Why businesses choose SecondSim for Teams
Centralised Management

Unified Billing
One monthly invoice for your entire team. No more processing individual physical SIM receipts or chasing down expenses.
Zero-Touch Onboarding
Onboard new hires instantly. Send a 1-click activation email to their inbox and they'll have a working UK business number in seconds.
The problem with VoIP business phone numbers
Virtual "app-based" lines use VoIP (Voice over IP) technology. Because anyone can generate them instantly for fraud, platforms actively block them. SecondSim is radically different. We provide a non-VoIP, carrier-grade mobile network profile that lives directly on your phone's SIM hardware.
This guarantees it won't be blocked. You can securely activate a WhatsApp Business account, receive OTPs from Stripe, PayPal, Monzo and Barclays directly to your native messages app. Check if your current number is VoIP here.
Technical Advantage
- Competitors (VoIP):
- Providers like Aircall and Google Voice use virtual routing. WhatsApp and UK Banks flag these as 'Landline' or 'Virtual', triggering instant security blocks.
- SecondSim (GSMA Core):
- Installs directly to your phone's secure enclave as an eSIM profile (MNC-UK-MOBILE-CORE). It bypasses automated VoIP filters entirely, guaranteeing 100% verification success.
Instant setup. No hardware required.

Frequently Asked Questions
Can I have two phone numbers on one phone in the UK?
Yes, absolutely. Most modern iPhones and Android devices support dual SIM (or eSIM) technology. You simply scan our QR code to install a second profile, enabling you to use your existing personal line and your new business number side-by-side.
Is this a VoIP number or a real mobile number?
This is a real mobile number powered by a UK cellular network. It is strictly not VoIP. VoIP lines are heavily blocked by applications, but our carrier-grade guarantee ensures you do not get blocked by automated filters.
Will it work with WhatsApp Business?
Yes. Setting up a WhatsApp Business number is our most popular use case. Our mobile numbers receive the registration SMS or call perfectly the very first time.
Can I use it to receive bank verification codes?
Yes, it works flawlessly for bank 2FA and OTP verifications including Monzo, Starling, Revolut, Barclays, HSBC, and traditional merchants where VoIP drops messages.
Do I need a contract or credit check?
No. We value speed and access. You sign up, bypass credit checks entirely, provide no ID, and agree to zero lengthy contracts. It is fully pay-as-you-go rolling.
How quickly can I activate it?
Instantly. Once you checkout, you will immediately receive a QR code in your inbox. Scanning it with your camera adds the profile, making you active within minutes.
What happens if I want to cancel?
Our systems are fully self-serve. You can log into your dashboard and cancel your monthly rolling subscription instantly with a single click. No hidden retentions team to speak to.
Can I give this number to employees?
Yes. Small and medium businesses love using SecondSim for employee numbers because it avoids hardware costs. Use our dashboards for teams to maintain central billing and oversight.
Does it work abroad?
Yes. You can receive inbound SMS messages and OTPs globally at no additional charge. For outbound roaming needs, see our digital nomad and expat guidance.
What's the difference between SecondSim and a VoIP app like Google Voice or Skype?
VoIP lines (like Skype and Google Voice) generate virtual numbers over the internet. Major financial platforms and WhatsApp actively detect and block these. SecondSim operates on actual cellular network bands, acting identically to physical SIM hardware issued by major telecom operators.
