AT&T Secure Messaging enables the exchange of encrypted messages between businesses, enterprises and government agencies who are using AT&T Global Smart Messaging Suite powered by Soprano.
AT&T Secure Messaging ensures your sensitive personal data is protected - for example, a one-time password from your bank/online payment broker or a healthcare appointment reminder. Your secure messages are encrypted, then sent to the AT&T Secure Messaging mobile application and decoded, ready for you to read.
