Equip your estate agents with UK Business Numbers.
Zero hardware. Instant team onboarding. One centralized invoice. Deploy business eSIMs to your agency branches in seconds.
Estate agents need a professional business line to manage viewings and client negotiations, but buying physical work phones is expensive and managing reimbursable SIM receipts is terrible. SecondSim provides zero-friction UK business mobile numbers that deploy directly to your team's existing smartphones. Perfect separation, universal WhatsApp Business support, and one clean monthly invoice.
The old way of managing agency phones is broken.
Your branch hires a new letting agent. You have to order an expensive secondary handset, wait three days for the post, and walk them through setting up a new SIM.
Meanwhile, your finance team is dealing with a mountain of individual employee expense claims for mobile bills every month.
It's 2026. You shouldn't be shipping plastic to connect your team.
- Finance wastes hours reimbursing individual agent mobile bills
- Agents use their personal numbers for viewings, blurring professional boundaries
- When an agent leaves for a competitor, the local client numbers leave with them
- Buying "company phones" is a massive upfront hardware cost
SecondSim Team Management solves all of this instantly.
Centralized billing. Instant deployment.
SecondSim transforms how agencies handle telecom. Instead of issuing physical phones, you assign digital UK mobile numbers directly to your team's existing devices via our zero-touch admin dashboard.
When a new agent joins, click "Send to Employee" and they receive a QR code via email that instantly activates a secure, secondary business line on their iPhone or Android. They get a professional number for viewings, verify WhatsApp Business instantly, and you get one simple monthly corporate invoice for the whole team.
Create Admin Account
Takes 2 minutes to set up your corporate billing profile.
Add Employees
Add team members to your dashboard and we'll automatically generate real UK numbers.
Instant Dispatch
Click "Send QR" and your employee receives instant activation instructions via email.
Total Control
If an employee leaves, simply revoke the eSIM with one click and reassign the number to their replacement.
Why smart agencies use SecondSim team management.
Eliminate Expense Claims
Stop paying HR and Finance teams to manually process dozens of individual £10-£15 mobile bill receipts every month. All your employees' data and calls are consolidated into one corporate invoice.
You own the numbers
When agents use their personal numbers for viewings, client relationships leave with them. With SecondSim, the agency owns the number. When an associate leaves, you just reassign the QR code to the new hire.
Zero Hardware Costs
Stop buying £800 secondary smartphones for your team. Bring-Your-Own-Device (BYOD) is the modern standard. Our eSIM technology allows your team to run a fully separate, secure business line on their existing iPhone or Android.
Port your existing team
Have numbers locked in legacy EE or Vodafone contracts? Our dashboard allows you to submit PAC codes and seamlessly port your entire existing company team over to zero-hardware eSIMs instantly.
Perfect boundaries for your team
Estate agents burn out because the phone is always on. A dedicated SecondSim line allows your team to toggle off their "work network" on Sundays, suppressing all client calls and texts until Monday morning.
Why not just use a free virtual number app?
Good question. A lot of freelancers try this first. The problem is that VoIP numbers, the kind used by apps like Google Voice, Hushed, and similar, are blocked by the platforms you rely on most.
WhatsApp will ban your account. Banks won't accept them for two-factor authentication. Stripe, PayPal, Shopify, and Etsy actively reject them.
SecondSim is different. We're a UK telecoms operator. We issue real, carrier-grade mobile numbers that are fully accepted everywhere. It's not a workaround. It just works.

Frequently Asked Questions
How do I pay for multiple employees?
Your single dashboard account will hold the master credit card on file. Each time you deploy a new eSIM to an agent, your company card is automatically billed one transparent, consolidated invoice.
Will it work with our team's existing WhatsApp Business strategy?
Yes. SecondSim numbers are real UK mobile numbers, meaning your team can securely authenticate WhatsApp Business accounts on their phones using our numbers without being blocked like VoIP lines.
Do I need to check my employee's device compatibility?
Most modern devices (iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer) support eSIMs natively. Employees simply scan the QR code we email them.
How quickly can I onboard a new hire?
Less than 60 seconds. You enter their name in the dashboard, and an activation QR code shoots to their email inbox instantly.
Can we port existing agency numbers to you?
Yes! If your team is stuck in a Vodafone or EE physical contract, just request a PAC code from them and you can effortlessly port the mobile team to SecondSim inside your dashboard.
What if an agent is let go?
Because your company owns the numbers, you can instantly terminate the eSIM's network connection from the admin dashboard and reallocate the telephone number to a new hire.
