How to block unknow callers from calling you
Unknown callers? No particular way. If they consistently use the same number, you can use a phone's built in call block if you hgave a phone with such a feature and you do. Go to settings, phone, call blocking and notification. If they're spammers that use random numbers, you can jsut ignore it until they go away. If they consistantly use the same area code, for example, you could block that, but you block all numbers from that area code.
