When you call a blocked number, the experience can be different depending on the phone and settings of the person who blocked you. However, there are some common signs that indicate you have been blocked:

• You may hear one ring or half a ring, or no rings at all before the call goes to voicemail.
• The call may go straight to voicemail without ringing.
• If you leave a voicemail, it may not go to the recipients inbox but instead to a separate location for voicemails from blocked numbers.
• You wont get a missed call or voicemail notification if the person you blocked calls your number.
• If you call someone who has blocked you, you may hear an automated message saying that the customer is unavailable.
• If you make a call and receive an automated message along the lines of “the customer is unavailable,” then you may have been blocked by that person’s wireless carrier.
• If you call and it goes straight to voicemail, it means you are not blocked, and the person is already on a call or their phone is off.

Its important to note that if you have been blocked, it may be for a good or bad reason, and its best not to press the issue too hard as you risk breaching someones privacy.
