Mobile Phone Directory
Mobile phone directory concepts are difficult to develop further than the idea that a mobile phone directory is a good idea. As many people have privacy issues about their mobile phone number, a mobile phone directory needs to have people sign up with it. Further problems stem from people wanting restrictions on who can have their number. Asking questions to those signing up to a mobile phone directory is no barrier to those who would abuse it, as there is no reasonable way of determining whether the user of the mobile phone directory is telling the truth or not. Concerns of telemarketing companies and stalkers are very serious issues that stop the compiling of a comprehensive mobile phone directory.
There are a few things that function much like a mobile phone number directory, though. There are certainly barriers to how useful these can be, but with no better options available, they can occasionally be useful.
Social Networking Sites As A Mobile Phone Directory
As some social networking sites allow users to list their contact details, they can effectively be used as a mobile phone directory. Many social networking sites have features that allow people to restrict who may view their details and the user must voluntarily give up their information, so this means they work well in providing a relatively secure mobile phone directory. However, most of the features that secure details require that you contact the person in another form first or even be approved. If you search for someone who has put restrictions on their details, contacting them via other means first somewhat nullifies the point of the mobile phone directory function. Essentially, this means that social networking sites can function as a sound mobile phone directory if you forget the numbers of your friends, but they are little use as a mobile phone directory for contacting new people.
There is something of a generation gap in the use of a social networking site as a mobile phone directory, too. Social networking sites are quite popular with younger people, but more mature individuals are less likely to sign up. This means social networking sites can easily serve as a mobile phone directory for younger people, but they are poor for such a purpose for the older crowd.
Online Mobile Phone Directory
There are a few sites that offer very basic online mobile phone directory services. These are voluntary mobile phone directory services, where users must sign in so that they may view mobile phone numbers and join with their own details. While this is a good idea, it is not particularly practical, as many of the sites list numbers internationally. That may be useful on occasion, but generally there is unlikely to be enough information provided to ascertain whether a listing is the person you intended. An online mobile phone directory requires quite a bit of extra detail, which not everyone will be willing to provide. Nevertheless, if you have a lot of time to search for a number and you don't mind making a few wrong calls, then there are certainly uses for an online mobile phone directory.
