The old way of managing agency phones is broken.
Your firm hires a new associate. 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 employee mobile bills
- Associates use their personal numbers for clients, blurring professional boundaries
- When a consultant leaves, you have zero control over the client communications
- 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 consultant 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 clients, 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 Invite" 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 consultants use their personal numbers for client communications, client relationships leave with them. With SecondSim, the agency owns the number. When an associate leaves, you just send a new installation link 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
Remote work causes burnout because the phone is always on. A dedicated SecondSim line allows your team to literally toggle off their "work network" at 6 PM on Friday, 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.

Built for professional services that travel.
SecondSim operates on the Vodafone network in the UK, ensuring reliable connectivity wherever your associates are deployed:
Need a dedicated line for client interviews that can be transferred if a partner switches accounts.
Empower your sales reps with WhatsApp Business accounts mapped to official company numbers, ensuring leads stay within the CRM.
Maintain high-availability lines to pitch journalists and field media requests without mixing personal phone logs.
Scale your account managers up or down with instant number provisioning during new client acquisition sprints.
Stop managing physical phones.
The modern workforce requires modern tooling. Equipping an associate with a second handset is as outdated as providing them with a typewriter. Shift to zero-hardware team management today.

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 employee, 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 click the 1-click install link 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 1-click link 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 employee 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.
