How to Block Calls From Telemarketers and Others
Blocking occurs within the Phone app:
What Is Blocked?
What types of communication are blocked depends on what information you have for this person in your address book:
If you have their phone number, they’re blocked from calling you, placing FaceTime calls, or sending you texts from the phone number saved on your phone. If you have their email address, they’re blocked from texting you through iMessage or placing FaceTime calls using the blocked email address.
Whatever you block, the setting only applies to people using the built-in Phone, Messages, and FaceTime apps that come with the iPhone. If you use apps from other vendors for calling or texting, these settings won’t block people from contacting you. Many calling and texting apps offer their own blocking features, so you may be able to block people in those apps with a little research.
What Do Blocked People See?
The people you block have no idea you blocked them. That’s because when they call you, their call goes to voicemail. The same with their texts; they won’t see any indication that their text didn’t go through. To them, everything will seem normal. You can still call or text them if you want, without changing your block settings. While there’s no way to know for sure, there are a few ways to figure out if someone blocked you, so if the people you blocked grow suspicious, they might be able to figure it out.
