    • Complex encryption and talk algorithms
    • Protects against interception complexes
  • Minuses

    • Not protected when calling ordinary phones - only conversations from a cryptophone to a cryptophone are encrypted
    • For calls in a secure mode, you need a stable Internet connection (Wi-Fi, in extreme cases, 3G)
    • Considering the fact that a regular SIM is inserted into the cryptophone, exposed to any impact, it becomes possible to determine the location, social circle and make attacks at the SIM level
    • Finding such a device in the GSM network attracts more attention
    • A cryptophone is a proprietary device and what official manufacturers actually lay in its software, we can only guess
    • Lack of roaming free movement

  • Degree of protection

  • Pros

    • Possible to use on your phone, does not require additional devices

    • Phonetic features - those data by which you can easily find the subscriber of interest
    • One call or message to the number from the subscriber’s address book (for example, to a relative or business partner’s number) immediately makes the subscriber visible
