Deleting phone numbers only removes some of the data your phone may have. Many phones can store data like phone logs, emails, application data, images voice recording and more so if you think you’ve gotten rid of all the data your old phone has you may be wrong. If your information is stored on a phone with a sim card, all you need to do is remove the sim card and you’re done. Always try to overwrite or reformate data on your phone before you get rid of it. Even if you erase the data it can still be recovered and phones are worse than PCs because of the different type of memory they have.

You should be able to find information in the manual that came with the cell phone on how to delete date or reformat it. Sometimes you may find the information you need by searching the manufacturer’s website. The same can’t be said for your service provider. They usually won’t be able to help but you can request that your contact information be deleted from their system if you plan to not use their service any longer.

You can also try a mobile data eraser which this may delete or reformat you’re phone depending on whether the manufacture has included the reformatting option. Deleting data remotely is possible from some services. It is mainly used for protecting stolen phones. Some are set up to delete data if the passwords is wrong too many times or if a message is sent to the phone.

Sometimes you may not be able to delete or reformate the data on your phone. So you may want to try to trick it by uploading fake data and it might overwrite your existing data this will only allow useless data to be taken from that phone and always remove your SIM card if you have one. Phones, as they become more and more like computers, will have to deal with higher risks of security.

 Now you can email, surf the web, download video, download applications. All of these things are actually making your phone into a portable computer. This is convenient but it also adds to the possibility of security risks because you have so much access to the internet in so many different ways.
