how to make it so people cant black their number

how do u make it so other people cant call u with a blocked number and can u block certain people from calling u

It all depends on your service. There is no real way to block people from calling you but you can block from txt you. There is no way to make it so people cant call you with a blocked number. My suggestion is just not anwser blocked calls... It keeps telemarketers away and people who really arnt your friends

This might work depending on the model phone you are using. Say a certain someone keeps calling to bug you. Put that phone number in your phone book and turn the custom ringer to None so when they call the phone does not ring and you don't have to bother answering. It will go to voice mail and you can delete it without listening if you want.
