Cader NetworksBusiness SIM-only contracts for staff, devices and equipment
SIM-only plans for company phones and staff mobiles, data SIMs for tablets and routers, multi-network SIMs where coverage is critical, and specialist SIMs for fitted equipment — through EE, O2, Vodafone and multi-network partners, matched to what you actually need.
One team for your SIMs, not a call centre queue
Buying business mobile direct means picking one network and living with it. We supply and manage business SIMs across multiple providers, so the starting point is your team and your locations, not a single network's price list.
- Independent guidance — we help pick the network and plan that fits, not just the one we happen to sell
- Single-network or multi-network — we help you choose which one your use case actually needs
- Porting and activation handled for you, whether it's 2 numbers or 200
- One point of contact for SIMs alongside broadband, VoIP and leased lines
- Real support from a Welsh-based team who know your account
How it works
- Tell us what you need — how many SIMs, what they're for
- We review suitable options across networks
- We arrange the SIMs and activation
- Ongoing business support from our team
Four kinds of business SIM, matched to the job
Standard business SIM-only contracts
The default option for most teams. Use your own unlocked handset or an existing device — no handset tie-in. Available on single-network plans through EE, O2 or Vodafone, subject to the selected tariff, with number porting handled for existing business numbers in most cases.
Business data SIMs
Data-only SIMs for devices that don't need calls or texts — tablets, laptop dongles and 4G/5G routers. Sized to the data the device actually uses, from light back-office cover through to heavier router and failover use, confirmed at quote.
Multi-network business SIMs (Anywhere SIM)
A SIM that isn't locked to one carrier — useful where kit genuinely roams between sites, or coverage varies enough that a single network is a risk. Exact behaviour depends on the specific product, which we'll explain before you order. Not the default: for most office and staff use, a standard SIM on the right network works out more cost-effective. More on how Anywhere SIM works ›
Specialist SIMs
Purpose-built SIMs for payment terminals, telematics, alarm panels, lift lines, gate entry and door intercoms — equipment that stays put and needs to work every time, not a phone someone carries around. Priced and specified separately since the requirements are different from a staff SIM.
Business SIMs through EE, O2, Vodafone & multi-network partners
We arrange suitable business mobile plans across the providers below, plus multi-network options where that's the better fit. The right one depends on coverage at your locations, indoor signal, how your team works, and what the device needs — we check before recommending, not after you've ordered.
EE business SIMs
Available through selected tariffs, subject to coverage and availability at your locations.
O2 business SIMs
Available through selected tariffs, subject to coverage and availability at your locations.
Vodafone business SIMs
Available through selected tariffs, subject to coverage and availability at your locations.
Multi-network SIMs
Switches across networks rather than one carrier — for roaming kit and coverage-critical sites.
Business SIMs for teams of every shape
- Sole traders
- Small and medium-sized businesses
- Office-based teams
- Field engineers
- Sales teams
- Care and support organisations
- Retail and hospitality businesses
- Fleets and mobile workforces
- Rural businesses
- Businesses needing backup connectivity
What actually decides which plan fits
The cheapest SIM isn't always the right one. Worth thinking through before you order: how many users, expected data use, calls and texts needed, the device it's going in, physical SIM or eSIM, single-network versus multi-network, 4G or 5G requirements, roaming abroad, contract length, whether numbers need porting, and coverage at the actual locations the SIM will be used.
| Requirement | Suitable option | Typical example |
|---|---|---|
| Staff phones, single office or region | Standard single-network SIM-only | Sales team on the network with best local coverage |
| Tablet, laptop dongle or router | Business data SIM | Data-only SIM sized to the device's actual usage |
| Kit that moves between unpredictable sites | Multi-network SIM | Telematics unit or payment terminal used at different venues |
| Backup behind a primary broadband line | 4G backup SIM in a router | Failover SIM that activates automatically if the main line drops |
| Fitted, single-purpose equipment | Specialist SIM | Lift line, gate entry panel or alarm autodialler |
How pricing works
SIM pricing depends on the network, allowance and device the SIM is for, so we quote the exact figure once we know what you need rather than lead with a single headline rate. Most plans run 30-day rolling; 12 or 24 month terms are available where a longer term brings the per-month cost down. Setup, porting or hardware costs (if any) are confirmed at quote, not added afterwards. We call every enquiry back personally before anything is ordered or activated, that's when we confirm your figure. Pricing is subject to change and to the eligibility, availability and terms of the selected network.
Number porting and eSIM
Existing business mobile numbers can usually be transferred across, subject to your current provider and account requirements — give us the number and current network and we'll confirm before you switch. Accurate PAC or porting information when we ask for it keeps this quick.
Physical SIM or eSIM may be available depending on the device and tariff — we'll confirm what your specific handset or equipment supports at quote rather than assume every device and plan works the same way.
Combines with everything else we supply
SIMs sit on the same account as broadband, VoIP and leased lines if you take more than one service from us — one invoice, one point of contact, whether it's 2 SIMs or 200.

What is a business SIM-only contract?
A SIM card on a business account with no handset included — you use your own phone, tablet or router and pay for the airtime and data plan only. It's the standard option for staff and company phones.
Can I get a business SIM without a phone?
Yes. SIM-only is the default for business plans — you keep your existing handset (or buy one separately) and we set up the SIM and airtime plan against your business account.
Can I use my existing handset?
In almost all cases, yes, provided it's unlocked or already on a compatible network. We'll flag it if a specific device needs checking.
Which mobile networks are available?
We arrange business SIMs through EE, O2 and Vodafone, plus multi-network SIMs that aren't tied to a single carrier. Which one suits you depends on coverage at your locations, device type and how the SIM will be used — we check before recommending.
Do you provide EE, O2 or Vodafone business SIMs?
Yes to all three, available through selected tariffs, subject to coverage and availability at your locations.
What is a multi-network SIM?
A SIM that can connect across more than one mobile network rather than being locked to a single carrier. Exact behaviour depends on the specific product — we'll explain how the one we recommend works before you order.
Is a multi-network SIM better than a standard SIM?
Not automatically — it usually costs more, and for most office and staff use a standard single-network SIM on the right carrier is the more cost-effective choice. Multi-network earns its premium for roaming equipment, payment terminals, or sites with unpredictable coverage.
Can I keep my existing mobile number?
In most cases, yes, subject to your current provider and account requirements. Give us the number and current network and we'll confirm porting before you switch.
Do you provide business data SIMs?
Yes, data-only SIMs for tablets, laptops, dongles and routers, sized to the data allowance the device actually needs, confirmed at quote.
Can I use a SIM in a 4G or 5G router?
Yes, for both a primary connection and 4G backup behind an existing line, subject to the tariff and signal at the router's location.
Do you provide eSIMs?
Where the device and tariff support it, yes. We'll confirm eSIM availability for your specific handset or equipment at quote.
Can I get SIMs for payment terminals or IoT equipment?
Yes — see our specialist SIM range for card terminals, telematics, alarm panels and similar fitted equipment.
How many SIMs on one account?
No fixed limit. Whether you need 2 or 200, all managed under a single account with one invoice.
What information do you need to provide a quote?
How many SIMs, roughly what they're for (staff phones, a router, equipment), current network if you're porting numbers, and where they'll be used. We'll come back with suitable options the same day in most cases.
Tell us about your team.
How many SIMs, what they're for, current network if porting. We'll come back with suitable options that fit, no pricing tie-in on this form, we tailor it to you.
