Hello, Yes, you can block a cell phone number. You can use *67 before dialing the number. I found this out from the resource below.

Absolutly! call your wireless company and tell them youd like a Restraint on a phone number..and theyll make sure that best will never call u again! i hate ex-boyfriends..haha

I wish, this dumb hillbilly kept calling my phone and leaving voicemails because he thought i was someone else. I answered once and said he had to wrong number and to stop calling. I still got calls after a while but I guess the idiot figured he wasn't getting an answer so why bother. Lol, call the company if you're desperate or change your number. I would just change my number.

have you tried asking that retarded person to stop calling? or get a caller ID so whenever that person call you, you can tell that it is that person, so don't pick up the phone : D

You can't block calls on a cell phone, but on some phones, you can text. Just ignore the call. Set a really annoying ringtone or something to it, so you ignore right away.

I wish it was possible but you can't block any #'s on a cell phone

call the phone company and tell them the number you want blocked.
