All mobile phones contain data (contacts, phone numbers, messages, etc.), mainly on external memory cards, but some data is also stored or leaves remnants in the internal memory of the phones. Such a constantly used communication device contains a lot of information and details about our personal and/or professional life.
The method of data destruction for mobile phones, like USB Sticks, Memory Cards, and SIM Cards, is through “physical destruction” since data storage is electronic rather than magnetic, making degaussing ineffective. Therefore, the data destruction of mobile phones is achieved through the physical destruction (shredding, etc.) of their internal circuit boards.
