Your team doesn't need company phones.
They need company numbers.
SecondSim gives every employee a real UK business number on the phone they already own, from just £5.99 a month.
Company mobiles made sense once. Not today. Handing staff a second phone just creates hassle, cost, and a drawer full of devices nobody wants to carry. There's a smarter way to give your staff a professional business number, keep work and personal separate, and manage it all in one place. No hardware. No contracts. No nonsense.
Trusted by 1,000+ teams.
The problem with traditional company phones
The average business mobile contract with a handset costs around £45 per employee per month. That's before you factor in the upfront cost of the device, the admin of managing contracts, chasing upgrades, and dealing with lost or broken phones.
And at the end of it all? Your employee still uses their personal phone for half their work calls anyway.
- 5 employees: ~£2,700/year
- 10 employees: ~£5,400/year
- Plus handsets: add £300–£1,200 per device upfront
That's a significant chunk of money leaving your business every year. SecondSim solves the problem at a fraction of the cost.
One eSIM. One business number. Works on the phone they've already got.
SecondSim is a real UK telecoms operator. We give each member of your team a genuine carrier-grade mobile number, not a VoIP app, not a virtual workaround, delivered as an eSIM directly to their existing smartphone.

Done. They have a real UK business number. You have one simple monthly bill.
No IT team required. No procurement process. No waiting around.
The numbers are pretty hard to argue with.
| Team Size | Traditional Contracts + Handsets | SecondSim | Annual Saving |
|---|---|---|---|
| 3 employees | £1,620/year | £215/year | Save ~£1,400 |
| 5 employees | £2,700/year | £359/year | Save ~£2,340 |
| 10 employees | £5,400/year | £719/year | Save ~£4,680 |
| 20 employees | £10,800/year | £1,438/year | Save ~£9,360 |
Based on standard business contract cost of £45/month per employee vs SecondSim billed at £5.99/month per seat on a monthly plan.
That enormous saving doesn't even include the cost of handsets which at £500–£1,000+ per device adds up astronomically fast for a growing team.
And unlike a traditional contract, there's no 24-month lock-in. Add a seat when you hire. Remove one when someone leaves. Pay only for what you actually need.
Everything your team needs. Nothing they don't.
Real UK mobile numbers
Not VoIP. Not virtual. Genuine carrier-grade numbers that work perfectly with WhatsApp Business, banking apps, Stripe, PayPal, and every platform that strictly blocks cheap virtual numbers.
Unlimited UK calls & SMS
Every seat includes unlimited calls and texts. Your team can call clients, take orders, and handle enquiries — just like a normal business phone, without the monstrous business phone bill.
Instant deployment
New starter on Monday? Their number is ready before they sit down. Send the QR code directly from your dashboard with one click. Activated in minutes, zero IT involvement needed.
Central billing
One invoice. One simple monthly amount. Not five separate complex contracts with three different networks hitting your account on different dates. Simple and predictable.
Full control
Manage all your team's numbers from a single intuitive dashboard. See who's active, instantly add new seats, or cleanly remove leavers. You're always in complete control without being in the weeds.
BYOD by default
Your team use their own phones — which they prefer anyway. You stop buying, insuring, tracking, and replacing expensive hardware. That's a headache you never have to deal with again.
We've heard the questions.
Here are the answers.
"What if an employee leaves?"
Cancel their seat from your dashboard instantly. Their number is deactivated on their device, but you can securely reassign it to their replacement so you don't lose client contacts. No contract to untangle, no network to call, no physical handset to chase.
"What about data? Our team needs mobile data."
SecondSim covers all calls and SMS which handles client communication, WhatsApp Business, and verifications. Your team's existing personal data plan simply covers everything else, exactly as it does now. Practically everyone already has more data than they use.
"Is this actually a real number or some kind of VoIP app?"
It is a 100% real number. SecondSim is an official UK telecoms operator issuing genuine carrier-grade mobile numbers. They work everywhere a normal physical mobile number works and are trusted by every platform that rigorously blocks VoIP alternatives.
"Our team might not know how to set it up."
The setup takes exactly two minutes and works identical to adding a new physical SIM card. We provide a full, easy-to-follow guide for both iPhone and Android devices. If anyone gets stuck, we're here to help.
"We're already locked into a contract."
Fair enough. SecondSim will be here when it expires. But at this massive price difference, it's definitely worth knowing your options before you automatically renew those £45/mo contracts.

Frequently Asked Questions
Do employees have to give up their personal number?
Not at all. SecondSim sits completely alongside their personal physical SIM on their existing phone. They simply have two active mobile numbers — one personal, one strictly for work — managed cleanly on the same device.
How many seats can I manage?
As many as you require. Add seats one at a time exactly as your team grows. There's no minimum or maximum seat limit.
Can I keep a number if an employee leaves?
Absolutely. You can easily "park" a number for just £2.99/month to deliberately preserve it, and then instantly reassign it safely to a new hire when the time eventually comes.
Is there a free trial?
We confidently offer a bulletproof 7-day money-back guarantee. If it doesn't work perfectly as promised, you get a full, unconditional refund.
Do the numbers work for WhatsApp Business?
Yes, absolutely guaranteed. Our numbers are 100% real, non-VoIP UK mobile numbers, which is the exact technical requirement needed to properly verify and run WhatsApp Business.
