Frequently Asked Questions
Everything you need to know about using SecondSim for SMS verification.
Will this work for Bank and financial verification? +
Yes. Unlike VoIP numbers (Skype, Google Voice) which are flagged by automated fraud algorithms as 'high risk', SecondSim provides genuine mobile numbers on Vodafone UK's cellular infrastructure. It receives shortcode OTPs from Monzo, Barclays, HSBC, and Stripe exactly like a standard contract SIM card.
Is this a VoIP number? +
No. SecondSim is allocated directly on Tier-1 UK mobile network infrastructure. It identifies as a legitimate 'Mobile' connection across all HLR queries and carrier lookups.
Can I use this for WhatsApp Business or Tinder? +
Yes. This is the primary use case for many of our users. Because it is a legitimate mobile line with an active MNC, you avoid 'unsupported phone number' errors and instant account bans.
How long does setup take? +
Instant. As soon as you complete your purchase, you receive an instant QR code. Scan it to install the eSIM, and your line is active within 60 seconds.
Do I need a second physical phone? +
No. SecondSim installs over the air onto your existing dual-SIM smartphone via an eSIM profile. You can keep your personal SIM for everyday use and SecondSim for verifications and work communications.
