Not every unknown call is a threat, and not every familiar number is safe. Here's a useful detail most people overlook:
If you used your carrier's spam-blocking tool (T-Mobile Scam Shield, AT&T ActiveArmor, Verizon Call Filter) to block a number, that block is separate from iPhone's built-in block list. Unblocking in iPhone Settings does not affect carrier-level blocks.
