This article explains several ways you can check if your iPhone has been blocked by someone. There is no foolproof way to tell if someone is blocking your calls on their iPhone other than looking at their phone and checking the list of blocked numbers. However, there are some telltale signs that they have blocked you.
How do you know if someone has blocked you on your iPhone?
If your calls go unanswered and your texts never get returned, the best thing to do is to just ask them directly: Did you block me on your phone? There is a chance that they did and they didn't do it on purpose.
If you're having a hard time asking if they blocked you, try these ideas.
The biggest indicator of a blocked call is a single ring that goes to voicemail. However, this does not mean that you are blocked for good. If the other person is on their phone at the time, especially if they are talking to someone else, they may choose to accept or decline the call. This could explain a call that quickly goes to voicemail. Another possible situation where the other person’s phone goes straight to voicemail is if the other person’s phone is turned off or the battery is dead.
