Remote telecom provisioning is broken.
When you hire a developer in literally any other country, IT has to order a handset, jump through customs hoops, and pay exorbitant shipping fees just to give them a company phone number for Slack 2FA and client calls.
It's 2026. Hardware shouldn't be a bottleneck for distributed talent.
- Shipping physical company phones globally costs thousands in logistics and hardware
- VoIP numbers get flagged as spam and fail SMS 2-Factor Authentication
- Employees hate carrying two separate mobile devices
- Reimbursing employees for using their personal numbers creates HR and Finance friction
SecondSim Team Management solves all of this instantly.
Centralized billing. Zero touch deployment.
SecondSim transforms how modern companies handle remote telecom. Instead of managing hardware logistics, you deploy digital UK mobile numbers directly to your team's existing devices over-the-air via our admin dashboard.
When a remote hire joins, enter their email and click "Send to Employee." They instantly receive a QR code that activates a secure, secondary business line on their personal iPhone or Android. They get a professional number for global team collaboration, 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 remote team members to your dashboard and we'll dynamically allocate real UK numbers.
Instant Dispatch
Click "Send QR" and your employee receives instant activation instructions via email, globally.
Total IT Control
If an employee leaves, simply revoke the eSIM with one click and reassign the corporate number to their replacement.
Why modern IT teams use SecondSim team management.
Real Numbers, not VoIP
Unlike virtual apps that get flagged as spam or rejected by WhatsApp and Stripe 2FA, SecondSim issues carrier-grade, genuine UK mobile numbers.
Centralized IT Control
Stop leaving valuable client contacts and 2FA access tied to a former employee's personal device. You hold the master switch to instantly revoke or re-issue any number.
Zero Hardware Budgets
Bring-Your-Own-Device (BYOD) is the standard for modern companies. Run a fully separate, highly-secure corporate line on an employee's existing smartphone.
Instant Global Onboarding
Whether your new hire is in London, Lisbon, or Latin America, you can equip them with a corporate UK business number within 10 seconds.
Eliminate Expense Claim Admin
Stop paying HR to comb through individual mobile phone receipts sent over Slack. Your entire workforce is grouped into one predictable, monthly corporate invoice for your finance controller.
Why not just use a free virtual number app?
Good question. A lot of remote-first teams try this first. The problem is that virtual VoIP numbers—the kind issued by apps like Google Voice, Hushed, and Skype—are flagged as spam by security gates. Critical tools like WhatsApp Business, AWS, Slack, and corporate bank accounts will reject VoIP numbers for two-factor authentication or lock your accounts. SecondSim is different: we issue real UK carrier mobile numbers that work natively with every verification gate.

Built for scale-ups and global native teams.
SecondSim operates perfectly on devices around the globe, providing reliable 2FA infrastructure and secure local UK footprints:
Provide corporate numbers for AWS alerts, PagerDuty, and secure server 2FA without compromising personal data.

Instantly onboard new hires around the world without purchasing a massive team of £1,000 corporate iPhones.

Stop shipping company hardware.
The modern workforce requires modern tooling. Equipping a remote employee with a physical secondary handset is as outdated as sending them a fax machine. Shift to zero-hardware team management today.

Frequently Asked Questions
How do I pay for a globally distributed team?
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, completely converting forex costs dynamically if you are abroad.
Are these VoIP numbers? (Like Google Voice/Skype)
No. SecondSim numbers are real, carrier-grade UK mobile numbers. They don't get blocked by the spam filters that block VoIP numbers, making them completely compatible with secure banks, 2FA gateways (like AWS or Slack), and WhatsApp Business.
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 physical team 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 to migrate them to digital eSIMs.
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, keeping client accounts intact.
