Have you ever wondered about the technical aspects of your cell phone?

You can find out about these technical details and other valuable details by using the cell phone test mode found in a wide range of cell phones. For many phones, the cell phone test mode software application is pre-installed in the phone.

To access the cell phone test mode in your phone, many brands require that you enter a code into the phone. Once entered, you will be provided with options such as checking your phone's network statistics and various technical details. You will also have the ability to run a series of hardware tests on your cell phone. A popular function that many people use this software application for is to check the phone's actual signal strength in numeric form. The numbers detailing the cell phone's signal strength generally range from -50 to -105. The number closet to zero indicates a better signal quality. Your cell phone may use positive numbers instead of negative ones, however, the number closest to zero is still a sign of the stronger signal. For example, a signal strength of -65 is a better signal strength than one of -95. Other test mode details provided by some phones include: The TMSI number, paging or time slot information, PLMN codes, neighboring cell tower details, cell ID, location area code, system ID number and TDMA timing advance.

Having the ability to check the functionality of your cell phone in this manner is a valuable tool that many people do not even know their cell phone possesses. Knowing more about your cell phone's technical aspects and abilities will help you get the maximum effectiveness out of your phone's usage, and help you to troubleshoot if ever required.
