What is a Handler for a Cell Phone

One frequently-asked question regarding cellular phones and service is, "What is a handler for a cell phone?" The question most often arises when a consumer attempts to view content, download a ringtone, or use a service and is presented with the message "This application requires a handler."

So what is a handler for a cell phone? In simple terms, it is a plug-in or add-on program for the cell phone that will allow the user to view video content, add ringtones, or access services that the original software provided with the phone does not support. In many cases, a handler cannot be uploaded to the phone due to limitations of memory or software configuration. However, sometimes a handler can be obtained directly from the cell phone manufacturer or through third-party vendors.

Third-party software should be installed with caution, since it may not always be compatible with the cell phone’s original operating system. Some cell phone providers have safeguards against handlers being installed that are not part of the original phone software package; in these cases, installing a third-party handler can void the warranty on your phone or render it inoperable.

Finding a handler for various content types can be challenging. By far the simplest way to determine what handler will serve your particular needs is to contact your cell phone service provider or the manufacturer of your phone directly. In some cases, you may discover that your phone is simply not equipped for the function you are trying to access; an upgrade to a more advanced phone may resolve the problem. If a manufacturer’s handler is available for your phone, typically you will have to install an upgraded software package; this will usually affect a number of different functions and represents an overall upgrade of all software in residence on the phone.

While third-party vendors may be able to provide some handlers, they are essentially plug-ins and may not allow full functionality or may conflict with other programs currently resident on your phone. Generally, the best resolution is to obtain handlers approved by your phone manufacturer and your cellular service provider; this will ensure the proper function of your phone service and protect your warranty coverage in the event that problems arise after installation.
