1. Per-Service Isolation: How Number Reuse Is Prevented
A critical security question is: “If I rent a US (+1) number to verify Telegram today, could another user rent that same US (+1) number for Telegram tomorrow and access my account?”
On NEXUSOTP, the answer is No:
- Every physical SIM number maintains a per-service allocation registry.
- Once a number
