Am from San Jose, California and currently subscribed to T- mobile. I recently got into a fight with my one of my friend and for that reason the person has been adamant on calling me again and again and its really been a very bad experience since it has created much disturbances in my personal life. I want to simply block my friends number on my phone’s to stop him from creating disturbance in my daily life. I want to know how to block a phone number on your cell. Every suggestion is welcome.
