I call and the person says,"The person you are trying to reach does not except call from blocked numbers."

You don't unblock your number. The person you are trying to call has to unblock you.

I think its referring to the fact that your number is set to private.

If your calling from a mobile all you need to do is change your call settings. It would probably be under "show caller id" or something.

If you're calling from a land line you need to contact your service provider and have it changed so that when you call someone it shows them you are calling.

Good Luck

We do need to know if this is a cell or land line you are using. Land lines are blocked by you on your own phone and only you can unblock it, no service provider can do it for you. *67 is the code to block both land lines and cell phones. Try *82 or 1182 to unblock.
