BlackBerry Messenger gives BlackBerry users a quick, easy way to send instant messages to each other using their PIN codes. Its free and, unlike with e-mail, users can carry on several conversations at the same time. They also can chat with a group, see contacts availability, send files and track message status.

Is BlackBerry messenger secure?

BBMe can be downloaded on any device that uses Android, iOS, Windows or MAC operating systems. The sender and recipient each have unique public/private encryption and signing keys. These keys are generated on the device by a FIPS 140-2 certified cryptographic library and are not controlled by BlackBerry.
