How to block numbers from texting or calling you in iOS
If you're running iOS 7 or later, you can stop those telemarketers and chronic wrong-number dialers with this quick and easy trick.
We’ve all been there. The survey takers keep trying to reach you, or the person who keeps dialing you with the wrong number, never seeming to realize that you’re not the person they’re looking for. Blocking numbers usually requires the assistance of your cell provider, but with iOS 7 or later, you can block selected people from calling, texting, or starting a FaceTime session with you.
If you want to block someone, you can go about it either using the Phone, FaceTime, or Messages apps, or through the Settings app. To block someone already on your contacts list, open the Phone app, select a contact card, scroll down toward the bottom, and tap Block this Caller. If you’re blocking someone in your Recents list of the Phone app, you’ll need to tap the ”i” to get their contact card, but aside from that, the process is the same.
From Messages, go to a conversation, tap Details, then tap the “i” icon next to their name. Look toward the bottom of the contact card that appears and tap Block this Caller. In FaceTime, find the person you want to block in the contacts, tap the “i” button, then tap Block this Caller. The person you want to block may appear on the Video tab but not the Audio tab in FaceTime—and vice-versa—so you may need to poke around a little.
If you want to edit your blocked list more quickly, open the Settings app, then go to either Phone, Messages, or FaceTime settings; scroll down to Blocked, and you can add or remove people from your blocked list. To add someone, tap Add New...; to remove someone, swipe a person’s name from right to left, then tap the Unblock button that appears.
This feature works on the iPad as well, via the Messages and FaceTime apps. You can also go through Settings > FaceTime and Settings > Messages, as outlined above.
Remember, if you block someone, they won’t be able to call you, send you text messages, or start a FaceTime conversation with you. You can’t block someone from texting you while allowing them to call. Keep this in mind, and block responsibly.
