Why Banks, 2FA and WhatsApp Business Reject Virtual Numbers

When a virtual number is rejected for 2FA, it is usually because banks and apps check the number type and block internet routed numbers. A real UK mobile number on the mobile network passes those checks.
Why are virtual numbers rejected?
Verification systems assume a mobile number belongs to a real person on a mobile network. Virtual numbers routed over the internet fail that check.
What passes instead?
A native mobile number. ZIM UK numbers run on Vodafone UK, so they receive SMS codes at home or abroad, work for UK bank onboarding and register on WhatsApp Business.
