Mobile phones play an important role in our daily lives. The capacity and usage of phones with the development of modern technology have turned them into substitutes for personal computers. They can therefore be used in ways similar to those of actual computers, which means a phone SIM card could include not only phone contacts, but also text messages and various files. In many cases, these files could be lost from the mobile, be accidentally deleted or the SIM card itself might no longer work. Extracting data from a phone SIM card or internal memory is a complicated process, which needs specialised technicians.
