CellTrust SecureSMS™Micro Client




SecureSMS Micro Client is a light application that installs on the handset to communicate with CellTrust SecureSMS Gateway. The application is similar to a regular SMS editor and encrypts outgoing secure messages as well as decrypts incoming secure messages received via SecureSMS Gateway.

SecureSMS Micro Client is password protected and erases secure messages upon unauthorized access attempts. When issued by CellTrust SecureSMS Gateway, the remote wipe feature removes all secure messages on the handset in the event the phone is lost or stolen. SecureSMS phonebook keeps track of confidential numbers and identifies the sender by the names of your choosing.

All of your outgoing messages receive confirmation of delivery and read with the exact date and time stamp. For incoming messages, Micro Client automatically issues a tamper-proof acknowledgment to the sender via SecureSMS Gateway when the message is received or read by the recipient. An intelligent self-updating feature ensures the mobile phone is always operating with the latest version of SecureSMS and is benefiting from its most recent features.

The CellTrust SecureSMS FAVE Icon on the mobile phone can be rebranded to reflect your organization's identity. Furthermore, messages for each organization maybe identified by their short code number, keyword or any name specified in the SecureSMS phone book.

Micro Client Registration

In order to complete the installation process, the user needs to register by identifying their resident country and they will then be asked to create a SecureSMS password. If the version that is being installed is certified, installation will be completed with a minimum number of questions and prompts. Otherwise, the user maybe prompted with additional confirmation (e.g. allowing communication with a server).

Note: Although SecureSMS has been certified by many mobile platform/operating system/handset manufacturers and carriers, it still functions properly on most compatible devices for which certification has yet to be achieved.
