Blocking a number on an iPhone prevents that contact from reaching you via phone calls, FaceTime, or text messages (SMS/MMS). This is a user-controlled, device-specific feature tied to your Apple ID and iCloud, but it does not block the person across all apps (e.g., WhatsApp, Telegram). blocked phone numbers iphone
