Cell phones are becoming increasingly capable of storing more and more data. Some models are currently able to store up to 128 gigabytes of information without the need for an additional storage module. This is enough to store around 57,000 average photos, not to mention how many documents, contacts, and other personal information. In addition to the onboard storage, cell phones and tablets now have SD (secure digital) cards as well as SIM (subscriber identity module) cards. Both of these cards hold sensitive personal information.
