want to compare ongoing costs or move away from an expensive bundled deal. You keep your numbers, choose the allowances you actually need, and avoid paying for hardware you don't.

Weighing the trade-offs between plans? Our compare business SIM-only deals guide walks through coverage, allowance fit, roaming, excess charges, contract length and support. For the wider picture — plan types and how to choose a tariff — see the business mobile plans UK guide.
Fixed monthly rental means fewer surprises
When comparing business mobile plans, it is worth looking beyond data allowances and headline price. Your agreed monthly rental with Business Telco stays fixed for the full contract term, giving your business better cost certainty with no mid-contract rental increases. Usage, roaming and other additional charges can vary.
All four networks
O2, EE, Vodafone and Three — through one provider
There is no single best network for every business — the right choice depends on coverage at your sites, your data needs and how your team works. Because we work with all four, we recommend the network that fits rather than one we're tied to. Explore each from a business perspective below, or see which network is best for business.
Business SIM only vs business data SIM
Business SIM only plans are usually aimed at everyday phone users, while business data SIMs are more relevant for routers, tablets and connected devices. Some businesses need one, some need both.
One network or more than one?
For some businesses, putting everyone on one network is simple but not ideal. A mixed-network setup can make more sense where coverage varies across sites, depots or user types.
If your team uses newer devices, you may also want to consider business eSIM as an alternative to physical SIM cards for faster provisioning and device flexibility. For a deeper look at tariff comparison, see compare business SIM-only deals. Not sure whether you need voice SIMs or data-only SIMs? Our SIM only vs data SIM guide explains the difference. You can also explore which network is best for business.
Frequently asked questions
Can I ask about a single connection or a team?
Yes. Choose your connection band in the quote form, including one connection or not sure. Suitability and any eligibility requirements are confirmed before you order.
Can I keep my existing numbers?
Tell us which numbers you want to keep and your current contract end dates. The proposal can confirm transfer requirements and any applicable terms before arrangements are agreed.
Can different colleagues use different networks?
Include the locations and preferences involved in your enquiry. A mixed-network setup does not mean a single SIM automatically switches networks; billing arrangements are confirmed in the proposal.
When should I enquire about a renewal or new connection?
Use the start or renewal timing field. Tell us whether you need new connections, are switching or are reviewing a renewal. We will confirm available start dates as part of your proposal.
Does fixed rental mean my bill can never change?
No. The agreed monthly rental stays fixed for the contract term, but usage, roaming and other additional charges can vary. Check the proposal for the charges and billing arrangements that apply.
Is roaming included?
Give us the destinations and travel requirements so we can confirm the right terms. The displayed voice and data allowances do not establish roaming inclusions.
Not sure which network suits your business best?
