SECURE MESSAGES The content of the message is encrypted before sending. Only after the message has been delivered to the receiver, the content is decrypted. Except from the receiver, nobody can decrypt and read the message. SECURE FILE TRANSFER Sending encrypted documents, images or any other files. The Silentel application offers to take a picture or video using the camera, record a audio and send it as a file to any recipient in an easy and simple way.
