There are many people who oppose the system of a cell phone directory. This comes in handy to lookup cell phone number which is a major advantage. However the opponents of cell phone directory do not wish that the public have access to their cell phone numbers. They would prefer that all information pertaining to their cell phone remain private. They also do not want the telemarketers to access their numbers from the free cell phone directory and give them nuisance calls. A majority of cell phone subscribers dread this because they know that the telemarketers can make annoying calls that can be very disturbing. Other personal and confidential information can also be made public which they do not prefer. If cell phone numbers become public those who are against the concept of cell phone directory believe that their personal information will no longer be private which can be cause for worry.
