The Second Number That Actually Receives Codes
Real UK Mobile SIM (Non-VoIP) for guaranteed verification on all apps.
Why Free Apps Fail (and SecondSIM Works)
Most "second number" apps use VoIP (Voice over IP). Banks and dating apps categorize these as "high risk" and block them instantly. SecondSIM is different. We issue you a real mobile number from a Tier-1 UK Network.

Frequently Asked Questions
Will this work for Bank verification?
Yes. Unlike VoIP numbers (Skype, Google Voice) which are often flagged as "high risk," SecondSIM provides a genuine mobile number from a major UK network. It receives OTPs from Monzo, Barclays, HSBC, and others exactly like a standard SIM card.
Is this a VoIP number?
No. This is a Tier-1 UK Mobile network number. It identifies as a "Mobile" connection to all apps and services, ensuring your verification codes are delivered instantly.
Can I use this for WhatsApp Business?
Absolutely. This is the primary use case for many of our users. Because it's a real number, you won't face the "unsupported phone number" errors common with virtual providers.
How long does setup take?
Instant. As soon as you complete your purchase, you receive a QR code. Scan it to install the eSIM, and your number is live within minutes.
Do I need a plastic SIM card?
No. SecondSIM uses eSIM technology. It works digitally alongside your existing SIM card. You can keep your personal number for calls and use SecondSIM for verifications.
