SecondSim for Revolut:
✓ Verified Compatible
Revolut blocks virtual VoIP numbers. SecondSim provides genuine UK mobile lines on Vodafone's physical cellular network that pass automated security checks and receive 2FA codes immediately.
Automated carrier lookup checks recognize SecondSim as a legitimate mobile subscriber on Vodafone UK core network.
Why VoIP Numbers Fail on Revolut
Understanding why virtual app numbers get blocked and how genuine UK mobile infrastructure solves the problem.
Revolut holds an e-money licence from the FCA and applies strict phone number validation during onboarding. Their system uses a real-time carrier lookup API that classifies numbers into Mobile, Landline, VoIP, or Virtual categories. Only numbers classified as "Mobile" pass verification.
Additionally, Revolut maintains an internal database of known VoIP number ranges from providers like Twilio, Vonage, and Bandwidth. If your number falls within these ranges, the SMS is never dispatched — you simply never receive a code, with no error message explaining why.
SecondSim numbers are provisioned directly on UK mobile network infrastructure, receiving a genuine MSISDN (Mobile Subscriber Integrated Services Digital Network Number). When Revolut's carrier lookup API queries your number, it returns classification "Mobile" with a UK carrier attribution — passing their filters identically to a traditional contract SIM.
This means instant SMS delivery for verification, and full compatibility with Revolut's ongoing 2FA challenges for transactions, login, and settings changes.
