How to Know if Someone Blocked Your Number
1: Unusual Messages When You Call
If you get an unusual message you haven’t heard before, they’ve likely blocked your number through their wireless carrier. The message varies by carrier but tends to be similar to the following:
“The person you are calling is unavailable.”
“The person you are calling is not accepting calls right now.”
“The number you are calling is temporarily out of service.”
2: The Number of Rings
If you hear only one ring or no ring at all before your call goes to voicemail, this is a good indication you’re blocked.
3: Busy Signal or Fast Busy Followed by Disconnect
If you get a busy signal or fast busy signal before your call is dropped, it’s possible your number is blocked through their wireless carrier.
