The guy that I've been talking I said I blocked his number and he going to block mine. How do you know if someone blocked you? I tried calling him with the *67 unknown number and it rang normal up to five times and went to voicemail, I know he didn't answer because he's at work. I"m not sure what type of phone he has. But maybe did he just blocked me texting him and not calling him? How do you know if someone blocked you?
