Start with interruption reduction
No single tool stops every unwanted call or text. The useful approach is layered: registry protections where applicable, carrier filtering, device filtering, individual blocking, and reporting.
Be careful with suspicious messages
Do not open unexpected links or provide personal information merely to investigate a message. If an opt-out instruction is appropriate and you choose to use it, keep a record of what you sent and whether contact continued.
Report through the right channel
The FTC and FCC accept reports about unwanted calls and texts. Their complaint systems serve different purposes, and a report does not mean an individual enforcement case or carrier traceback will automatically be opened.
