"SMS code never received" "Bank page blocked, payment failed" "3D Secure timeout, order not placed"

Summary

Why do 3D Secure payment errors generate support requests?

This problem occurs when a 3D Secure block during payment blocks the customer or creates doubt.

Support must first understand the cause, then explain the solution without blaming the customer.

  • Failed authentication: bank validation refused

  • missing security code: code never received

  • Banking app timeout: mobile validation expired

  • Blocked window: mobile browser blocks 3D Secure

  • Validation abandoned: customer closes 3D Secure window
