Account security: SIM changes and port-outs
Where it breaks today
- A SIM change is approved on a phone call, with knowledge questions a fraudster can answer.
- Port-out requests arrive from the new carrier and are released before the customer knows.
- Each channel applies different checks, and nothing proves which ones ran.
What Callvu enforces, on the record
- Every SIM change and port-out passes secure authentication before it runs, from any door.
- The customer is notified on the contact on file, and a step-up is required when the risk is high.
- Every request, check and release is in the Audit Trace.
- Written to your system of record, with the Decision Trace and Audit Trace
Where a typical carrier struggles most:
- SIM changes
- Port-out requests and PIN resets
- Account takeover reports
Rule: The FCC SIM swap and port-out rules and CPNI authentication, enforced at runtime
