You can block a caller on an iPhone so calls, messages, and FaceTime communications from that contact or number are handled as blocked communications. The iPhone 5 is now a legacy device, so the exact interface depends heavily on the old iOS version installed.
Block a number from the Phone app
- Open Phone.
- Choose Recents.
- Tap the information button beside the number or contact.
- Scroll through the contact details and choose the option to block the caller if your iOS version provides it.
- Confirm the block.
Block a saved contact
You can also manage blocked contacts through the Phone, Messages, or FaceTime settings available on the installed iOS release. Apple’s menu locations have moved over the years, so an older iPhone 5 may not match instructions written for a current iPhone.
Blocking is not the same as reporting spam
Blocking stops the number from reaching you through supported Apple communication features, but it does not necessarily report the caller to your carrier or prevent spoofed calls from a different number. Use carrier spam-reporting tools or applicable reporting services for unwanted calls when appropriate.
Unblock a caller later
Open the blocked-contact list in Settings and remove the number from that list. You do not need to delete and recreate the person’s contact card.
The iPhone 5 cannot run current iOS releases and no longer receives modern security updates. Avoid using such an old device for sensitive accounts or financial activity. If the phone remains in use for basic calling, expect current Apple support instructions and app compatibility to differ substantially from the device.
