Annoying and unwanted phone calls can become a plague to mobile phone users. Mobile service providers now offer a solution to this problem through call block. This service allows users to create a list of blocked callers for any number on their account. The fee for call block will vary based on your mobile service provider. Once calls are blocked, the listed number will not be able to connect to your phone until it's removed from the block list.
