There is growing need for mobile forensics due to several reasons and some of the prominent reasons are: Evidential and technical challenges exist.for example, cell site analysis following from the use of a mobile phone usage coverage, is not an exact science.Traditionally mobile phone forensics has been associated with recovering SMS and MMS messaging, as well as call logs, contact lists and phone IMEI/ESN information.

Enterprising mobile forensic examiners sometimes used cell phone or PDA synchronization software to "back up" device data to a forensic computer for imaging, or sometimes, simply performed computer forensics on the hard drive of a suspect computer where data had been synchronized.Consequently, whilst it is possible to determine roughly the cell site zone from which a call was made or received, it is not yet possible to say with any degree of certainty, that a mobile phone call emanated from a specific location e.g. As a result of these challenges, a wide variety of tools exist to extract evidence from mobile devices; no one tool or method can acquire all the evidence from all devices.It is therefore recommended that forensic examiners, especially those wishing to qualify as expert witnesses in court, undergo extensive training in order to understand how each tool and method acquires evidence; how it maintains standards for forensic soundness; and how it meets legal requirements such as the Daubert standard or Frye standard.As a field of study forensic examination of mobile devices dates from the late 1990s and early 2000s.The role of mobile phones in crime had long been recognized by law enforcement.
